Keeley Psi Fuzz Effect Pedal
A classic op-amp fuzz sound with a few Keeley tweaks! Keeley took the op-amp version of old Big Muff deisgn and inverted one of the stages, brought out the midrange, tightened the bass, and most importantly, added a Germanium transistor output! Yes, this is a opamp-transistor hybrid. Don’t be miffed by op-amps in your pie folks, the germanium touch at the end makes everyone smile around the Keeley shop, and at The Music Zoo too!
