JHS Pedals 539090 Operating instructions

OVERDRIVE PREAMP

JHS Overdrive Preamp is a faithful recreation of an extremely

rare (read: practically unknown) rst version of the DOD 250

Overdrive Preamp. If you love the 250 and are familiar with the

legendary Gray Box and Yellow Box versions, this is a must-

have addition to your collection. The JHS Overdrive Preamp is

a powerful tone shaping tool that can be used as a solo boost,

always on preamp, transparent overdrive or distortion. No

matter the musical genre or which amps or pedals you have in

your chain, the Overdrive Preamp is the pedal for you.

CONTROLS

LEVEL - “Level” adjusts the overall output of the circuit and lets you cut or boost the signal.

GAIN - “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).

POWER - Can be powered between +9 to +18 DCV center negative. Do not use more than +18

DCV. Your warranty will be voided. 5mA current consumption.

DOD IS A REGISTERED TRADEMARK. THE JHS PEDALS OVERDRIVE / PREAMP IS
