Believe it or not, on eight out of 10 guitars with tuning problems, the culprit is usually bad strings or the exotic ways they were installed. Here are some ways to combat these issues.
Welcome back to Mod Garage. I’ve wanted to cover this topic for a long time, but to be honest, I didn’t dare because it seems so trivial. I’m sure a lot of you already have a natural routine to assess tuning, but I receive guitars daily for repairs, and enhancing tuning stability is something I hear about a lot—on electric as well as acoustic guitars. There are many reasons why a guitar has problems staying in tune, but today we’ll discuss the simplest one: the strings.
A column about strings? Now he’s crazy, you might say. Believe it or not, on eight out of 10 guitars with tuning problems, it turns out this is caused by the strings themselves and/or the way the strings were installed. For some guitars, the nut or the saddle/tremolo is causing problems; others have problems with the tuners or worn-out bridge pins on acoustic guitars, string trees, etc. But bad strings and exotic ways to install them are reason No. 1 for tuning problems. Let’s have a deeper look into what happens here and what can be done.
“The more windings you have on your posts, the greater the chance for tuning problems.”
Over the years I’ve seen the craziest things people do with their strings. Here are some simple guidelines for you to combat tuning problems, whether it’s an electric or acoustic guitar, or if it has steel or nylon strings.
Possible Problem No. 1: The Strings Themselves
You all know this “problem” when setting up new strings on a guitar: After getting them in tune and playing for a minute, you need to tune them again, and this will last for some time, depending on the material of the strings. This is normal when strings are getting stretched for the first time; they’ll stay in tune after they’ve settled. Here are some hints to get around this:
1. Stretching the strings several times after setting them up by simply pulling them upwards with your hands will speed up this process noticeably. There are also tools for this called string stretchers, but you can simply do it with your hands. This is called pre-stretching and is very simple to do. As a rule of thumb, steel strings will settle sooner than nylon strings.
2. A customer bought “pre-stretched strings” and brought them in so I could try a set of these in the shop. I could notice no difference other than the price, but I wanted to mention that such sets exist.
3. Cryogenic-treated string sets may stay in tune faster right from the start. This treatment is widely used to remove tension, especially out of metal parts—like on high-precision components for racing engines. This might work on steel strings, but I have my doubts that it will work on nylon strings. Funny enough, I’ve never read about tuning improvement on any cryogenic-treated string set, but a lot is mentioned about how good they sound, how long they will last, etc. It’s up to you if these strings sound any different from other string sets. Give it a try. In time, each string set should stay in tune without any problems, no matter what method you use to speed things up.
“Cryogenic-treated string sets may stay in tune faster right from the start.”
Some time ago, I had a British-made Burns guitar from the ’60s on the workbench that was still equipped with the original flatwound string set it came with from the factory. These strings were perfectly in tune after almost 60 years. If the strings aren’t damaged, there should be no problem. A problem I regularly see is that completely new string sets have a rotten egg under the hood, caused by problems during manufacturing. From my experience, it’s mostly steel strings of certain brands and very often the G string, but I’ve also had bad D and B strings out of the box. With such strings, no matter what you try, you can’t get them in tune, and you’ll see they have an unnatural pattern of movement. I have no idea what causes this problem during manufacturing, but just keep this in mind if you run into tuning issues with a new set of strings. The solution is simple: Replace the bad string or the whole set with a new one.
Possible Problem No. 2: The More, the Merrier
Many people think it’s right and important to wind up the complete string length so it can stay in tune better because of the many windings, adding stability (Photo 1). Exactly the opposite is true. The more windings you have on your post, the greater the chance for tuning problems. Getting as few windings as possible on the post is the way to go. Have a look at a locking tuner. They have zero windings on the post for the best possible tuning stability. We’ll talk about how to do this in a minute. The best and funniest statement I’ve heard over the years was from a customer, when I tried to explain that it’s not a good idea to wind up the complete string length. He explained he’ll continue doing this because the manufacturer has good reasons to choose this length. I suppose somebody must do whatever makes somebody happy.
Possible Problem No. 3: Loose Tuners
Whenever you change your strings, make sure all screws and hex nuts from your tuners are tight. With a loose and moving tuner you’ll not only have tuning problems, but it’s also a common source for strange noises you can even hear in the amplified tone of a guitar. Sounds trivial but it’s important.
Possible Problem No. 4: Improper String Installation
This is by far the most common problem, and everyone has their own way of stringing up guitars. Some are superior to others. I don’t say my method I use in the shop is the best and only way that works. But over the years I tried a lot of different methods and the one I want to show and recommend to you is the best-working one for me. It incorporates what we just talked about: putting the least windings possible on the post for maximum tuning stability, mimicking the way a locking tuner works. This works on all standard tuners and is very easy to learn, so give it a try.
If you don’t want to compromise, there is no way around using locking tuners on your guitar. But if locking tuners are 10/10, the winding method that follows is 8.5/10, which is not bad at all.
