The circa 1991 Sovtek “Civil War” Big Muff (dubbed that because of its blue and gray chassis) used the same circuit as the “Tall Font Green Russian” Big Muff and our EHX Green Russian Big Muff! The new Sovtek Deluxe Big Muff expands on that big, wooly sound with the addition of the Deluxe Big Muff’s advanced controls while paying homage to the Civil War Big Muff aesthetic.

It’s all here in one integrated pedal. The Sovtek signature sound. The devastating low end, crisp highs and non-scooped mids, plus the advanced control of the Deluxe Big Muff in a single, completely integrated pedal.

We’ve kept the familiar Sustain, Tone and Volume knobs, and we’ve added a ton of extras from the Deluxe Big Muff for those who crave its deep sound shaping abilities.

  • MIDS EQ – Parametric MIDS EQ section with a selectable center frequency ranging from 310Hz to 5.0kHz, a level control with up to 10dB of boost or cut and a high/low Q switch that sets the resonance/bandwidth of the EQ
  • FOOTSWITCH for MIDS EQ – Dedicated on/off footswitch with status LED for the MIDS EQ circuit
  • GATE – Noise gate to remove unwanted hiss and hum
  • BLEND – Mix control for the dry and distorted signals. Enables bass players to retain their signal’s low end; also useful when layering in other distortion pedals
  • WICKER– With the switch up, high frequency bandwidth is opened up for a more pronounced attack. Switch down yields the traditional Green Russian sound.
  • EXPRESSION PEDAL INPUT – Sweeps the frequency of the MIDS EQ to create wah wah and cocked wah effects
  • TRUE BYPASS – Maintains signal path integrity in bypass mode
  • INTERNAL INPUT BUFFER SWITCH – An internal slide switch to engage a buffer on the Big Muff’s input circuit that increases the high end content of both the distorted and clean signal being blended in
  • MIDS EQ TRIM POTS – Three internal trim pots for adjusting (a) High Q bandwidth, (b) High Q output volume and (c) overall MIDS EQ output volume.
  • A fully integrated pedal that combines the “Civil War” / “Tall Font” Green Russian Big Muffs plus the Deluxe Big Muff Pi
  • Foot-switchable MIDS EQ section that delivers extensive sound shaping control
  • High Q / Low Q switch
  • Wicker switch to open up high frequency bandwidth
  • Noise Gate
  • Expression pedal input
  • True Bypass
  • 9-Volt battery included, also accepts optional EHX 9.6VDC-200mA power supply
  • Current Draw: 22mA @ 9VDC
  • Dimensions in inches: 4.75(w) x 5.75(l) x 2.5(h)
  • Dimensions in mm: 121(w) x 146(l) x 64(h)
  • VOLUME Knob – Works as a master volume control for the entire pedal
  • BLEND Knob – This mixes between the dry and distorted signals. Turn this knob fully counterclockwise for 100% dry signal and fully clockwise for 100% wet signal. Setting the BLEND knob to noon yields a 50/50 mix of dry/distorted signal.
  • TONE Knob – Provides a range of sounds from high treble to deep bass. As you turn the TONE knob clockwise, treble increases and bass decreases.
  • SUSTAIN Knob – As in the original Big Muff Pi, adjusts the amount of sustain and distortion
  • Wicker Switch – This feature is the same as the switch found on the Big Muff Pi with Tone Wicker. With the switch up, the wicker is engaged and high frequency bandwidth is opened up for a bright and clear top end and more pronounced attack. With the switch down, the effect is disengaged and the Big Muff circuit is back to stock.
  • GATE Knob – Turning GATE clockwise raises the Gate threshold requiring greater input amplitude to open the noise gate, allowing your notes to be heard and your instrument to pass through. Turn the GATE knob down all the way, to fully counter-clockwise, to disable the noise gate.
  • MIDS LEVEL Knob – When MIDS is engaged (LED near MIDS Footswitch is lit) the MIDS LEVEL knob either boosts or cuts up to +/- 10dB, at the frequency set by the FREQ knob located below it. Turn MIDS LEVEL clockwise from its center 12 o’clock position to boost the center frequency. To cut, turn MIDS LEVEL counter-clockwise from the 12 o’clock position. 
  • MIDS FREQ Knob – Sets the center frequency of the MIDS EQ circuit ranging from 310Hz to 5.0kHz. To hear the range of the MIDS FREQ knob, turn the MIDS LEVEL knob up past 3 o’clock, make sure MIDS is enabled (LED near MIDS Footswitch is lit), then play your instrument while turning the MIDS FREQ knob. 
  • The MIDS FREQ knob can be controlled by an external expression pedal or control voltage (CV). Connect the external device to the EXP jack on the input side of the Sovtek Deluxe Big Muff. The position of the MIDS FREQ knob sets the toe position of the expression pedal or maximum frequency for CV. 
  • MIDS Q Switch (HIGH/LOW) – The Q switch sets the resonance or bandwidth of the MIDS EQ. What this means is in LOW mode the EQ sounds broader or rounder and affects a larger range of frequencies; in HIGH mode the EQ sounds sharper or peakier and affects a narrow range of frequencies.
