Diamond Comp/EQ Compressor and Equalizer Pedal

A classic compressor with modern architecture, Diamond's "yellow box" pedal offers silky-smooth optical compression and a hi-fi-inspired tilt equalizer.

There are few compressors that are more sought after than the yellow box Diamond.

This next-gen compressor maintains the classic circuit architecture while increasing range and functionality. The EQ section allows you to sculpt your tone in the same box that squashes it (that's a good thing). Furthermore, the attack switch allows you to go from the signature ultra-snappy Diamond comp style all the way to softer transparent compression.

Rather than mess with perfection, the Diamond Comp/EQ augments the original yellow box design with a Mids boost/cut control, Attack switch, custom spec'd, US made opto-isolators and modern, quiet switching.

Combining silky smooth, natural optical compression with Diamond's signature hi-fi inspired, centre-detent active tilt EQ and Mid boost/cut control, the Comp/EQ is a mastering solution for your effects chain....one you might never turn off.

For the modern pedal-user's needs. Space saving design, without any loss of quality. Complete with all analog, Burr-Brown audio path, top-mounted jacks, 9-18VDC operation and relay based true bypass switching.
