Thanks for purchasing a Diamond J-Drive!

We hope you have as much fun playing guitar through this pedal as we did designing

and testing it. Our goal is to provide new twists on classic drive tone, and to make it

just plain fun to play. The J-Drive is a cool pedal - independently switchable clean boost

and overdrive functionality that lets you use the clean boost section as a lead gain stage

when the pedal is in overdrive.

Remember to protect your hearing and wear appropriate hearing protection when play-

ing loud...

Design Features

True bypass signal path

Dual function clean boost / lead boost as a separately switchable gain section

3-transistor discrete clean boost stage with high impedance JFET input, BJT gain and

class A output stage

Premium audio components, including 2% polypropylene capacitors and 1% metal ﬁlm

resistors.

Warmth control - replaces the traditional ﬁxed frequency cut/boost circuit with a variable

high-frequency cutoff ﬁlter coupled with variable low-frequency gain.
