Electro-Harmonix Sovtek Deluxe Big Muff Pi Distortion/Sustainer Effects Pedal

The Electro-Harmonix Sovtek Deluxe Big Muff Pi combines the Green Russian Big Muff’s signature tones — the devastating low end, crisp highs and non-scooped mids, with the advanced control of the Deluxe Big Muff in a single, completely integrated pedal.

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

Here’s what the Sovtek Deluxe Big Muff Pi provides:
1. 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
2. FOOTSWITCH for MIDS EQ – Dedicated on/off footswitch with status LED for the MIDS EQ circuit
3. GATE – Noise gate to remove unwanted hiss and hum
4. 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
5. WICKER– With the switch up, high frequency bandwidth is opened up for a more pronounced attack. Switch down yields the traditional Green Russian sound.
6. EXPRESSION PEDAL INPUT – Sweeps the frequency of the MIDS EQ to create wah wah and cocked wah effects
7. TRUE BYPASS – Maintains signal path integrity in bypass mode
8. 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
9. 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.
