Delivering the deep and textured tone that Aguilar bass pedals are famous for, the Fuzzistor provides classic silicon transistor distortion. The Fuzzistor allows for complete control over the BLEND of the clean and Fuzz sound, the amount of FUZZ from subtle to crushing, LEVEL for gain matching, and TONE which is a tilt EQ that changes the harmonic structure of the Fuzz from booming to gnarly. *Pedal powered by universal 9-volt power supply only. Not included.
