Doppel

Blue Colander Stompboxes, handcrafted by Juliusz in Poznan, Poland, creates high-end fuzz and effects pedals. The Doppel is a heavily modified Foxx Tone Machine circuit delivering thick, massive fuzz tones.

The Fuzz knob acts like a wah pedal, sweeping midrange with gentle bass cut at minimum and super thick response at maximum. Jolt control adds undistorted low end and extra grit. Tone is voiced for midrange boost to cut through mixes with optional aggressive rasp.

The octave switch engages raw, mean octave-up effects with adjustable intensity. Internal DIP switches allow mid-scooped voicings or Big Muff-style tones. Level provides massive output for amp pushing.

The thickest, heaviest octave fuzz variant of this classic circuit.
