A tribute to the classic MT10 MOSTORTION, the Mofetta features MOSFET clipping for authentic tones.
The Mofetta is a supercharged MOSTORTION, reborn and amplified that delivers the classic, amp-like overdrive, massive headroom, and versatile 3-band EQ that made the original so famous. Wampler wanted “more” and added a Texture Switch that introduces actual MOSFETs into the pedal’s overdrive section for a bolder, more articulate tone. The Mofetta preserves everything you love about the early ‘90s legend with a powerful new Wampler dimension.
Wampler Mofetta: A Modern Twist on the Mostortion MT10 Pedal Circuitry
The MT10 MOSTORTION
The original MT10 MOSTORTION was released in 1990 as part of a budget pedal series to meet the demand of a growing market. Despite the pedal’s “cheaper” qualities, guitarists began to take note of its amp-like low-gain tones, attributing them arguably incorrectly—to the onboard MOSFET Op-amps. Though the pedals were discontinued a couple of years later, used ones command insane prices today and are extremely hard to find. The Mofetta is Wampler’s way of bringing it all back and re-creating those singing tones while diving even further into the amp-like world of MOSFETs.
Musical, Responsive Overdrive
Paying tribute to a pedal called the MOSTORTION, it’s easy to assume the Mofetta would be a high-gain beast. But like its predecessor, it’s the circuit’s low-to-mid-gain voice that the original circuit is most known for. From edge-of-breakup to fat, vintage amp-style crunch, the Mofetta blooms with tube-like compression, always retaining its musical warmth. And with its high-headroom output, it easily pushes your amp or modeler into harmonically-rich breakup.
3-Band EQ
Part of what makes the Mofetta so versatile is its unique 3-band EQ. While many overdrives before 1990 relied on a simple tone knob, the idea of a dirt pedal like the MOSTORTION with bass, middle, and treble controls was darn near revolutionary. It lets you dial in the Mofetta for a full-range drive or achieve transparent grit that complements your clean tone. If you dial up the mids and treble a bit, you can even use it as a focused boost to push your amp’s breakup, or stacking with another gain pedal, tightening its response and enhancing its character.
Is it truly MOSFET?
One of the original MOSTORTION’s little-known “secrets” is that it doesn’t actually use MOSFETs for its overdrive. It uses a “MOSFET based op-amp”, but in reality uses clipping diodes to produce distortion. This left Brian thinking, “What if I built one that could actually use MOSFETs for the clipping, using multiple gain staging like a tube amp?” That’s what the Mofetta’s Texture feature is all about - it takes the pedal from smooth overdrive to fiery distortion with the flick of a Texture switch.
MOSFET clipping delivers a bolder, more articulate voice – louder, tighter, and slightly more aggressive than the original’s diode-driven dirt. While still not “Brutal High Gain” the Texture switch gives you a wider range of overdrive and even distortion that’s even more responsive to your playing dynamics. Is it better than the OG? That’s up to you, but for Wampler, it’s what the MOSTORTION was always meant to be.
The secret is out on the original MS10 MOSTORTION pedals. Their blend of responsive, amp-like gain and flexible EQ make them some of the most elusive yet sought-after dirt pedals out there. With the Wampler Mofetta you get that same tone and performance, now with a pure MOSFET enabled-version of the famed original.

This late-’90s Masterbilt was made to mimic the feeling and look of vintage luxury.
Some guitars just feel expensive. Not in an “I shouldn't be touching this, lest I scratch it” way so much as simply exuding luxury. Maybe it’s the flawless ebony fretboard, making gliding up and down the neck feel like ice skating. Or perhaps it’s the slim, ’60s-style neck shape which felt instantly comfortable in my small hands. It may have something to do with the sumptuously low 2/32" action at the 12th fret, requiring hardly any effort to play.
Makes sense, considering this guitar’s origin story. Mac Yasuda was born in Nishinomiya, Japan. At 15, he discovered the music of Hank Snow and fell in love with country music and the guitar itself. He stole a classical guitar from his cousin (“He never played it,” said Yasuda) and started a band with his friends. Yasuda traveled to the States in the ’70s and after picking up his first vintage guitar from a pawn shop, he was hooked. He began scoping out gear for his friends, which eventually grew into a shop called Mac’s Guitar Gallery in Kobe, Japan. By the ’90s, he estimated he had owned between 4,000 and 5,000 instruments, and his collection was valued at $3 million. He has authored several books about vintage guitars and is widely considered one of the world's preeminent authorities on the subject.
Yasuda is also an accomplished musician. While in Nashville in the ’80s—perhaps for one of the half-dozen times he’s performed on theGrand Ole Opry—he met Greg Rich, an instrument designer who was then head of Gibson’s banjo division. Yasuda enlisted Greg Rich and another guitar maker named Mark Taylor to produce a line of high-quality, vintage-style instruments under the name Masterbilt. “Vintage guitars are fine, but they're limited,” said Yasuda at the time. His Masterbilt guitars would give us mere mortals the chance to get a taste of the luxurious feel of a fine vintage instrument. Masterbilt debuted at NAMM in 1997, and it’s still unknown how many guitars were actually produced. The trademark of the Masterbilt name was cancelled in 2005 and has since been used by other brands, like Epiphone.
“Some folks think anything from the ’80s or before is vintage, but perhaps the fact that time has continued to march on should be factored in.”
Fanny's House of Music believes this guitar to be an early prototype, one of six ever made. Three were sunburst and three were natural. Playing it feels like playing any fine vintage 335; funny when you consider that at 27 years old, some would consider this Masterbilt vintage itself. The notion of what is considered truly “vintage” is hotly debated on Reddit every few months. Some folks think anything from the ’80s or before is vintage, but perhaps the fact that time has continued to march on should be factored in. Some guitars from the ’80s are now 45 years old! We consider guitars from the ’90s to be vintage at this point, so this 1998 Masterbilt prototype fits right in.
This Masterbilt is now 27 years old. In your books, does that make it a “vintage” guitar?

It’s a good example of how history and passion can intersect to create something special. This guitar tells a story of dedication to quality and an appreciation for the feel of a well-made instrument. Whether or not a 27-year-old guitar qualifies as “vintage” may be up for debate, but the magic in this guitar definitely isn’t. If you’re ever in Nashville, stop by Fanny’s and take it for a spin. You might find yourself feeling a bit like I felt after my unexpected ride in a Jaguar: getting a glimpse into the world of understated elegance, where refinement isn't about flash but about experiencing something crafted to near perfection.
