The Spiral Electric FX Demhe Fuzz is an analog fuzz pedal built around silicon transistors. according to RockBoard's PedalPedia's PedalPedia listing, it produces chunky lows and scintillating highs that can be tamed by the Detail Control, with tones that range from overdrive to fuzz1. Delicious Audio's Paolo De Gregorio described it at launch as a streamlined version of its big sibling, the Demhe Shadow, itself a custom revision of the company's Black Rose Fuzz, and noted it is related to the Carcosa Fuzz in its Demhe mode2.
Controls
| Control | What it does |
|---|---|
| Gain and Bias | Work together to create tones that can range from seductive purring overdrive to savage roaring fuzz1 |
| Detail | Tames the high frequencies12 |
| Output | Delivers enough boost to punish any amp channel1 |
| Blower toggle | Selects between BAT46 silicon diodes, or the pure unaltered sound of the Demhe's silicon transistors1 |
The Blower toggle is the pedal's clipping selector. In position 1 you get diode clipping and its softer overtones; in position 2 there is no diode clipping, which delivers the unaltered sound of the unit's silicon transistors, louder and more in-your-face2. JHS Pedals' history of the company describes the same arrangement on the original fuzz: "The original fuzz features a Blower toggle that lets you select between BAT46 silicon diodes or silicon transistors."3
Background and availability
The Demhe Fuzz launched in August 2021 as the first Spiral Electric FX pedal hosted in a compact case, at a "smol" price of $149.952. Delicious Audio reported that Reverb.com and Spiral Electric FX teamed up to offer it, a take on a once lost '70s fuzz circuit, available exclusively on Reverb2.
Spiral Electric FX pedals do not have a battery option, so the Demhe Fuzz needs external power2.
The Demhe runs on silicon transistors, which the maker describes as delivering "the pure unaltered sound of the Demhe's silicon transistors," and it carries a list price of $149.952.

Questions
What does the Blower toggle do on the Demhe Fuzz?
The stock Blower Toggle selects between BAT46 silicon diodes, or the pure unaltered sound of the Demhe's silicon transistors. Delicious Audio describes the two positions as diode clipping with its softer overtones (position 1), or no diode clipping, which delivers the unaltered sound of the unit's silicon transistors and is louder and more in-your-face.
Is the Spiral Electric Demhe Fuzz true bypass?
Yes. Delicious Audio lists the Demhe Fuzz as true bypass in its August 2021 coverage of the pedal's launch.
Can the Demhe Fuzz run on a battery?
No. According to Delicious Audio, Spiral Electric FX pedals do not have a battery option, so the Demhe Fuzz needs external power on a pedalboard.
Is the Demhe Fuzz analog?
Yes. RockBoard's PedalPedia listing for the Demhe Fuzz gives its circuit type as analog, built around silicon transistors.
Where is the Demhe Fuzz sold?
Delicious Audio reports that Reverb.com and Spiral Electric FX teamed up to offer the pedal, a take on a once lost '70s fuzz circuit, and that it is available exclusively on Reverb.
