The Rude Tech 3MuF-14 is a three-in-one Muff-style distortion/fuzz pedal that emulates three different Russian Big Muff circuits, Black, Green and Civil War, through a three-way toggle, and adds a built-in mid-focused overdrive with its own footswitch1. It is aimed at players who want several flavors of the Russian Big Muff without owning several pedals.
Three Russian Big Muff circuits in one pedal
The Russian Big Muffs were a simple circuit with a simple three-knob layout that is highly tweakable, which is why boutique builders and pedal modders have long gravitated to them3. At its core, the Big Muff design is cascaded overdrive sections that go through clipping diodes with filtering, as Kit Rae's Big Muff history explains4. The Sovtek-era Russian versions of that circuit have their own following: Wren and Cuff, another Muff-style builder, bases pedals on vintage Sovtek-era Big Muffs, calling them among a builder's favorites5.
The 3MuF-14 gathers three of those Sovtek circuits in one box. Premier Guitar's Blair White described the approach as "Taking three well-loved and legendary Sovtek Big Muff circuits, the 'Civil War,' 'Green Russian,' and 'Black Russian'" and putting them in a single pedal2. A three-way toggle selects between them1.
The fourth sound: tone bypass
Beyond the three Muff selections, the pedal offers a fourth sound achieved by entirely bypassing the "Version" circuit. According to Delicious Audio's Paolo De Gregorio, this produces a tone that keeps the Big Muff character without the classic mid scoop1. For players who find a Big Muff's scooped mids get lost in a band mix, that bypassed setting keeps the fuzz texture while leaving the mids in place.
Controls and footswitches
The main fuzz side carries the familiar Big Muff layout, with additions:
- Volume, tone, and sustain dials, the standard Big Muff three-knob arrangement2
- Toggles for tone and Muff-style selection, the latter choosing between Black, Green, and Civil War12
- Trim, a separate gain knob for the built-in overdrive1
- Second footswitch, which triggers the overdrive on and off independently1
The overdrive itself is mid-focused, and Premier Guitar noted that it comes "with its own footswitch, so your sweet riffs aren't left out of the fun"2. That makes the 3MuF-14 effectively two pedals in one enclosure: a selectable Russian Muff fuzz and a drive channel you can stack with it or use alone.
Delicious Audio described the front panel as busy: "the 3MuF-14 might as well be a control panel ripped out of the cockpit of a MiG jet." With two toggles, four knobs and two footswitches, it asks more of the player than a stock three-knob Big Muff. \- Paolo De Gregorio, Delicious Audio, 14 January 20211
Build and price
The pedal is built heavy: Delicious Audio describes heavy-duty construction with a metal faceplate and aluminum toggle guards1. Premier Guitar's May 2025 roundup of modern fuzz pedals lists the 3MuF-14 Distortion/Fuzz at $255 street2.
What reviewers said
In Premier Guitar's review, Blair White wrote that "Jesse Rhew, of Rude Tech in Nashville, really knocked this one out of the park," and added that the pedal, with its volume, tone, and sustain dials plus toggles for tone and Muff-style selection, "should be on your watch" list2. Delicious Audio's early coverage, from January 2021, framed it as a practical consolidation: three Russian fuzz circuits, a tone-bypass option, and a mids-friendly overdrive in one enclosure1.

Questions
Which Big Muffs does the Rude Tech 3MuF-14 cover?
The 3MuF-14 emulates three Russian Big Muff circuits through a three-way toggle: the Black Russian, the Green Russian, and the Civil War. Premier Guitar's Blair White described these as three well-loved and legendary Sovtek Big Muff circuits. A fourth sound bypasses the version circuit entirely, keeping the Big Muff character without the classic mid scoop.
What is the fourth sound on the 3MuF-14?
Besides the three selectable Muff circuits, the pedal offers a fourth sound achieved by entirely bypassing the version circuit. According to Delicious Audio's Paolo De Gregorio, this produces a tone that keeps the Big Muff character without the classic mid scoop, so mids stay in the signal.
Does the Rude Tech 3MuF-14 have an overdrive?
Yes. The 3MuF-14 adds a mid-focused drive circuit with its own footswitch, so it works as a fuzz and an overdrive in one box. The overdrive has a separate gain knob called Trim, and it can be triggered via the second footswitch independently of the fuzz section.
What does the Trim knob do on the 3MuF-14?
Trim is the gain knob for the pedal's built-in overdrive. Delicious Audio notes that this overdrive has a separate gain knob called Trim, letting you set how much drive the mid-focused circuit produces apart from the fuzz side's sustain control.
Who makes the Rude Tech 3MuF-14?
The 3MuF-14 is made by Rude Tech, based in Nashville. Premier Guitar's review credits Jesse Rhew of Rude Tech with the design, saying he really knocked this one out of the park.
How much does the Rude Tech 3MuF-14 cost?
Premier Guitar's May 2025 review lists the Rude Tech 3MuF-14 Distortion/Fuzz at $255 street.
