JHS Overdrive Preamp Guitar Effects Pedal

Description

 

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. 

The internals featured a floating/loose hand-etched PCB and the same DOD 250 circuit, but with a few changes. The internal parts dated as early as 1972 and, according to David, were harvested from old radios and electronics he scavenged when he started building his first effects. 

Features:

  • Level Controls - Adjusts the overall output of the circuit and lets you cut or boost the signal. 
  • Gain - 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. 
  • Slider - This slider switch allows you to explore two variations within the V1 clipping arrangements. The slide switch DOWN replicates the clipping from the earliest version ever found (this mode is the most distorted and saturated of the two). The slide switch UP uses the clipping arrangement found in a later serial number (this mode is a bit more open, louder and more clear). 
  • Can be powered between +9 to +18 DCV centre negative. Do not use more than +18 DCV.  
  • 5mA current consumption.
