Thanks for purchasing a Diamond Compressor! We hope you have as much fun playing guitar 

through this pedal as we did designing and testing it. Our goal is to provide a versatile ‘guitar 

channel’ – a dynamics and tone shaping tool to front-end your effects chain. 

Remember to protect your hearing and wear appropriate hearing protection when playing loud…

Design Features

Vactrol opto-isolator variable resistance path as used in high-end studio compressors for smooth 

attack and decay characteristics while preserving initial signal transients.

Post-compressor ‘tilt’ EQ provides a very musical tailoring of frequency response -  seamlessly 

transition from a darker jazz voicing to a bright jangle, with flat frequency response at the cen-

ter detent position.

Optimized gain staging and use of ultra low noise transistor and opamps in signal path for lowest 

possible noise and extended signal headroom.

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

Dual AC capacitive coupling paths for improved transient response.

Bi-color LED provides visual indication of depth of compression.

True bypass signal path.

Battery or standard negative tip 9V DC adapter operation, can be powered from 9 to 24 V nega-

tive tip.
