Bringing together two staple effects in a single chassis, the Tech 21 Boost Fuzz is a well-constructed staple suitable for any rig. Packing the roaring vintage tone of germanium fuzz, the pedal features standard controls for level, tone, and drive along with a unique Sag knob that imparts a touch of that sweet dying voltage tone. Throw in a separate 21dB boost function that can operate independently or in tandem with the fuzz, and you've got a formidable effect on your hands.