I’m showing the winding method on an acoustic guitar with a 3/3 tuner configuration, but it also works with a 6L or 6R tuner configuration. It won’t work with the ’50s vintage Kluson types you often see on Stratocasters and Telecasters because there is no string hole on the post other than the one on top.
1. Position the post of the tuner so the string hole will be in line with the corresponding string slot for a string on the nut.
Photo 2
2. Guide the string through the string hole of the post and leave only a little slack. As a guideline, if you can put the fingers of your right hand underneath the strings, that’s enough. Now, use a finger of your right hand and lock the string after the nut, leaving a little slack lying on the fretboard (Photo 2). I like to snip off a good portion of the rest of the string at this point, to make the following process easier. But you can also leave it full length until you’re finished—whatever you like best.

3. Bend the rest of the string around the post sharply so it will form a “V.” Don’t forget to still keep the string locked with a finger (Photo 3).
Photo 4
4. Next, put the rest of the string underneath the string, pressing it firmly against the post, still locking the string with your finger, and bend it over the string (Photo 4 and Photo 5).
Photo 5
5. Tune up your string and release the finger you used to lock the string. You’ll only need a very small movement of the tuner to get the string up to tune, so this is something you’ll have to get used to. Cut off the rest of the string and you’re done (Photo 6).
Photo 6
On a 6-in-line tuner configuration, you can proceed with the other strings as shown. With a 3/3 configuration, you’ll have to mirror the process with the G, B, and high-E string. The rule of thumb is the rest of the string is always bent towards the middle of the headstock to create the “V.”
It’s very simple to do and very effective. It’s also important to lock the string with your finger during the whole process until it’s up to tune.
When you have a guitar that won’t stay in tune, chances are good that this is all you need to do. If this doesn’t help, at least you did everything that could be done before consulting your local luthier. And your luthier will be impressed about your troubleshooting, for sure. It will save them some time troubleshooting and it’ll save you some bucks, too.
Next month we’ll finally finish our DIY relic’ing project, so stay tuned.
Until then ... keep on modding!

This wonky Zim-Gar was one of many guitars sold by importer Gar-Zim Musical Instruments, operated by Larry Zimmerman and his wife.
The 1960s were strange days indeed for import guitars, like this cleaver-friendly Zim-Gar electric.
Recently I started sharing my work office with a true gem of a guy … one of the nicest fellas I’ve ever come across. If you’ve been following my column here, you might remember my other work mate Dylan, who is always telling me about new, fad-type things (like hot Honey guitars) and trying to convince me to use AI more. (What can I say, he’s a millennial.) But Steve, on the other hand, is about 10 years my senior and is a native New Yorker—Brooklyn actually, from the Canarsie neighborhood. Steve is a retired teacher and spent many years teaching in the Brownsville area of Brooklyn, and man, he has some amazing stories.
Mostly we talk about music and sports (he’s exiled here among us Philadelphia sports fans) and he’s just endlessly interesting to me. He has a huge appetite and can eat a whole pizza. When he talks, he sounds like one of the Ramones and he still has an apartment in Rockaway Beach. We both love Seinfeld and, like George Costanza, Steve knows where all the great bathrooms are across New York City. Since he’s been added to my circle (and is such a mensch), I decided I should work him into a column.
So here’s the connection: Back in the day there were many American importers, dealers, and wholesalers. A lot of them were based in New York, Chicago, and Los Angeles, but I only know of one guitar importer located in Brooklyn: Gar-Zim Musical Instruments. The company was run by Larry Zimmerman and his wife, and the couple had some success importing and selling Japanese guitars and drums. I used to see early Teisco imports with the Zim-Gar badge, which was the brand name of Gar-Zim. I’ve also seen Kawai guitars with the Zim-Gar label, but the Zimmerman’s seemed to sell cheaper and cheaper gear as the ’60s wore on, including the piece you see here.
“This build reminds me of the cutting boards I used to make in wood shop back in my high school days.”
The model name and factory origin of this guitar is a mystery to me, but this build reminds me of the cutting boards I used to make in wood shop back in my high school days. The guitar is just flat across the top and back, with absolutely no contouring or shaping. Its offset body is plywood with a thin veneer on the top and back. From a distance this guitar actually looks kind of nice, but up close you can see a rather crude and clunky instrument that offers little flexibility and playability. The non-adjustable bridge is off center, as is the tremolo. It was really hard to get this guitar playing well, but in the end it was worth it, because the pickups were the saving grace. Another example of gold-foils, these units sound strong and raw. The electronics consist of an on/off switch for each pickup and a volume and tone knob. The tuners are okay, and the headstock design is reminiscent of the Kay “dragon snout” shape of the mid to late ’60s, which is where I would place the birthdate of this one, probably circa 1966. Everything is just so goofy about this build—even the upper strap button is located on the back of the neck. It reminds me of that era when simple wood factories that were making furniture were tasked with building electric guitars, and they simply didn’t know what they were doing. So, you get oddities like this one.
