The THD is an HM-2 inspired fuzz distortion pedal developed from the first pedal ever built by Dazatronyx. It is designed to deliver aggressive, saturated distortion tones with expanded control compared to the original circuit. The distortion control uses a dual-gang potentiometer that blends fuzz with compression and sustain. A germanium diode clipping stage is used for the final compression stage. The pedal features low and high frequency boost controls for tonal shaping. The THD is hand built using selected components for noise reduction and tonal consistency.
