The Boost/EQ concept began in the early 2000s with a request for a "compression less"
version of the Diamond Compressor—combining a clean boost circuit with the
Compressor’s Tilt EQ.

Nearly 20 years later, we've re-imagined this idea on the same platform as the Comp/EQ.
Introducing the next-generation Diamond Boost/EQ. This versatile, low-noise pedal delivers
a punchy, dynamic sound molded for any scenario.

With the lively, high-fidelity gain stages of the Comp/EQ, the Boost/EQ offers plenty of
punch while maintaining clarity and transparency. The Tilt and Mid controls give you
complete freedom to sculpt your tone. Need more sparkle? Dial it in with the Tilt knob.
Looking for a midrange boost to cut through your solos? The Mid control has you covered.
Want to make your Marshall tone a bit more Fender-esque? It’s all possible with the
Boost/EQ.

Additionally, the Boost/EQ features a second mode that provides a low-gain overdrive—
transparent, yet full of character. This makes the Boost/EQ the ultimate Swiss Army knife
for your pedalboard, combining clean boost, tone shaping, and overdrive into one powerful
and versatile pedal.
