JAM Pedals Tiny Amp Destroyer
Stu Mackenzie's favourite $30 pawn-shop amp - crunchy, boxy, buzzy and pushed far past good taste - has been rebuilt as a signature drive pedal.
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.
$30
The unlikely reference
A pawn-shop practice amp chosen for its boxy, buzzy character rather than its pedigree.
2 + 1
The gain architecture
Two independent gain stages plus a separate treble booster at the front of the circuit.

The prototype verdict
Stu played it in Athens, said JAM had nailed it, then used the prototype for the rest of the tour.
“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.
Signal path at a glance
First
Treble booster
Rooster-derived boost that can tighten the lows, sharpen the attack or work alone.
Gain stage
G1
The hotter side, moving from driven tones into more forceful distortion.
Gain stage
G2
The more restrained side, covering lower-gain breakup and a gentler push.
Together
G1 + G2
Stack both stages for the dense, saturated end of the pedal's range.
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.
Magic
Engage the Magic toggle to shift the overall response closer to the small-amp inspiration. It is the direct route to the pedal's most distinctively boxy behaviour.
Notch
Turn Notch up to progressively remove a key frequency band, moving from a full, forward voice toward something scooped, hollow and more extreme.
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.
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.
