Neutrik’s Timbre plug, made for toggling between capacitors.
Let’s begin with some typical additional capacitance values that certain lengths of cable (or capacitors) can bring to your system:
• 10’ vintage coiled cable (approx. 3 meters) -> 1 nF
• 15’ vintage coiled cable (approx. 4.5 meters) -> 1.5 nF
• 20’ vintage coiled cable (approx. 6 meters) -> 2.2 nF
• 30’ vintage coiled cable (approx. 9 meters) -> 3.3 nF
• Ritchie Blackmore-style, ultra-long vintage coiled cable -> 4.7 nF
I listed standard values here, so you should have no problem getting caps to match them in any local electronics store or online; the type of cap doesn’t really matter and will mostly be dominated by size, but I’ll share more about this in a minute.
Let’s quickly summarize the first installment of this column from last month’s issue: From a technical point of view, added capacitance shifts down the resonance frequency of the pickups, so they sound fatter, especially when using overdrive. This is exactly the reason why a lot of distortion and fuzz boxes with a vintage voicing use an additional cap at the input section; the resulting overdriven tone is fat and warm.
This month’s mod, which involves adding a capacitor to your signal, works best with vintage-flavored single-coil pickups (approximately 2.4 H inductance) or a typical old-school PAF-style pickup (approximately 3.8 H inductance). Modern high-output pickups are often sporting inductances of 6 H to 8 H, and don’t sound very good with this mod—when adding more cable capacitance to such pickups, the result is a dull and wooly tone without any clearness and definition. If you want to make your single-coil guitar sound more Les Paul-ish, you should try a 4.7n capacitor. It will shift the resonance frequency of your single-coil pickups down to the typical PAF ballpark, making for a very cool and usable old-fashioned guitar tone. It might feel a little muffled when playing clean, but ultra fat and punchy when using overdrive! In general, values higher than 4.7n are not recommended.
We have two options for where to install our cap.
On the Guitar Cable
This is the easiest location to add additional capacitance to your system, with several mod options:
1. The lightest mod ever isn’t a mod at all—it’s to simply buy a vintage guitar cable and plug it in whenever you need it! I don’t know of any company that offers modern guitar cables with intentionally high capacitance.
2. The Neutrik company offers a special angled plug, called the Timbre Plug, that you can solder to any guitar cable of your choice. The plug has a 4-way rotary knob on top to toggle between different capacitors. In addition to a bypass setting, the plug offers capacitances of 1nF, 2.2nF, and 3.3nF, letting you simulate different cable lengths on the fly.
3. You can add an additional capacitor to any guitar cable of your choice to convert it into a “longer-sounding” cable. You simply open one of the plugs to solder the cap between the hot and ground—that’s it. Small, 2.5 mm contact spacing ceramic caps are easy to put into a standard plug and are your weapon of choice here. It’s essential to only add the additional cap to one of the two plugs, but it doesn’t matter if you plug this side into your guitar, an effect, or your amp. This method allows you to build yourself some cables that simulate their older, longer relatives.

Inside the Guitar
You can also add a cap (or several) inside your guitar if you only need this mod for one instrument. If you’re looking for added capacitance with all your guitars, you’d be better off choosing one of the techniques mentioned above.
1. The easiest way is to solder your additional capacitor directly to your volume pot; this way it has a fixed value that can’t be changed and is always engaged. This operation is very simple to do, and you can use regular-sized caps for this.

2. If you want to make the cap switchable, such that you can run it either bypassed or engaged, you can install a SPST mini toggle switch or use half of a push-pull or push-push pot, which usually sport a DPDT switch underneath.
This drawing shows how to make your additional cap switchable.

3. If you want to use more than one cap to simulate different cable lengths, your weapon of choice is a rotary switch, setting up a kind of Gibson Varitone wiring without the inductor. Because we are switching capacitances, it is essential to run an additional 10 meg resistor in parallel to each of the caps, and to use a make-before-break, not a break-before-make, rotary switch to prevent loud popping noises when using the switch while your guitar is plugged into an amp. Leave the first lug of the rotary switch open for the bypass position without an additional cap.
