The Stomp Under Foot Dirt Preacher is an analog fuzz pedal built around a hybrid of silicon and germanium transistors. RockBoard's PedalPedia describes it as giving "a full range of fuzz tones that sounds like a mix between a Big Muff™ and a Tone Bender™ through your favorite, vintage amp"1. For players, that places it in the territory covered by both the muff-style fuzzes and the Tone Bender-style fuzzes, two of the classic fuzz families.
What it does
The hybrid transistor design is the heart of the pedal. according to RockBoard's PedalPedia, "the specifically matched, germanium transistor gives you a vintage grittiness and a little, tube-like sag"1, while the silicon side carries the louder, more compressed part of the fuzz character. The gain control sweeps across the pedal's whole range rather than acting as one fixed voicing.
| Gain setting | What you get |
|---|---|
| Around 9 to 10 o'clock | An overdriven tone1 |
| Between 11 and 1 o'clock | A smooth, muff-like fuzz1 |
That sweep means the Dirt Preacher can sit on a board as a low-gain dirt pedal and still deliver full fuzz when pushed, which is unusual for a single-knob-range fuzz. Players who want a dedicated take on either side of its character can look at Stomp Under Foot's other fuzzes, such as the Green Russian or Ram's Head on the muff side, or browse the wider field on the Fuzz Pedals page1.
Power and practicalities
The Dirt Preacher runs on 9V DC, center negative, and draws 8mA1. That current draw is low enough for any standard isolated supply output, and it will not strain a daisy chain the way higher-draw digital pedals can.
The pedal is analog, so it behaves like other vintage-style transistor fuzzes on a board: where the fuzz sits in the signal chain, and what feeds it, shapes how it responds.

Questions
What kind of pedal is the Dirt Preacher?
It is an analog fuzz pedal from Stomp Under Foot built around a hybrid of silicon and germanium transistors. The maker describes its range as a mix between a Big Muff and a Tone Bender played through a vintage amp, and it can also produce overdrive-style tones when the gain is kept low.
How is the Dirt Preacher powered?
It runs on 9V DC with a center negative plug and draws 8mA, which is light enough for most standard pedalboard power supplies.
