The Valco-produced English Tonemaster is a rare, lap-steel-inspired gem from the 1950s—when genres and guitar design were fluid.
The 1950s were a peculiar time for the electric guitar. Innovators, designers, and tinkerers were pushing the boundaries of the instrument, while musicians were experimenting with various playing techniques and sounds. There was an evolution of sorts (or de-evolution, depending on your slant) from solidbody “sit-down” guitars, like pedal and lap steels, to “stand-up” or “upright” solidbody electrics. If you look at an early Fender catalog—let’s say from 1953—you’ll see the Telecaster (and Esquire), the Precision Bass, and then a whole bunch of steel guitars. There was a shift underway, and many manufacturers began to blur the lines of what a guitar should look, sound, and play like.
So, let’s examine a guitar from the mid-’50s that had a bit of a personality crisis, born out of the American Valco Company, which also suffered from fits of mania … but in the best ways. I’ve spoken about the company a lot in this column, but to summarize: Chicago-based Valco made instruments under several different brand names, including Supro, Airline, National, and Oahu. They were a quirky organization with a lot of interesting ideas and build styles. One of Valco’s lesser-known brands was English Electronics, which was sold out of a music store/studio in Lansing, Michigan.
Here's a look at the distinctive strings-through bridge pickup.
The English Electronics Tonemaster is a perfect example of this transitional era in instrument production. Half lap steel and half electric guitar, this model was meant to appeal to all sorts of players and was totally unique. There was a similar and more common model in the Supro-branded lineup, the Supro Sixty, which made its appearance in the 1955 catalog and was among the first standard Supro electrics to feature a lap-steel pickup. Both the Supro Sixty and the English Electronics Tonemaster came equipped with similar single volume and tone knobs as well as that same pickup, whose design allowed for the strings to pass through the middle. In the Supro catalog, the pickup was described this way: “The dynamic ‘locked-power’ unit design provides the sensitive extra responsive punch that Western ‘take-off’ players are always looking for—each string has its own individual adjustment to assure perfect string output balance.”
The English Tonemaster logo on the headstock is straight out of 1950s industrial design.
That lap-steel pickup in the bridge position made for a real treble-laden adventure. I love the “take-off” tone descriptor used in the catalog, because when one of these is dialed in, the guitar surely does have a sharp attack. The Supro Sixty was renamed the 1560S Ozark around 1958, but it kept the unique lap-steel unit at the bridge. The Supro Sixty/Ozark was cool and had a good five-year run. But the lesser-known, way cooler, and way rarer, cousin the Tonemaster was the king-daddy!
Half lap steel and half electric guitar, this model was meant to appeal to all sorts of players and was totally unique for its time.
I’ve never seen an English Electronics catalog and I don’t know anything about the owner, Norman English, but I do know that one reason this guitar was unique in the Valco lineup was that it sported not one, but two, pickups: that lap-steel pickup at the bridge and a proprietary Valco unit at the neck. That neck pickup, which is often confused for a humbucker, is actually an in-house designed, patented single-coil with some amazing tones to offer. With these two units, the sound of the Tonemaster was wide-ranging, going from nasally and thin at the bridge to thick and loud at the neck. The Tonemaster also included a pickup switch, but the one on mine was more like a blender without a detent for each position. I’m not sure if my switch was broken or if it worked as intended. Thankfully, Valco used a serial number plate, often found on the back of the headstock, and that number put this guitar in the 1957 range.
The bridge pickup cover is on in this shot. The neck pickup is a single-coil, despite appearances.
Stuff like this makes me ponder the era when electric guitars and lap steels were transitioning to different styles of music and playability, and there weren’t many definitive lines between country & Western, rock ’n’ roll, swing, and rockabilly. Things were blurred and woven into one another, as they are in this guitar!

