Zvex Vextron Mastotron

A sub-heavy silicon fuzz with some new twists: An input impedance control (push/relax) that adjusts from passive pickups to line level. It works very well for re-amping bass tracks that need to be fuzzed up after tracking and keyboards. There’s also a three-position sub control switch, a treble tone control, adjustable pulse width, and a wide fuzz depth control. More flexible than any silicon fuzz to date.

CONTROLS

RELAX/PUSH: This knob introduces source impedance to the signal going into the Mastotron. When fully up, the signal goes in raw... when turned down, source impedance is added as needed to “soften” the input for active pickups.

FUZZ: This wide-range knob lets you set just how fuzzy your Mastotron gets.

PW: Pulse Width control. You can swing this from square wave on the left to narrow pulses on the right.

TONE: This shapes the treble without sacrificing the heavy subs.

VOL: Output volume. SUBS Switch: “2-1-3” Lets you set how much sub content is in your fuzz. It’s pretty dramatic... 3 is huge, 2 is medium, and 1 is absolutely none left. Totally twinky. Try 1 with the tone turned down!
