Here is what Mike says…
One knob Fuzz..
It does what it says on the label.
It's a full-on, unapologetic, growling, snarling.. beautiful FUZZ.
Hand-wired single transistor fuzz circuit built onto a vintage style tagboard strip.
It's beating heart is an MPSA13 transistor and a BAT41 companion diode.
One knob to adjust the volume, an LED status light and true-bypass switching. Powered via 9v centre DC external power only.
What more do ya need?..’