The Schaffer Replica® - BASS-X
After introducing the Schaffer Replica Storm low end legends like Rudy Sarzo, Billy Sheehan, and Pino Paladino discovered it to be equally amazing on bass. Based upon their input we made a few minor changes to this beloved circuit to make it more conducive to higher amplitude and lower frequencies. To our loyal bassists who have waited so patiently, we proudly introduce The Schaffer Replica - BASS-X.
Vintage-style reverb, tremolo, and vibrato sounds abound in a 3-in-1 stomp that might be the only box you need.
Here’s part two of our look under the hood of the funky rhythm guitar master’s signature 6-string.
Hello and welcome back to Mod Garage. In this edition, we’re continuing our journey through the Fender Cory Wong Stratocaster wiring, bringing it all together.In the previous installment, the last feature on the funky 6-stringer’s signature axe that we discussed was the master volume pot and the corresponding treble-bleed circuit. Now, let’s continue with this guitar’s very special configuration of the tone pots.
Tone pot with Fender Greasebucket tone system:
This 250k tone pot is a standard CTS pot with a 90/10 audio taper found in all U.S.-built Fender guitars. The Cory Wong guitar uses the Fender Greasebucket system, which is added to the pot as a ready-to-solder PCB. The Greasebucket PCB is also available individually from Fender (part #7713546000), though you can use conventional electronic parts for this.
Fender introduced this feature in 2005 on some of the Highway One models and some assorted Custom Shop Strats. The Greasebucket name (which is a registered Fender trademark, by the way) is my favorite of Fender’s marketing names, but don’t let it fool you: Your tone will get cleaner with this modification, not greasy and dirty.
According to Fender, the Greasebucket tone circuit reduces high frequencies without adding bass as the tone knob is turned down. Don’t let that description confuse you. A standard Strat tone control does not add any bass frequencies! As you already know, with a passive system you can’t add anything that isn’t already there. You can reshape the tone by deemphasizing certain frequencies and making others more prominent. Removing highs makes lows more apparent and vice versa. In addition, the use of inductors (which is how a passive pickup behaves in a guitar circuit) and capacitors can create resonant peaks and valleys (band-passes and notches), further coloring the overall tone.

This type of band-pass filter only allows certain frequencies to pass through, while others are blocked. The standard tone circuit in a Strat is called a variable low-pass filter (or a treble-cut filter), which only allows the low frequencies to pass through while the high frequencies get sent to ground via the tone cap.
The Greasebucket’s band-pass filter is a combination of a high-pass and a low-pass filter. This is supposed to cut high frequencies without “adding” bass, which has mostly to do with the resistor in series with the pot. That resistor means the control will never get to zero. You can get a similar effect by simply not turning the Strat’s standard tone control all the way down. (The additional cap on the wiper of the Greasebucket circuit complicates things a bit, though; together with the pickups it forms an RLC circuit, but I really don’t want to get into that here.)
The standard Fender Greasebucket tone system is used in the Cory Wong Strat, which includes a 0.1 μF cap and a 0.022 uF cap, along with a 4.7k-ohm resistor in series. These are the values used on the PCB, and without the PCB it looks like the illustration at the top of this column.
Push-push tone pot with preset overwriting function:
The lower tone pot assigned to the bridge pickup is a 250k audio push-push pot with a DPDT switch. The switch is used to engage a preset sound by overwriting the 5-way pickup-selector switch, no matter what switching position it is in. The preset functionality has a very long tradition in the house of Fender, dating back to the early ’50s, when Leo Fender designed a preset bass sound on position 3 (where the typical neck position is on a modern guitar) of the Broadcaster (and later the Telecaster) circuit. Wong loves the middle-and-neck-in-parallel pickup combination, so that’s the preset sound his push-push tone pot is wired for.
The neck pickup has a dedicated tone control while the middle pickup doesn’t, which is also another interesting feature. This means that when you hit the push-push switch, you will engage the neck and middle pickup together in parallel, no matter what you have dialed in on the 5-way switch. Hit the push-push switch again, and the 5-way switch is back to its normal functionality. Instead of a push-push pot, you can naturally use a push-pull pot or a DPDT toggle switch in combination with a normal 250k audio pot.
Here we go for the wiring. For a much clearer visualization, I used the international symbol for ground wherever possible instead of drawing another black wire, because we already have a ton of crossing wires in this drawing. I also simplified the treble-bleed circuit to keep things clearer; you’ll find the architecture of it with the correct values in the previous column.

Wow, this really is a personalized signature guitar down to the bone, and Wong used his opportunity to create a unique instrument. Often, signature instruments deliver custom colors or very small aesthetic or functional details, so the Cory Wong Stratocaster really stands out.
That’s it! In our next column, we will continue our Stratocaster journey in the 70th year of this guitar by having a look at the famous Rory Gallagher Stratocaster, so stay tuned!
Until then ... keep on modding!
