Pigtronix OFM
Pigtronix · pedal
The Pigtronix OFM Disnortion Micro combines a 6-stage CMOS overdrive circuit cascaded into Pigtronix's diode-clipping fuzz circuit, with output shaped through a 6-way passive filter network, all in an enclosure under 4 inches tall and 1.5 inches wide. A single Gain knob controls saturation for both the overdrive and fuzz circuits simultaneously, a switch selects parallel or series routing between the two gain stages, and a rotary Drive Tone filter switch provides 6 distinct EQ curves. It runs on 9V power with 18V internal headroom for a dynamic, tube-like overdrive response layered with controllable, feedback-capable fuzz.

“with output shaped through a 6-way passive filter network”
— from the listing
“Valued for packing two distinct gain circuits, a dynamic CMOS overdrive and a diode-clipping fuzz, into one compact pedal with genuinely useful routing flexibility between them”
— from the community notes
“18V internal headroom despite 9V external power is a thoughtful design choice, giving more dynamic range than a straightforward 9V-only circuit”
— from the reviews
Trade-offs
“6-stage CMOS overdrive circuit is specifically designed to respond to playing dynamics, retaining natural tone at lower intensity while adding tube-style breakup as players dig in harder”
