Fuzz drives the signal into extreme clipping, often flattening the waveform and generating a thick spectrum of harmonics. Transistor type, bias, input loading and tone filtering create markedly different responses, from loose and velvety to gated, spluttering or octave-rich. Some circuits interact strongly with pickup impedance and guitar volume, while others include buffers or blends for a more consistent response.
Connects input directly to output through mechanical or relay switching when the effect is off, removing the active circuit from the audio path. It avoids buffer colour but leaves cable capacitance and switching design to influence high-frequency loss and possible switching noise.
