The JHS Smiley Pedal is part of the Legends of Fuzz Series, which replicate classic and historic fuzz pedal circuits, and put them in a wedge-shaped black metal casing with vintage-style knobs to give a classic old school look. This pedal replicates the circuit of the classic 1969 Fuzz Face pedal used by musicians such as Jimi Hendrix, Eric Clapton, David Gilmour and Jack White, providing an aggressive bite, blistering sustain and vintage character. This is great for anyone who wants the classic fuzz tones in a more reliable, affordable pedal.The JHS Smiley Pedal is extremely easy to use. It has just two control knobs - Volume and Fuzz but is packed full of vintage fuzz flavours. When you turn down the Volume, it delivers a clean crunchy tone, and turning it up provides a biting low end and meaty midrange. Theres also a red Mode button on the side which delivers full-on high gain and gated fuzz tones, making this quite a versatile pedal.It can run on a 9v DC power supply or 9v battery
