Featuring a diehard metal enclosure, dual-knob layout with controls for volume and bias, and hand-selected silicon transistors for a solid, aggressive bite, the MJM Guitar FX London Fuzz is a buzzed-out blast from the past. Affording a slew of textures from a smooth chop to a scathing attack controllable through the bias knob, this pedal captures the voicing of fan favorites from the '60s and '70s and plops them in one convenient box. Perfect for psychedelia, the London Fuzz is also a prime candidate for garage and punk.