If you want to use more than one cap to simulate different cable lengths, use a rotary switch.

4. If you want to make this mod even more flexible, you can add an additional “cable simulator pot” to your system. The pot should have the same resistance as your volume pot, and should be wired to your volume pot. This way, for example, you can add a 3.3nF or 4.7nF cap to the extra pot, and dial in as much cable capacitance as you like.
On the Pedalboard
The idea of putting a rotary switch or cable-simulator-pot solution into an external unit to create a kind of extra-capacitance stompbox to use with all of your instruments is just around the corner, and yes, it’s possible! However, I don’t recommend this, because it’s physically located after the volume pot in the guitar, which means less volume (no unity gain) and less high end. But don’t worry: If you are looking for a pedalboard solution to simulate different cable lengths (which, as we defined earlier, means to shift the resonance frequency of the pickups), there are some active solutions on the market offering such a feature, usually in combination with a boost or buffer functionality. To name just a few, you should look into the Seymour Duncan Pickup Booster, Stellartone Micro Pedal, or the i2e Audio AG1.0 The PURR. Along with some other brands, these pedals will do the trick, and they’re not difficult to build if you are looking for a DIY solution.
So far, I’ve received several emails from readers asking for some more DIY guitar tools, so next month, we will look into some sustainable and environmentally friendly DIY guitar helpers—all of which you can build yourself easily by upcycling things you already have at home. Stay tuned!
Until then... keep on modding!
Today, the choice of guitar cables is better than it’s ever been, and you can choose between countless options regarding color, stability, plug style, length, diameter, bending strength, shielding, etc. A lot of companies offer high-quality cables in any imaginable configuration, and there are also cables promising special advantages for specific instruments or music styles, from rock to blues to jazz.
Appearance, stability, longevity, bending stiffness, and plug configuration are matters of personal preference, and every guitarist has their own philosophy here, which I think is a great thing. While one player likes standard black soft cables with two straight plugs, their buddy prefers red cables that are stiff as hell with two angled plugs, and another friend swears by see-through coiled cables with golden plugs.
“We often want to come as close as possible to sounding like our personal heroes, but we fail because we’re using the wrong cable for a passive guitar.”
Regarding reliability, all these parameters are important. Who wants a guitar cable making problems every time you are on stage or in the studio? There are also technical parameters like resistance, capacitance, transfer resistance on the plugs, and more. Without making it too technical, we can summarize that, sound-wise, the only important technical parameter for a passive guitar circuit is the capacitance of the cable. Sadly, this information is often missing in the manufacturer’s description of a guitar cable, and there’s another thing we have to keep in mind: Most manufacturers try to offer cables with the smallest possible capacitance so the guitar can be heard “unaltered” and with a “pure” tone. While these are honourable intentions, they are self-defeating when it comes to making a guitar sound right.
Let’s take a trip back to the past and see what cables players used. Until the early 1980s, no one really cared about guitar cables—players simply used whatever was available. In the ’60s and ’70s, you could see a lot of ultra-long coiled cables on stage with players like Clapton, Hendrix, May, Townshend, Santana, and Knopfler, to name just a few. They used whatever was available, plugged in, and played without thinking about it. Ritchie Blackmore, for example, was famous for notoriously using incredibly long cables on stage so he could walk around. Joe Walsh and many other famous players did the same. Many of us have these players’ trademark sounds in our heads, and we often want to come as close as possible to sounding like our personal heroes, but we fail because we’re using the wrong cable for a passive guitar. So what are we talking about, technically?
It’s important not to look at the guitar cable, with its electrical parameters, as a stand-alone device. The guitar cable has to be seen as part of the passive signal chain together with the pickups, the resistance of the guitar’s pots (usually 250k or 500k), the capacitance of the wires inside the guitar, and, of course, the input impedance of the amp, which is usually 1M. The interaction of all these in a passive system results in the resonance frequency of your pickups. If you change one of the parameters, you are also changing the resonance frequency.
