INTRODUCTION
When we began work on the original Diamond Compressor back in 2004, our goal was to
build a versatile 'guitar channel' – a dynamics and tone shaping tool to front-end your
effects chain - much like the gain, compression and EQ channels used in traditional
recording studio mixers. Introduced at MusikMesse 2005 in Frankfurt, the Diamond
Compressor has found its way onto thousands of pedal boards worldwide - and our
sincere thanks to all those who have supported us over the years. Since introducing the
original comp, we've released a version tailored to the bass (the Bass Comp), as well as a
special 'audiophile' edition of the comp called the Comp SE. Through this time, we've
also had many requests for a more compact version of the original Diamond
Compressor... now introducing the Diamond Comp Jr!

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
center 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 tight tolerance PPS capacitors and metal film resistors.
• Top mounted jacks on a small enclosure for tight pedalboard layouts
• 9V battery power, with standard 9V negative tip adapter ready
• Bi-color LED provides visual indication of depth of compression and power
• true bypass operation
CONTROLS
It really doesn't get any simpler than the on/off footswitch and three controls:
!
ON/OFF switch: this switches the pedal between bypass and in-circuit operation. A green
color in the LED indicates that the pedal is on, while increasing levels of red mixed with
the green indicates increasing levels of compression on the guitar signal.
!
COMP: this controls the amount of compression to be applied to the guitar signal.
Backing it off all the way gives just a touch of compression on signal peaks, while
turning the control clockwise gives an increasing amount of signal 'squash'. The
compression threshold, the input signal level at which compression begins to take effect,
is sensitive to level variations like pickup output and players picking strength, so
certainly experiment with this control for your particular setup.
