657 Mini Mutant Noise Synthesizer Pedal

MicroAnalog

$227

Ever since Trogotronic started crafting these pint-sized analog chaos machines, the 657 Mini Mutant has stood out as the ultimate pocket-sized weapon for jamming up clean signals with unpredictable noise barrages.

This all-analog beast packs a blistering audio output and input for mangling anything you feed it, from guitar riffs to synth lines. Five toggle switches unlock 25 distinct sonic assault modes, while five clearly labeled knobs give you hands-on control over parameters like frequency, resonance, and intensity—discrete transistor circuitry ensures that raw, authentic analog grit. Housed in a rugged cast aluminum chassis measuring just 4.5 x 3.5 x 1 inches, it fits standard pedalboard power and thrives in tough conditions, ready to plug in worldwide with the included supply.

Noise enthusiasts love its intuitive layout for live improvisation, turning pedals into glitchy wastelands or harsh drones—though some note the extreme output demands careful amp pairing to avoid overload. It's a staple in Trogotronic's lineup for anyone chasing unhinged analog mutation without the bulk.
