SOVIET SPARROW - Ultimate "Green Russian"

SOVIET SPARROW 

05/06/2026 - Two slots left of the first run! Be Quick 

The Soviet Sparrow takes the legendary Tall Font Green Russian Big Muff and pushes it further than most players ever imagined possible. Conceived as a no-compromise Custom Shop project, we left no stone unturned in our pursuit of the ultimate Green Russian which is now available as a standard production model.

Starting with a carefully selected transistor core, we've added clean blending, switchable clipping, adjustable mids, tone bypass, extra gain, impedance control and an independent boost stage to create one of the most versatile Russian-style fuzzes available today.

Want the massive low end and smooth sustain of a Green Russian? It's here. Need more cut, more gain, more output, or better compatibility with modern pickups? Soviet Sparrow delivers it all without sacrificing the character that made the original circuit legendary.

Last but not least, a fully independent Micro Amp-inspired boost stage sits after the fuzz circuit and can be used on its own or stacked with the fuzz. Perfect for lifting solos above the mix without altering your carefully dialled-in fuzz sound.

Perfect for: 

• Green Russian fans who want more control without losing authenticity.
• Bass players who want huge fuzz with retained low-end clarity.
• Alternative players stacking time-based effects into fuzz.
• Muff lovers that want "the Ultimate". 

Features:

• Clean blend, featuring a JFET OP-AMP buffering circuit for smooth blending
• Fully controllable Mids, with a 3 position "shift" and a pot to dial in the perfect amount, or dial back for stock "scooped" tones 
• Three-position clipping: stock silicon, red LED, and a unique schottky/silicon asymmetric mode for increased harmonic complexity 
• Input Sensitivity Control – optimise the fuzz response for vintage single coils, modern humbuckers or active pickups.
• Post-fuzz volume boosting gain stage on its own footswitch, based off the Micro Amp. Can be used independantly, for extra versatility
• Cream Control – introduces additional gain and saturation inspired by the famous Creamy Dreamer modification
• Tone Bypass option
• Internal "treble bleed" switch, which retains much more high end presence when the fuzz control is wound back, compared to traditional BM circuits 
• Soft touch, intelligent microcontroller controlled relay true bypass with bypass memory and momentary mode on each effect, fuzz and boost
• Beautiful matte "tank green" powdercoat finish, top mounted jacks and standard 9v DC power
• Soldered, wired and assembled completely by hand in Manchester, UK
