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!
