Description
The ZVEX Mastotron pushes silicon fuzz design into territory most fuzz pedals never touch. At its core is a push/relax input impedance control that lets you dial the pedal’s front end to match passive pickups or line-level signals, making it a genuinely useful tool for re-amping bass tracks or running keyboards through fuzz after the fact — not just a stompbox for guitar.
- Push/relax input impedance control, adjustable from passive pickup range to line level
- Three-position sub control switch for shaping low-end weight
- Treble tone control for cutting through or darkening the fuzz
- Adjustable pulse width for shifting the character of the gated/square-wave textures
- Wide-range fuzz depth control
On a pedalboard, the Mastotron earns its spot as more than a one-trick fuzz box. Bassists get a dedicated sub switch to keep low end intact even under heavy saturation, while the impedance control means it can sit comfortably wherever your signal chain needs it — front end, effects loop, or as a studio re-amping tool. Guitarists benefit from the same flexibility, with tone and pulse width controls opening up everything from thick, woolly fuzz to more clipped, pulse-modulated textures.
Measuring 4.70″ x 2.38″ x 1.82″, it’s compact enough to fit into busy board layouts without sacrificing the control set that makes it stand out among silicon fuzz circuits.