”Ritchie Blackmore, for example, was famous for notoriously using incredibly long cables on stage so he could walk around.“
You all know the basic formulation: The longer the cable, the warmer the tone, with “warmer” meaning less high-end frequencies. While this is true, in a few moments you will see that this is only half the truth. Modern guitar cables are sporting a capacitance of around 100 pF each meter, which is very low and allows for long cable runs without killing all the top end. Some ultra-low-capacitance cables even measure down to only 60 pF each meter or less.
Now let’s have a look at guitar cables of the past. Here, capacitances of up to 400 pF or more each meter were the standard, especially on the famous coiled cables. See the difference? No wonder it’s hard to nail an old-school sound from the past, or that sometimes guitars sound too trebly (especially Telecasters), with our modern guitar cables. This logic only applies to our standard passive guitar circuits, like those in our Strats, Teles, Les Pauls, SGs, and most other iconic guitar models. Active guitars are a completely different ballpark. With a guitar cable, you can fine-tune your tone, and tame a shrill-sounding guitar.
“No problem,” some will say. “I simply use my passive tone control to compensate, and that’s it. Come on, capacitance is capacitance!” While this logic seems solid, in reality this reaction produces a different tone. “Why is this?” you will ask. Thankfully, it’s simple to explain. You might be familiar with the typical diagrams showing a coordinate system with "Gain/dB" on the Y-axis and "Frequency/kHz" on the X-axis. Additional cable capacitance will shift the resonance frequency on the X-axis, with possible differences of more than one octave depending on the cable. A cable with a higher capacitance will shift the resonance frequency towards the left and vice versa.
Diagram courtesy Professor Manfred Zollner (https://www.gitarrenphysik.de)
Now let’s see what happens if you use your standard passive tone control. If you close the tone control, the resonance frequency will be shifted downwards mostly on the Y-axis, losing the resonance peak, which means the high frequencies are gone. This is a completely different effect compared to the additional cable capacitance.
Diagram courtesy Professor Manfred Zollner (https://www.gitarrenphysik.de)
To summarize, we can say that with different cable capacitances, you can mimic a lot of different pickups by simply shifting the resonance frequency on the X-axis. This is something our passive tone control can’t do, and that’s exactly the difference you will have to keep in mind.
So, let’s see what can be done and where you can add additional cable capacitance to your system to simulate longer guitar cables.
1. On the cable itself
2. Inside the guitar
3. Externally
In next month’s follow-up to this column, we will talk about different capacitances and how you can add them to your signal chain with some easy-to-moderate modding, so stay tuned!
Until then ... keep on modding!
Note the cavity cover on the back, which houses the components of Andy Summers’ mid-boost system.
In general, you can use any Telecaster and convert it to Andy Summers’ specs. If you want to stay as close as possible to the original guitar, the way to go is an alder body—just like Andy’s, which is 2-piece—with a 3-tone sunburst finish and white double binding.
The neck should be quarter-sawn, 1-piece maple with a C profile, 21 vintage-style frets, and a 7.25" fretboard radius. Of course, you can choose your own specs here, too. The original guitar has a brass nut rather than bone or plastic, and it should be no problem to find a brass nut blank for a Telecaster. You will need different tools to work on it compared to bone, plastic, or graphite, so keep this in mind. If you do not have the right tools or don’t feel comfortable making nuts, you should leave this task to your local guitar tech. Summers’ guitar has Schaller M6 tuning machines, which are still available from the German Schaller company, and two chrome butterfly string trees. You may not really need two of them—usually one for the B and the high E string will do the trick, especially with a well-made nut.
The original has a heavy brass bridge plate with six individual brass saddles, which will increase overall weight significantly. You can still buy this type of brass bridge from several companies, but there are much lighter bridges on the market.