Gar-Zim continued to sell guitars and other musical instruments through the 1970s and possibly into the ’80s. I once even saw a guitar with the label Lim-Gar, which is totally puzzling. I think there should’ve been a Stee-Gar designation for my new buddy Steve-o! Yes, good readers, with guitars and me, there are always just a few degrees of separation.

Our columnist’s silver-panel Fender Bandmaster.
How this longstanding, classic tube amp design evolved from its introduction in 1953.
I have a silver-panel Bandmaster Reverb that I don’t think I’ve talked about enough in this column. It’s one of the most versatile and flexible amps I own, so I use it for everything. It’s portable, has tube-driven reverb and tremolo, and has a full set of EQ knobs including the critical bright switch, which we discussed the importance of earlier this year (“How to ‘Trebleshoot’ a Vintage Fender Amp,” March 2025). The amp is not only pedal-friendly; the flexible 4-ohm output impedance will handle almost all speaker configurations and sound any way you’d like. Let’s take a deeper look at the Fender Bandmaster amp and walk through its development through the years.
The first Bandmaster was introduced in 1953 as a wide-panel tweed amp with Fender’s 5C7 circuit. This rare combo was loaded with a single 15" Jensen P15N and powered by dual 6L6GC tubes in push-pull configuration to produce a modest 25 watts. The 6L6GCs were cathode biased and along with the 5U4GB rectifier tube contributed to a forgiving sag, early breakup, and a midrange-y voice.
Fender made several changes when they launched that amp’s successor in 1955, the more widely known 5E7 narrow-panel Bandmaster, a well-proven amp that has come back as a reissue model. It was still a dual-channel amp—instrument and microphone—but the newer 5E7 model had a fixed bias and a negative feedback loop, providing a louder, firmer, and cleaner tone. Most importantly, the single 15" speaker was replaced by three 10" speakers, making it very similar to the narrow-panel tweed Bassman, the granddaddy of all Marshall amps. This Bandmaster had three speakers instead of the Bassman’s four, and it delivered 25–30 watts instead of 40. It offered early breakup with a midrange-y, big and full tone.
For those not acquainted with tweed amps, the volume and EQ knobs behave differently than on silver- and black-panel Fender amps. The volume pot can act like a distortion control, while the EQ knobs control the volume, and many players I’ve talked to have not really unlocked this secret. This works because, in these circuits, the volume pot sits right before the preamp tube, which allows it to push the tube into full distortion. Since the EQ pots are located right after and are capable of reducing the volume, you’re able to distort the preamp at low volume settings.
“Things became more standardized in 1964 with the arrival of the black-panel AB763 Bandmaster, an amp I have worked on a lot and appreciate for its robustness, simplicity, and versatility.”
In 1960, a short-lived and rare Bandmaster dressed in brown tolex and a black faceplate appeared with the 5G7 circuit. From here on, all Bandmasters had the modern top-mounted chassis. With this circuit, the Bandmaster started to both look and sound more like a black-panel amp. It kept the 3x10" speakers but got a diode rectifier and bigger transformers resulting in a 45-watt output. Tremolo was introduced for the first time, and both channels were now intended for guitar.
The following year, a blonde 6G7 Bandmaster followed as a smaller amp head paired with a 1x12 extension cabinet. It had the timeless early blonde looks with cream tolex, brown faceplate, oxblood grill cloth, large Fender logo, and white knobs. But halfway into the blonde era, towards 1964, things turned strange and rather confusing. There were suddenly two 12" speakers, black knobs, a wheat-colored grill cloth, a more slim black-panel-style Fender logo, a black faceplate, and all in various combinations close to the transition into ’64.
Things became more standardized in 1964 with the arrival of the black-panel AB763 Bandmaster, an amp I have worked on a lot and appreciate for its robustness, simplicity, and versatility. It offers a pure, clean, scooped black-panel tone that’s somewhere between a Vibrolux Reverb and Pro Reverb, which share the medium-sized 125A6A output transformer and dual 6L6GC tubes. With its medium/high power and flexible 4-ohm output impedance, it can drive all kinds of speaker cabinets—as long as you stay between 2 and 8 ohms, you are safe.
For a short time in 1967–68, there was a transitional Bandmaster with aluminum trim and black-panel innards before the all-new silver-panel Bandmaster Reverb replaced it in 1968. The small-head cabinet had grown in size and, unfortunately, weight to accommodate the reverb tank. The amp got a 5U4GB rectifier tube along with a few general silver-panel changes to the circuit. Several silver-panel models existed with minor differences until a 70-watt beast version came along in 1977 with master volume.
To my own 1968 Bandmaster Reverb, I have done a few adjustments. First, I made a custom baffle to hold two 8" speakers. I installed a pair of WGS G8C speakers that fit perfectly on the baffle board without colliding with the reverb tank or transformers. Sometimes, I use only one of the 8" speakers for bedroom volume levels. Second, I reversed the bias circuitry to standard AB763 specs, making it easier to adjust bias correctly on both power tubes. If you are into sparkling clean and funky Strat sounds, you would love this little 2x8" combo.
