Jhs Overdrive Preamp

The JHS Overdrive Preamp is a replication of the unobtainable V1 of DOD’s most loved pedal, the famous 250.
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.
Also added a slider switch to this production version, which wasn’t included with the original DOD 250.
This "Big Box V1" DOD 250 circuit definitely feels like a 250, but with a few changes : more gain/grit overall and more unique low/mids.