The stereo output jack is installed in a rectangular chrome plate, like on a Les Paul, which I think is superior to the typical Telecaster jack cup. Interestingly, the plate on Summers’ guitar is only held by two of four screws, but do yourself a favor and use all four to make this spot as strong as possible. You should attach the plate really tight, especially when you use an output jack with a tight grip for the plug.
“Electronically, there is nothing too specialized that you will need for the controls.”
The rest of the hardware is chrome and standard: two regular strap buttons, a standard Telecaster control plate, ’60s Telecaster flat-top knobs, a black ’60s-style top-hat switch knob on the 3-way pickup selector switch, and two flat-lever mini-toggle switches. You should have no problem getting all of these parts from any guitar shop. The pickguard is a 3-ply mint green pickguard with a standard humbucker routing for the neck pickup.
Electronically, there is nothing too specialized that you will need for the controls: a standard 3-way pickup selector switch, two 250k audio pots for master volume and master tone, a gain control pot for the booster, and two additional mini DPDT on-on toggle switches for switching the booster on and off and for the phase control of the bridge pickup. The resistance of the gain control pot depends on the booster you want to use: e.g. for the Fender Clapton mid-boost kit, a 500k type will work great.
For the bridge pickup, there is a standard early-’60s-style Telecaster single-coil pickup, and every pickup company will have something like this in their catalog. Because the bridge pickup is installed to an out-of-phase mini-toggle switch, your pickup will need three conductors, with the metal base plate separated from the pickup’s common ground, and a third wire that connects the bridge plate individually to ground. If you have a regular two-conductor model, you need to break this connection, soldering a third wire directly to the base plate.
Interestingly, the bridge pickup on Summers’ Tele is installed directly into the wood of the pickup’s cavity. I see no reason why you shouldn’t install it the regular way on your guitar.
Here’s a close-up of the bridge on Summers’ historic Tele.
Photo courtesy of Ten-Guitars (https://ten-guitars.de)
In the neck position, there is a ’59 PAF humbucker with a conventional two-conductor wiring installed directly into the pickguard in the standard way, with the open pole pieces facing towards the neck. The choice of late-’50s PAF copies has never been better than it is today. You can buy excellent versions from a lot of companies, just make sure to choose the correct string spacing, which is usually called “F-spacing” or something similar, and is usually 2.070" (52.6 mm). (Gibson spacing, or G-spacing, is 1.930" or 49 mm.)
You’ll need humbucker routing on your body to make it fit. If you don’t have a body with humbucker routing and don’t want to get your Tele body re-routed, you can consider one of the numerous stacked humbuckers that will fit into a standard Telecaster neck pickup cavity. My experience is that there is a noticeable difference in tone compared to a full-sized humbucker, and it will be a compromise.
Next is the active booster. Finding a good booster module and wiring it up is much easier than fitting it into the tight space of a Telecaster body. There are a wide range of available booster options. There are complete DIY sets available that include the PCB and all of the necessary parts to build your own, and there are also drop-in PCBs that are already populated, like the well-known Fender mid-boost circuit kit. You can also find mini-sized booster modules using high-quality SMD parts, which only require a fraction of space compared to the regular PCBs.
“Finding a good booster module and wiring it up is much easier than fitting it into the tight space of a Telecaster body.”
The available options include treble boosters, mid-boost circuits, full-range boosters, etc. Choose what you like best. The problem will be that you need to stuff it into a Telecaster body. As you know, there is not much space inside a Telecaster, and you need to add the booster itself, the 9V battery, an additional pot for controlling the booster, and two additional mini-toggle switches—one for turning the booster on and off, and the other to get the bridge pickup out of phase. This is a lot of stuff! On Summers’ guitar, this problem was solved by adding a large cavity on the back and closing it with a plastic back plate, as on a Gibson Les Paul.
A look inside the cavity for the mid-boost unit.

