Mask Audio Electronics & Holy Island Audio STOP! Dual Fuzz

The STOP! Dual Fuzz is a collaborative release between Mask Audio Electronics and Holy Island Audio, reported by Delicious Audio on 28 July 2023¹. It puts two existing circuits in one enclosure: the Holy Island Audio Abracadaver octave-up fuzz circuit on the left side, and the Mask Audio Electronics Yes fuzz on the right. Delicious Audio describes the result as "a wild and chaotic pairing of speaker shredding noise"¹.

For a player, the appeal is straightforward: instead of buying and ordering two separate fuzz pedals, you get both circuits in one box, each with its own bypass footswitch, and a toggle that reverses which one comes first. The Abracadaver side is an octave-up fuzz with a couple of tricks up its sleeve, per the same write-up¹.

Two fuzzes in one box: octave-up and Yes

The pedal combines the HIA Abracadaver octave-up fuzz circuit and the MAE Yes fuzz in a single enclosure¹. Each circuit can be engaged independently with its own bypass footswitch, so you can run one, the other, or both at once¹.

The Abracadaver itself is described by its maker as a simple way of adding a sprinkle of chaos to your other drive pedals: place it before your fuzz for a fuller, more harmonically rich sound, or place it after fuzz to turn it into a wild octave fuzz in the vein of an Octavia². That flexibility is baked into the STOP!, where the Order toggle decides whether the Abracadaver sits before or after the Yes circuit.

Holy Island Audio is a Cardiff-based maker known for compact pedals including the Spectral Fire Drive, the Micro Mountain Mover Super-Muff, and the Blast Radius oscillating fuzz, the latter built around three independently selectable gain stages³⁴.

The controls

The two sides of the pedal mirror each other, with a volume control and a character control on each, plus toggles that change each circuit's voicing¹.

The Stronk switch is worth a note for players who want more than full-on chaos: in its lower gain position the Abracadaver side can sit near overdrive territory rather than screaming fuzz¹. The Texture toggle on the Yes side is the equivalent shaping tool for that circuit, moving between a big, thick voice and a thin, compressed one¹.

Power: 9V DC only, no battery

The STOP! runs on a 9V "BOSS style" DC adapter only, with no battery option¹. That means a standard center-negative 9V supply, the same format used by most pedalboard power bricks.

One buying note from the release coverage: international orders may be subject to customs fees, and all additional fees are the buyer's responsibility¹.

Built from the Abracadaver and the Yes

The STOP! is not a new circuit design but a pairing of two existing ones. The Abracadaver comes from Holy Island Audio, a maker known for compact pedals including the Spectral Fire Drive, Micro Mountain Mover Super-Muff and Blast Radius Oscillating Fuzz³. On its own the Abracadaver is described as a simple way of adding a sprinkle of chaos to your other drive pedals: place it before your fuzz for a fuller, more harmonically rich sound, or place it after fuzz to turn it into a wild octave fuzz in the vein of an octavia².

The Order toggle idea also has a precedent at Holy Island Audio: the Tides V2 reverb and distortion pedal introduced an Order toggle that switches the routing of its two circuits⁵. On the STOP!, both effects are wired in series, and the order toggle determines which circuit is placed last in the chain; whichever circuit the toggle is flicked towards is last¹.

Every Holy Island Audio pedal is printed and assembled in Cardiff, Wales, where the maker is based¹.
