Unleash Your Tone

The original Boost/EQ concept began in the early 2000s as a highly requested "compression-less" version of the iconic Diamond Compressor—combining a pristine clean boost circuit with Diamond's acclaimed Tilt EQ. Nearly two decades later, we’ve reimagined this classic on the high-fidelity platform of our modern Comp/EQ.

Introducing the next-generation Diamond Pedals Boost/EQ. Built to be the ultimate Swiss Army knife for your pedalboard, this versatile, low-noise effects pedal combines clean boost, precise tone shaping, and a character-rich overdrive into one powerful, dynamic enclosure.

Sculpt Your Sound with Precision EQ

Utilizing the lively, high-fidelity gain stages of the Comp/EQ, the Boost/EQ gives you complete freedom to sculpt your tone while maintaining absolute clarity.

• Tilt EQ Control: Dial in the perfect treble/bass balance. Need more sparkle? Pivot to the right. Want a warmer, fatter tone? Pivot to the left. (Fulcrum Frequency: 800 Hz +/- 6 dB)
• Mid EQ Control: Cut through the mix or completely re-voice your amp. Push the mids for soaring solos, or scoop them out to make your British-voiced amp sound remarkably American. (Center Frequency: 800 Hz +/- 10 dB)

Two Distinct Operating Modes: Boost & Overdrive

Easily toggle between two unique clipping options to match your exact rig requirements:

• Boost Mode (Up): Delivers up to +20 dB of clean boost with massive headroom. Use it at the end of your chain for a pure volume jump, or place it in front of your drives and tube amps to slam the front end for natural saturation and endless sustain.
• OD Mode (Down): Modifies the pedal's gain structure and introduces soft-clipping diodes. This mode provides a smooth, transparent, and highly musical low-to-mid gain overdrive that reacts dynamically to your picking hand.

Designed for Real-World Use

Like all Diamond pedals, the Boost/EQ is meticulously engineered for modern pedalboards. Featuring top-mounted jacks, soft-touch relay true bypass switching, and standard 9-18V power capabilities, it's ready for any studio session or touring rig.