You can clearly see the two big routings for the booster’s PCB and the 9V battery, plus the additional pot to control the amount of boost as well as the mini-toggle switch to turn the booster on and off. If you are not afraid of routing two big chambers into your Telecaster’s body, this is a suitable way to go.
On a Telecaster, there are not many alternatives I can think of to fit all these parts. One possible way of saving space would be to use a stacked pot with two 250k pots for volume and tone, so you have the second hole in the control plate available for the gain control pot of the booster. Between the two pots, it should be no problem to place the two mini-toggle switches. Or you use a push-pull pot for the gain control to save one of the mini-toggle switches. The guitar will look much cleaner, at least from the front side. But you still have to put the booster PCB and the battery somewhere. A customer of mine did this by completely routing the area under the pickguard. But even with only a regular single-coil neck pickup, it was a really tight fit, so with a regular-sized humbucker, it will be close to impossible. So, you or your luthier will have to be creative, and I wouldn’t be surprised if a company offers Andy Summers Telecaster bodies with all chambers already routed.
Here we go for the wiring. Wherever possible, I tried to keep the diagram as clean as possible. The wiring of the booster is only an example and depends on the booster you want to use, but the basic wiring is always the same.
Here’s a helpful schmatic of the Andy Summers‘ Telecaster wiring.

That’s it. Next month, we will take a deep look into guitar cables and wires, what really makes a difference, and how you can use this to reshape your guitar tone. So stay tuned!

Andy’s axe!
Best known as the guitarist from the Police, Summers was born and raised in England. He picked up the guitar at a young age, and moved to London when he was 19, aspiring to become a professional musician. Eventually, he played with some legendary bandleaders, including Eric Burdon and Jimi Hendrix. Summers studied classical guitar and composition in Los Angeles at California State University, Northridge, graduating in 1972. After moving back to London, he played with Joan Armatrading, Jon Lord, Mike Oldfield, and many more before meeting Gordon Sumner (aka Sting) and Stewart Copeland and joining the Police in 1977. The rest, as they say, is history.
The guitar Summers is most associated with—and which you can hear on a lot of the band’s hit records—is a well-worn and heavily modified sunburst Fender Telecaster. Let’s dive into what makes it so unique.
The story goes that before returning to the U.K. from Los Angeles, Summers bought this Telecaster from one of his guitar students for $200 (approximately $1,420 today). It was already highly modified, and Summers instantly fell in love with it. Modifications included a brass nut and brass bridge plate with six individual brass saddles. The bridge pickup was installed directly into the body and there is a humbucker in the neck position, plus it had a phase switch on the bridge pickup and an additional third pot and switch controlling its active boost circuitry. The only mod Summers did on the guitar after receiving it was installing replacement Schaller tuners.
Summers has stated that the guitar is from 1961, although, because of the double binding on the body, it’s quite possibly a sunburst Telecaster Custom from 1963. The serial number on the neck heel indicates 1961, suggesting Fender may have used pre-produced necks from an earlier batch for the first run of Telecaster Customs in 1963. Or maybe it was a custom order from someone who wanted double binding in 1961? Dennis Galuszka from the Fender Custom Shop was the lucky guy who had the pleasure of taking the original instrument apart to closely study it while collecting info for the Tribute series. In September 2024, he told Guitar World: “If I had to guess, it looks like the neck came off a ’50s Tele because it actually had a little white blonde paint—like they used on ’50s Teles—left on the butt. But the neck pocket had no date written or stamped on it, which was weird. And the body has been routed out so much under the pickguard that all traces of a date are long gone.” There are no records at the Fender factory that can shed any more light on this, so it will remain a mystery—but not the only one.
Putting a neck humbucker on a Telecaster was nothing too special at this time; same goes for the phase switch. But while brass hardware had become a popular mod to many guitars by the mid-to-late ’70s, it wasn’t something that was common on Telecasters (or on Fenders in general), making the brass nut and bridge plate unusual.
