Diamond Pedals Comp/EQ

The Legendary Yellow Box, Reimagined

There are few compressors in the pedal world more sought-after than the iconic "yellow box" Diamond Compressor. The next-generation Diamond Comp/EQ maintains that classic circuit architecture while drastically increasing its range and functionality. This isn't just a compressor; it's an always-on tone sweetener that masters your signal chain.

By combining silky smooth, natural optical compression with an expanded, hi-fi-inspired EQ section, you can now squash and sculpt your tone inside the exact same box.

Signature Optical Compression

Rather than mess with perfection, we augmented the original design. The Comp/EQ features custom-spec'd opto-isolators that deliver the organic, highly musical compression Diamond is famous for. An added Attack switch allows you to seamlessly toggle between the signature ultra-snappy Diamond compression style and a softer, highly transparent compression that glues your tone together without sacrificing dynamics.

Pedalboard Mastering & Tone Sculpting

The new active EQ section gives you studio-grade mastering tools directly at your feet:

• Active Tilt EQ: Our signature centre-detent Tilt EQ acts as a sonic see-saw (Fulcrum Frequency: 800 Hz +/- 6 dB). Darken bright amps or add sparkle to muddy pickups with a single turn.
• Mid Boost/Cut Control: A highly requested feature, the new Mids control (Center Frequency: 800 Hz +/- 10 dB) allows you to push your signal forward for solos or scoop it out for pristine clean rhythms.

The New Standard in Pedal Design

Engineered for the modern pedal user, the Comp/EQ delivers an all-analog, Burr-Brown audio path housed in a compact, space-saving enclosure without any loss of audio quality. Complete with modern quiet switching, top-mounted jacks, and high-headroom 9-18VDC operation, it’s built to be the anchor of any professional touring or studio rig.
