Believe it or not, this PCB will let you build a clone of the Fender Blender.
But not the beloved 4 knob octave fuzz but a odd and rare 3 knob fuzz under the same name that shares no similarities with the 4 knob version and doesn‘t even have a blend control.
Next to the usual Sustain (Gain) and Volume knobs you have a rotary switch that switches between 3 different Fuzz settings and a pretty good sounding Boost/Preamp.
So go ahead and build something unusual.