Another mystery is the active booster circuitry inside this guitar. When the Fender Custom Shop released the Masterbuilt Andy Summers Tribute Telecaster in the mid 2000s, it was equipped with the mid-boost circuit from the Eric Clapton Strat. This circuit first debuted in 1983 in the Fender Elite Stratocaster, 10 years after Summers received this Telecaster. So the circuit used in Summers’ Telecaster must have been a different one. Keeping the timeline in mind, it’s likely that it was one of the many treble-boost circuits from this era—maybe something like the Dallas Rangemaster, EHX LPB-1, or something similar with a single-pot boost control. Or maybe it came from a cannibalized stompbox or was a home-brewed device ... again, this will remain a mystery. My personal guess is that the original circuit in the guitar stopped working after 1983, and one of the guitar techs had to replace it. Maybe Summers was not interested in those details, and as long as there was a boost available, he didn’t care what was going on under the hood.
Belt-buckle rash? A bit.

Another mystery is the identity of the student who he purchased the guitar from. Summers has never shared their name, and we don’t know who modded it. Interestingly, in all those years, no one ever spoke up to earn the credits for this modding work. This alone fuels speculation as to who really did all these mods.
Now, let’s take a look what features this guitar has:
• 2-piece alder body, white double binding, 3-tone sunburst finish
• Quarter-sawn maple neck, C profile, 21 vintage frets, 7 1/4" fretboard radius, brass nut
• Scale length 25 1/2", width at nut 1.650"
• Brass bridge plate with six individual brass saddles
• Schaller M6 tuning machines
• Two butterfly string trees
• Rectangular jack plate held by only two of four screws
• 3-ply mint green pickguard with ’59 PAF humbucker in the neck position and ’60s Telecaster single-coil pickup directly mounted into the body
• Standard Telecaster 3-way pickup selector switch with modern wiring: bridge/bridge + neck in parallel/neck
• 250k master audio volume, 250k master audio tone controls
• Mini-toggle phase switch for the bridge pickup on the control plate
• Extensive routing on the back housing the active boost circuitry, 9V battery, and the additional third pot for controlling the amount of boost, all covered with a homemade backplate out of 3-ply black pickguard material
In the next installment of this column, we will break it down piece by piece, talk about the wiring, and how you can build your own Andy Summers tribute Telecaster, so stay tuned.

Pickup screws with latex tubing.
Here is a step-by-step guide on how to eliminate most of these issues. And if you haven’t faced such problems on your Tele, you can still give these a try, and chances are good that you never will. These procedures will not alter the tone of your Telecaster in any way, so it’s better to have it and not need rather than to need it and not have it.
Checking the Pickups
Over the years, I have seen the wildest things coming stock from the factory, especially on budget pickups: unbent metal tabs on neck pickups, loose metal base plates on bridge pickups, bridge pickups only held by the springs, and other crazy stuff.
Let’s start with the neck pickup. Make sure the cover is installed tightly and is not loose in any way. The metal cover is only held by three metal tabs that are bent around the bottom of the pickup, one of them usually connected to the pickup’s ground. Make sure they are tight, holding the metal cover firmly in place. If not, they need to be re-bent. Be careful to not break them.
“Often, these small metal springs can cause feedback, and I’m sure Leo Fender had his reasons for choosing latex tubing instead.”
On the bridge pickup, the metal base plate on the bottom needs to be attached firmly. Check with your fingers to see if it can move. If so, even in only one spot, you need to re-glue it to isolate vibration. Otherwise, it will squeal at high volumes. This is easy to do, and the easiest and best way is to completely take the base plate off, clean it, and re-glue it with a thin layer of silicone from your local Home Depot.
