Dunable Guitars Dunable SplatterBlaster

The Dunable SplatterBlaster is a fuzz pedal that puts two vintage fuzz circuits in one enclosure: the Splatter side is a Univox Super-Fuzz clone, and the Blaster side is a modified op amp Big Muff¹. It is the debut pedal from Dunable Guitars, and Pedal of the Day describes it as a pedal developed by Dunable Guitars together with Damnation Audio². What makes it unusual is that the two circuits run in parallel rather than in series, with a mix knob to blend them, a clean blend, and stereo outputs that can send each fuzz to its own amp¹.

Two fuzz circuits in parallel

Most two-dirt pedals stack their channels, so one drives the other. The SplatterBlaster does the opposite: its circuits are arrayed in parallel, not series, so Splatter never cascades into Blaster or vice versa¹. That changes what the pedal is for. Instead of adding gain stages for a heavier sound, you are blending two different fuzz voices, in any ratio, or blending either one against your clean signal.

The two voices come from well-known places. Splatter is a Univox Super-Fuzz clone, the octave-up Japanese fuzz design, while Blaster is a modified op amp Big Muff, the version of the Big Muff built around an op amp rather than discrete transistors¹. Pedal of the Day describes the two channels as one fuzzy and one distorted, with the Blaster side covering a range from shoegaze to death metal to Pink Floyd².

A stereo switch routes each effect to its own output, for feeding two amps or a stereo-compatible amp¹. Pedal of the Day frames this as the pedal's reason for existing: it finally lets you run two different channels of dirt to two different outputs².

The controls

Each side has its own control set, and Dunable supplemented the original circuits with extra knobs and switches¹.

The Splatter side's marquee feature is its two-position tone toggle: one setting is fat and scooped, the other snotty and mids-forward¹. Dunable also supplements the original gain and volume controls with a boost pot¹.

On the Blaster side, Dunable added a bass pot that applies a hefty low-end boost centered around 100 Hz¹. The tone control is a faithful rendition of the Big Muff's iconic single-knob design, where the knob's sweep does not simply cut highs but adjusts bass and treble while reconfiguring the midrange¹.

Two features work across both sides. A mix knob blends the fuzzes in varying ratios, and it stays active even when one fuzz is bypassed, so you can mix either fuzz with the clean signal¹. And a phase-reverse switch flips the polarity of one circuit, which matters when you are running two amps or blending signals that can cancel each other's low end¹.

What reviewers said

Premier Guitar reviewed the pedal in September 2023 and summed it up in three lines¹:

The reviewer found the pedal equally potent on guitar and bass, and said its mixing, stereo and clean-blend abilities unlock a world of compelling crunch tones¹. On bass specifically, the verdict was stronger still: "SplatterBlaster may be my fave bass fuzz ever," with devastating results on bass¹. Build quality and value also drew praise: the pedal is well made, with enclosure-mounted jacks and classy metal knobs, and fairly priced at $299¹.

The review was not all positive. The circuits are not very responsive to guitar dynamics, so you cannot clean them up or soften their edges by lowering the guitar's volume¹. The Splatter circuit is not loud: even maxed out, the signal is not much louder than bypass, and its control effects are less pronounced than a Super-Fuzz's¹. On guitar, the Blaster side's bass pot can overwhelm the traditional tone control, generating overly dense and thudding tones¹.

Pedal of the Day reviewed the pedal in October 2020 and called it "truly unlike any other pedal we've seen in our 7 years"².

Power and practical notes

For a player comparing dirt pedals, the parallel layout is the main thing to weigh. If you want a fuzz that stacks gain into a distortion for a heavier composite sound, this is not that pedal. If you want two distinct fuzz voices you can blend with each other or against your clean signal, and the option to run each into its own amp, the SplatterBlaster is built exactly around that idea¹. Bass players get an extra reason to look: the Blaster side's 100 Hz bass boost and the reviewer's bass verdict both point that way¹.
