A good preamp pedal is like a Swiss-army knife. It can be used for many things and is typically always on. A great overdrive can be the same way. The JHS Overdrive Preamp combines both of these things in their faithful recreation of the DOD 250 Preamp Overdrive pedal. Being huge fans of JHS we couldn’t wait to get our hands on this pedal and see what it can do.
FROM JHS:
The JHS Overdrive Preamp is a faithful replication of this unobtainable V1 of DOD’s 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. We’ve also added a slider switch to this production version, which wasn’t included with the original DOD 250. While researching the #75 “Big Box” pedal, I acquired a second early big-box unit that used a completely different clipping arrangement. It only seemed fair to offer this switch so that you could explore these two variations for yourself.
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. This is a must-have addition to any DOD collector’s lineup, or for anyone who's curious about how it all started.
The standard Overdrive / Preamp will be part of our normal JHS lineup. Buy yours today and experience the history of one of the greatest overdrive/preamp circuits ever made.
