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.
