Tweak Fuzz
The tone will be familiar to
those who remember the
lush, soft-clipping fuzz tones
of the ‘60s pop festivals.
I’ve been a working musician and guitar electronics designer since I was a
teenager. I know what sounds right on stage and in the studio; and I know
what will hold up on the road. That’s why all my stompboxes use high-quality
electronic components, low-noise circuitry, heavy-duty sheet metal chassis,
and durable footswitches. That’s why my tube distortion pedals run on high
plate voltage and use mil-spec New Old Stock (NOS) tubes. And that’s why
every pedal we make has true bypass.

But with the addition of the
Tweak switch, you can tailor
your bass reponse to add
incredible thickness, rich
harmonics, and limitless
versatility to your electric
guitar and bass tone.
That’s what boutique quality is all about. It’s about design, components, and
construction. And boutique quality is built into every one of our stompboxes.
