Acorn Amplifiers F#%k Face

What's with the cheeky name and graphics on Acorn Amplifiers' F#%k Face? Long story short: In 1989, the Fleer baseball-card company "accidentally" printed a short-lived card featuring Bill Ripken (Hall of Famer Cal Jr.'s less-known brother), hoisting a bat with "Fuck Face" scrawled on its butt. Besides being funny, the tie-in is that F#%k Face is inspired by the famous round 2-knob fuzz favored by Hendrix, Gilmour, and Eric Johnson—only it ups its progenitor's gain ante with three stages of filth courtesy of three 2N3904 silicon transistors.
I tested F#%k Face with a Stratocaster equipped with Fender Custom Shop '69 pickups, a Gibson '57 Classic-loaded Les Paul, a Tele with Curtis Novak single-coils, and an Eastwood Sidejack Baritone with Novak JM-WR pickups. Amps included a 1976 Fender Vibrolux Reverb, a KT66-driven Sound City SC30, a 6973-driven Goodsell Valpreaux 30, and a Fender Rumble 200.
Often Fat, Always Nasty
Cutting to the question undoubtedly at the fore of your own face, yes, F#%k Face is nasty. In many respects it reminds me of the vintage-Mosrite-inspired Jordan Fuzztite—a silicon-transistor unit with a switchable high-gain mode that's been my go-to fuzz for years. Both units furnish buzzy, Velcro-y tones that are categorically not for the faint of heart. Put another way: If you're looking for sweetly singing Jimi leads, F#%k Face will do exactly as its name says.
Despite its lack of an EQ control, F#%k Face's tone profile shifts a bit, depending (primarily) on where its level knob is set. Unity gain tends to be anywhere from 10 o'clock to noon, and from there to about 2 o'clock, tones are more mid-dominant, while past 2 it becomes increasingly corpulent and low-mid heavy. In general, lower fuzz-knob settings are thin and spitty (I like the wasp-in-a-tin-can metaphor), while increasing gain past noon simultaneously smooths out the sound, focuses frequencies in the low and low-mid range, and introduces huge, frothing, effortlessly infinite steroidal cello sustain.
If you're looking for sweetly singing Jimi leads, F#%k Face will do exactly as its name says.
At higher gain settings, there were many times when F#%k Face's riotous rotundity felt a little too indistinct and same-y in any pickup position other than the bridge. This might lead one to surmise F#%k Face is for doomy folks. And at extreme settings, many will certainly miss the cushy attack dynamics you typically get from neck or middle pickups. But there's enough interactivity between the pedal's controls, and a decent enough ability to clean things up with guitar-volume tweaks, that you can still get some in-between flavors. A silver lining to this apparent "limitation" is that F#%k Face sounds very consistent from guitar to guitar, regardless of pickup type.
The Verdict
If you're a fuzz deviant like I am, F#%k Face offers a lot to be intrigued by—especially in a stomp category where staid often seems to be the MO. My main wish while playing F#%k Face was that tone shifts were either a little more perceptible or more responsive to volume-knob tweaks at high gain settings. I loved that F#%k Face could make a Les Paul sound like an overloaded arcing Jacob's ladder. But sometimes the gain was so thick it was difficult to predict, rhythmically, how riffs or leads would come out the other end. (Granted, some might view that as a plus.) Interestingly, one of my favorite settings was fuzz at minimum and level at 3 or 4 o'clock, which—with my Tele volume down a tad and my Sound City SC30 dialed to a Vox-y recipe—yielded a responsive, bristlingly dynamic, and hyper-charged Kinks vibe.

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!
