The short version

A small, nasty amp with a very big afterlife

The JAM Pedals Tiny Amp Destroyer is a limited-edition collaboration with Stu Mackenzie of King Gizzard & the Lizard Wizard. Its starting point is not a famous studio amp or a museum-grade circuit. It is a tiny Cash Converters find that Stu loved precisely because it sounded cheap, stressed and ready to fall apart.

On recent King Gizzard records, Stu had been running two JAM Boomster clean boosts into that little amp until it stopped behaving like a polite amplifier. JAM tracked down the same model, recreated the setup and concentrated on the moment where the response shifts from ordinary breakup into something more unstable, compressed and alive.

“Shitty is pretty!”

What is inside

Three switches, from pushed drive to full destruction

This is not a one-sound novelty pedal. JAM split the gain into two stages, then placed an independent treble booster in front so the core character can be built and reshaped in several ways.

G1 and G2 share Level, Bass and Treble controls, so there is enough active EQ range to pull the pedal out of its deliberately boxed-in origins when a fuller, mix-ready drive is the better choice. The treble booster has its own level control and an internal switch for full or more traditional voicing; the pedal ships in the fuller setting.

Built through use

From Athens prototype to finished pedal

JAM took a prototype to Stu during King Gizzard's Athens residency. After a minute of playing, his verdict was simple: “you nailed it.”

More importantly, the prototype did not stay in a demo room. Stu used it for the rest of the tour, and that real-world run helped settle the pedal's final shape. It is a fitting development story for a circuit designed around an amp that had already travelled the world with him.

Jason Galea artwork

The enclosure artwork comes from Jason Galea, the visual force behind much of King Gizzard's world. Its trapped, straining figures mirror the circuit's central idea: something held in place and forcing its way out.

Who it is for

A character drive first - but not only

Tiny Amp Destroyer makes the most sense for players who want their drive sound to have a point of view. Still, its range is broader than the blown-speaker aesthetic might suggest.

• Run G2 alone for lower-gain breakup and an everyday drive sound.
• Use G1 as the main distortion when you want more urgency and saturation.
• Stack G1 and G2 when the song needs the pedal to start coming apart.
• Use the treble booster alone, or push it into either gain stage for extra focus.
• Engage Magic and shape Notch for the most pronounced small-amp character.
• Pair it with a clean or dirty amp and expect the rig to react differently each time.
