Fulltone Fat-Boost FB-3 Overdrive Pedal, Used, with Original Box.

The Fulltone Fat-Boost FB-3 is a legendary overdrive pedal that combines transparent boost and natural overdrive in a compact, road-tested design. This used unit delivers the warmth and musicality that have made Fulltone a favorite among discerning guitarists for decades.

Known for its responsive, touch-sensitive overdrive that respects your amp's character while adding sustain and harmonic richness, the FB-3 excels at pushing clean tones into smooth breakup or stacking with other drives for enhanced complexity. The integrated boost stage lets you add punch and presence without losing definition.

Built to withstand the rigors of the stage, this pedal features true bypass switching and robust construction. In used condition, it carries the patina of a working musician's rig—battle-tested and ready to inspire.

Perfect for blues, rock, and alternative players seeking organic, articulate overdrive with vintage soul

The Fulltone Fat-Boost FB-3 is a discrete, Class-A, Field-Effect Transistor (FET) boost and preamp pedal.
