JAM Pedals releases Tiny Amp Destroyer with Stu Mackenzie

The JAM Pedals Tiny Amp Destroyer is listed on the maker's site, which describes it as "our original three-footswitch gain machine, combining two independent drive stages with a standalone treble booster"¹². The maker says the circuit began with Mackenzie pushing two Boomsters into a pawn-shop amp, and that JAM "did not simply clone that setup" but used the resulting behavior as the basis for a new design¹².

The two drive stages are labeled G1 and G2. Per the maker, G2 is "the more restrained stage, covering lower-gain breakup and driven tones," while G1 "runs hotter, moving into heavier overdrive and distortion"¹². Both share a Level control and active Bass and Treble controls with boost and cut¹². A MAGIC control shifts the response toward "the compressed, boxy and unstable character of a tiny amplifier being pushed beyond its limits," and Notch "progressively removes a key frequency band as you turn it up"¹². The third footswitch runs an independent treble booster based on the maker's Rooster, placed before G1 and G2 in the signal path¹². An internal DIP switch selects between Full and Standard booster voicings, and the pedal ships in Full mode¹². A G1 Global Bypass mode, selected by holding G1 while connecting power, lets the G1 footswitch control the whole pedal¹².

The artwork was created by Jason Galea, described by the maker as King Gizzard's longtime visual collaborator¹². JAM states that "every limited artwork pedal is a one-of-a-kind hand-painted piece"¹².

The maker's site lists the pedal and a B-stock version without a US price¹². On the September 25 episode of That Pedal Show, host Dan described it as a collaboration with Mackenzie and said the MAGIC button "shifts the overall voicing closer to the response of the small amp"³.