While you are in there, it’s always a good idea to convert both pickups to 3-conductor wiring by breaking the ground connection of the metal cover (neck pickup) and the base plate (bridge pickup). Attach a third wire to one of the lugs of the metal cover and another one to the metal base plate, and solder both to a grounding point of your choice, e.g. the casing of one of the pots. This can be helpful for future mods, like any 4-way switch mod, where this is a mandatory requirem
Un-springing the Pickup Attachment
If your pickups are attached with metal springs to enable height-adjustment, you should replace them with some latex tubing. Often, these small metal springs can cause feedback, and I’m sure Leo Fender had his reasons for choosing latex tubing instead of metal springs. This is cheap, fast, and easy to do; you can get latex tubing from any guitar store or online for only a few cents. (See photo at top.)
Cushioning the Pickups
On a Tele, there’s usually a gap between the bottom of the pickups and the inside of the guitar’s body. This open space can exacerbate feedback issues. Luckily, it’s easy to solve with a piece of foam.
Using a piece of white paper, outline the routing for each pickup. Cut them out as a template for the foam. Then, trim the foam to shape. Place the foam on the bottom of both pickup routings, and you are done. There is no need to glue or attach the foam in any way.
It’s important that the bottom of the pickup is touching the foam so there is no more open gap. I usually use foam that is a little bit thicker than necessary, so the pickup will press on it slightly, making a perfect connection. The type of foam is not important as long as the gap is closed. I prefer to use foam rubber that is easily available in a variety of thicknesses.
Closing Support Routings
On a lot of Telecasters, you can find open support routings from the neck pickup routing towards the electronic compartment. This is for easier access when running the wires of the neck pickup through the body.
Note the various cavities in this typical Telecaster body.

There are two ways of routing the wires of the neck pickup through the body: from the neck pickup routing directly into the electronic compartment or into the routing of the bridge pickup, and from there into the electronic compartment, which is the traditional way. In the latter case, make sure all the wires are running underneath the additional piece of foam. If you have any open support routings on your Telecaster body, put some foam in to close them. You don’t need to attach the foam; the pickguard will hold it in place. The kind of foam doesn’t matter, and you can also use things like a small piece of cotton cloth, cotton wool, Styrofoam, etc. in there.
Addressing Bridge Plate Flaws
One of the most common reasons for unwanted feedback is the typical Telecaster bridge plate. The Telecaster bridge system was designed in the ’40s by Leo Fender himself and is crude at best. Its function was simply positioning the strings and providing a rough, easy adjustment of the intonation and the string-height settings. It wasn’t long before Fender released the much-improved bridge design found on the Stratocaster.
The current production Fender vintage bridge plate, as well as most budget aftermarket bridge plates, is made from thin hot-rolled steel in a deep-drawn process. Using this manufacturing process, parts can be made very quickly and cheaply, but at severe cost in quality. The steel used must be very soft and thin to allow it to fold and bend in the corners.

Unfortunately, this process creates unusual internal stress in the steel, which can bow the plate so it can’t sit flat on the wooden body. This is a common reason for unwanted feedback on so many Teles. Interestingly, the early vintage bridge plates Fender made used a cold-rolled steel procedure to relieve stress in the material and to avoid this problem. Long live modern mass production!
If you have a Tele with a bowed bridge plate, there are three possible things you can do:
• Change the bowed bridge plate for a straight and even one. (This is the easiest way to avoid any troubles.) There are excellent replacement bridge plates on the market, so you’ll have plenty of choices for materials, designs, finishes, etc.
• Get the bowed bridge plate to a metal fabricator or tool maker so they can try to solve the problem for you. This process will probably cost you more than a new bridge, so this is only an option if it’s a special bridge you want to keep, no matter the cost.
• Drill two small additional holes on the front of the bridge plate, shown as red dots in the picture. After re-installing the bridge plate on the guitar, tightly drill two wood screws through these holes. Often, modern replacement bridges already have these two additional holes. In many cases, this will do the trick, so you don´t have to buy a new bridge.
If you have gone through this entire list and still have problems with feedback, it’s very likely that the pickup itself needs to be re-potted, which a pickup builder can do for you.
Next month, we will stay on the Telecaster subject, taking a close look at the famous Andy Summers Telecaster wiring, so stay tuned!
Until then ... keep on modding!
