The JHS Pedals Overdrive Preamp is a faithful replication of the first version ("Big Box V1") of DOD's most loved pedal, the Overdrive/Preamp (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, giving this pedal much more volume on tap. The Gain control adjusts the amount of gain inside the overdrive circuit. Turning up the Gain control creates more clipping as it pushes the op-amp and hard clipping into overdrive. JHS Pedals also added a slider switch, which wasn't included with the original DOD 250. While researching the original pedal, JHS Pedals acquired a second early big-box unit which used a completely different clipping arrangement. The JHS Pedals Overdrive Preamp features more gain/grit overall and more unique low/mids than the later versions of the DOD 250.
