Boomster mk2
High-fidelity buffer and 16dB clean boost with three voicings. Expression pedal input for volume swells.
Jam Pedals designed the Boomster mk2 as a high-fidelity front-end utility: buffer, clean boost, and volume pedal in one. Texas Instruments OPA2132 chips provide transparent amplification with up to 16dB of gain available.
The three-position voicing switch tailors response: top position rolls off high end (adjustable via internal trimmer), middle position stays flat and full-range, bottom position adds mids (also trimmer-adjustable). Selectable true or buffered bypass lets you place it where it makes most sense on your board.
Level controls boost amount. Expression pedal input (passive 10kΩ) enables volume swells—useful for violining effects or hands-free level control. Momentary or latching footswitch operation adds flexibility. Wide power range (9-18V) lets you dial in headroom to taste.
