ZVex Mastotron Fuzz

I was looking to do a write up on a bass pedal this afternoon, and stumble on something that bass players and guitarists might find very cool. This is the ZVex Mastotron Fuzz pedal. I saw some mention that the Mastotron Fuzz was being used by a few bass players, so I wanted to take a look, oddly all the clips were with guitars, and I was impressed. If you’re looking for a HEAVY fuzz tone, this could be the box you need. I was impressed with the solid low end and options for dialing in that fuzz. Good to get some wool in there.. or to go total stoner heavy. I’m liking it!

I’m definitely liking the ZVex stuff (recently did a post on the ZVex Fuzz Factory), so it was nice to look at another pedal in their line.

Here is the official description:

The Zvex Vextron Mastotron Effect Pedal is a new, heavy silicon fuzz effect pedal design that includes a couple of unusual features- source impedance control, subs control, and pulse width control. It works equally well with bass and guitar, and can easily be interfaced with digital devices like recorders as well as keyboards. The controls: * Relax/Push: This knob introduces source inpedance to the signal going into the Mastotron. When fully up, the signal goes in raw…when turned down, source inpedance 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.

I found two videos related to this. I thought they both showed what it can do in different ways. Also, showing some of the limitations, etc.
