Heather Brown Electronicals Sensation Fuzzdrive

The Sensation Fuzzdrive is a hand-wired fuzz and overdrive hybrid from Heather Brown Electronicals, the pedal company of builder Heather Brown. Premier Guitar described it as "marketed as a fuzz-meets-overdrive circuit, with the tight punch of an OD and the earth-rumbling thunder of fuzz"¹. Where a straight fuzz pedal gives you one flavor of saturation, the Fuzzdrive lets you dial between the two worlds, from warm overdrive up to heavy fuzz, using a selectable number of transistor gain stages and a set of preset EQ toggles.

Heather Brown built her reputation with the Blessed Mother Overdrive, and the Sensation Fuzzdrive followed it in the lineup²³¹. Delicious Audio called it "a very tweakable blend of fuzz and overdrive that can deliver the best of both worlds"⁴. Pedal of the Day found it "blends punchiness and warmth, without sacrificing body or getting too fizzy"².

A fuzz that blends into overdrive

The core of the pedal is its gain staging. The circuit offers up to three selectable, transistor-based gain stages, and a 3-stop knob switch called the Saturator selects how many of them run in series¹⁴. With fewer stages engaged the pedal behaves more like an overdrive, with the tight punch that implies; stacking all three pushes the signal harder into fuzz territory. Gearnews noted the pedal carries "the usual volume and fuzz controls (saturator)" alongside its toggles⁶.

The circuit is built around a low-input impedance design, and Heather Brown suggests situating the pedal before other effects in the chain, as Premier Guitar's review noted¹. That kind of input behavior is familiar from vintage fuzz designs, where the pedal reacts strongly to what feeds it.

The instructions include six control setting suggestions that range from warm overdrive to heavy fuzz¹, so a player new to the circuit has documented starting points rather than a blank slate.

The controls

Beyond the Saturator, the control set is a mix of one dial and several toggle switches⁵.

The three toggles give the pedal a preset EQ grid rather than continuous tone knobs: three midrange voicings crossed with three bass levels, plus the hi/low gain switch. That is a lot of combinations, and Premier Guitar's reviewer found the trade-off real⁵²⁴:

The same review framed the pedal overall as "a versatile fuzz and distortion"¹, so the EQ quirks sat alongside a broadly positive verdict.

Where it came from

Heather Brown made her name with the Blessed Mother Overdrive, her first release, and the Sensation Fuzzdrive arrived as the next effect in the lineup⁴². Gearnews described the Fuzzdrive's circuit as similar to the company's previous breakthrough, the Blessed Mother⁶. The pedal was unveiled in May 2022 and sold as a limited edition exclusively through Reverb as part of Reverb's Maker's May campaign⁵⁷. Gearnews reported it as a Reverb exclusive at around 270 euros including shipping⁶, while MusicRadar gave the launch price as £211 / $249⁷, and Premier Guitar later listed it at $249¹.

Premier Guitar also singled out the enclosure, calling its artwork "some of the coolest art ever committed to a little steel stompbox"¹.
