GUP Tech The Rewolwer - Douche Edition

The Rewolwer Douche Edition is a boost pedal from GUP Tech, a small-footprint unit the maker describes as a multi-function JFET driver. Inside are two JFET boosters wired in cascade, followed by a master volume, and the maker positions it as either a boost or an overdrive depending on where it sits in the chain¹.

What it does

GUP Tech describes the layout plainly: "You got two Boosters in cascade (POW, POW) controlled by a Master Volume (BANG)." The two boost stages stack into each other, so pushing them gives what the maker calls "a sweet saturation from the transistors, and the Master Volume makes the amp break up"¹.

The maker suggests three ways to use it: as a boost or as an overdrive at the beginning of an effect chain, or as a clean boost at the end¹. That flexibility is the point of the cascade design: with the boosters low it stays clean, and with them up the JFET stages saturate.

The Douche Edition

The Douche Edition is a sparkling limited edition box of The Rewolwer, announced in October 2025¹. GUP Tech has used the Douche treatment across its range, including the Donut Douche Edition, which pairs the same idea of a sparkling enclosure with a boost-overdrive circuit. The pedal itself is a powder coated die cast aluminum enclosure with a small footprint¹.

Power and practicalities

The Rewolwer is DC negative center compatible with a standard 9V adaptor, the common arrangement for pedalboard supplies¹. Power consumption is listed at 2mA¹, low enough that it poses no strain on any supply output or on a daisy chain.
