Mad Professor Ruby Red Booster, designed by Björn Juhl (BJF Design) in Finland.
Two boosts in one pedal: a treble booster for that classic British lead bite, and a clean boost with up to about 40 dB of gain that can push your amp into overdrive. Use them together for anything from a subtle lift to a full-on cranked-amp lead tone. There is also an internal switchable buffer that helps keep your top end intact with long cable runs or big pedalboards.

Controls: Master, Treble, Boost

Condition: Very Good. Fully tested and working. Clean top graphics and solid jacks and footswitch. Light handling marks on the enclosure and a couple of small paint chips on the bottom plate near the screws (see photos).
