JHS Pedals Overdrive preamp
The JHS Overdrive Preamp is a faithful replication of this unobtainable V1 of DODs most loved pedal. The controls are simple. The Level control adjusts the overall output of the circuit and lets you cut or boost the signal. The level control of this version has been modified (corrected) from the original wiring of the #75 unit, giving this pedal much more volume on tap.
The Gain control adjusts the amount of gain inside the overdrive circuit. Turning up Gain creates more clipping as it pushes the op-amp and hard clipping into overdrive. Weve also added a slider switch to this production version, which wasnt included with the original DOD 250.
While researching the #75 Big Box pedal, I acquired a second early big-box unit which used a completely different clipping arrangement. It only seemed fair to offer this switch so that you could explore these two variations for yourself.
