“Evil Green” Boomster mk.2

Clean boost
The Level control provides up to 16 dB of clean boost.
At its minimum setting, the active booster sits at unity gain.

Three voicings

• High-cut attenuates the top end; the amount can be set with an internal trimmer.
• Full-range keeps the response flat and open.

Mid-boost adds focused midrange; the amount can be set with a second internal trimmer.

Selectable buffer
Internal DIP switches select true or buffered bypass.
In buffered mode, the OPA2132 circuit restores frequencies lost through long cable and pedal runs without adding brittle highs or changing the
instrument's feel.

Expression and switching
Connect a standard passive 10 kΩ expression pedal to use the Boomster mk.2 as a travelling volume pedal.
The footswitch supports both momentary and latching operation.
