Grimrobe

Blue Colander Stompboxes, handcrafted by Juliusz in Poznan, Poland, creates high-end fuzz and effects pedals. The Grimrobe is their most formidable pedal, featuring two massively evolved Rat-style OpAmp gain stages.

Both Hard and Soft Clipping can run in parallel, controlled by Limit and Comp knobs. The Harmonics control shapes output character including overblown tones, octave distortion, and octave fuzz textures. Two independent gain stages (OP7 and LM386) have separate footswitches.

Controls include Volume, High EQ, Low EQ, Voice switch, plus independent Distortion and More stage footswitches. The circuit has evolved far beyond its Rat roots into something entirely new.

For extreme distortion enthusiasts seeking cascaded crushing tones with extensive tone-shaping.
