Model T Power Amp Distortion

Model T inspired power amp circuit delivers crushing, saturated distortion with massive low-end response. This mode emulates the sound of a tube power amp pushed into clipping: thick, heavy, and dynamic. The circuit responds to playing dynamics and guitar volume, cleaning up when you back off and slamming forward when you dig in. Designed specifically for bass and downtuned guitars, the Model T mode retains low-end clarity while adding harmonic richness and compression. Ideal for doom, stoner, and heavy rock tones.

Silicon and New Old Stock Germanium Transistors

A combination of silicon & NOS germanium transistors in Darlington configuration create aggressive octave-up fuzz with synthetic edge and gated character. The octave mode generates upper harmonic content similar to classic octave fuzzes, producing everything from smooth sustained leads to sputtering, collapsing textures. High-quality JFET input buffer with 1M input impedance allows Rabbit X to work anywhere in your signal chain, not just first position. Compatible with active pickups and buffered pedals, fitting modern rig requirements without compromising fuzz response. A transformer network bridges the buffer and fuzz circuit, preserving dynamic interaction while eliminating impedance issues.

Switch Between the Cranked Vintage Model T Amp and Octave Fuzz in One Box

A two-position toggle switch routes between Model T distortion and octave fuzz modes. No stacking, no blending - each mode operates independently with its own distinct voice and gain structure. Switch between crushing power amp saturation for rhythm work and octave fuzz for leads and experimental tones. Simple, direct switching allows instant tone changes without complicated controls or menu diving. One pedal, two completely different distortion characters.
