2B Booster
By Fulltone
A compact, transparent boost pedal with up to 20dB of gain and a diode-based Dynamics limiter.
About this pedal
The 2B packs the boost channel from Fulltone’s FD3 into a tiny 4.5” x 2.1” x 2.3” enclosure with rear-mounted jacks and a built-in JFET unity-gain buffer that stays active even when the pedal is off. A Dynamics knob adds a subtle germanium-diode limiter to tame transient spikes without squashing the tone.
