PION
Fuzz + OD + Boost

The PION is the ultimate three-stage gain pedal: a Fuzz Face-style fuzz with NOS BC183 transistors, a King of Tone-style overdrive with the JRC4580DD op amp and NOS 1N34A germanium diodes, and an Analogman Bad Bob-inspired boost with NOS J201 JFETs. Everything from subtle enhancement to thick saturation in a single enclosure.

PION Fuzz + Overdrive + Boost circuit diagram and control guide

Fuzz Stage

The fuzz side is a modified Fuzz Face circuit built with NOS BC183 transistors, the "softest" sounding silicon that bridges germanium warmth with silicon reliability. It delivers classic, touch-sensitive fuzz that cleans up naturally when you roll back your guitar's volume.


Overdrive Stage

The overdrive is powered by a JRC4580DD op amp, the low-noise version of the same chip found in the King of Tone. It features NOS 1N34A germanium diodes alongside the original silicon diodes, increasing headroom and softening the clipping edge. It provides smooth breakup, warm harmonics, and the dynamics to work as an always-on foundation or a richer drive when pushed.

Boost Stage

The boost is a cascode circuit built with NOS J201 JFETs. Unlike clean boosts, it's a dirty boost that clips early, delivering tube-like breakup, body, punch, and presence with touch-sensitive response. It has enough output to hit your amp harder or bring stacked tones forward in a mix.

Combined Performance

Used individually or stacked, the PION is built for real-world flexibility. Set the overdrive as your core sound, add the boost for leads, or bring in the fuzz for bigger sustain and texture. It is designed to be the only gain pedal you need on a board, in a compact format.

NOS Texas Instruments BC183

NOS BC183 Transistors

A "holy grail" silicon transistor that bridges the gap between germanium warmth and silicon stability. The same type found in the legendary Fuzz Face circuit.

NOS ITT 1N34A Germanium Diodes

NOS 1N34A Germanium Diodes

A highly sought-after germanium diode, famously used in the original Klon Centaur. These increasingly scarce diodes deliver warm, musical overdrive with rich harmonics.

JRC4580DD Low Noise Operational Amplifier

JRC4580DD Op Amp

The low-noise variant famously used in the King of Tone. Delivers warm mids and smooth clipping that defines the Bluesbreaker lineage.

NOS J201 JFET

NOS J201 JFETs

One of the most sought-after JFETs in boutique pedal building, prized for its tube-like warmth. Hand-tested from an increasingly scarce supply.
