The ZVex Vextron Mastotron works equally well with bass and guitar, and can easily be interfaced with digital devices like recorders as well as keyboards. Set the amp for a warm clean tone on bypass. Turn on the pedal and rock out!

Using a guitar or bass, turn the Relax/Push knob down a bit if you need to until the fuzz sounds immediate and tight. Turn the fuzz control until you're happy, and set the PW to square (counter-clockwise). Adjust the tone for the treble amount you want, and use the sub switch on 3 for full heavy subs for bass or 2 if the subs are overloading your amp. Try turning down the Relax/Push knob all the way. Now, turn up the PW knob until it gets all the way to the pulse side. Try turning up the Relax/Push knob now. For a strange effect, set the subs switch to 1 and then turn down the tone control all the way. You’ll have to turn up the volume control with this setting.

You can set the amp for your favorite clean tone for the most blistering results, but a distorted sound can be very cool as well. Play it into your favorite distortion pedals or direct into the amp for different textures. Try putting weird effects into the Mastotron and adjust the Relax/Push knob for best interfacing.

Sounded great, not much gain on tap


It's definitely a great sounding fuzz pedal. Very versatile, nice and warm, in general a big tone range. I was not very pleased with the actual gain it had on tap. I was Kindof hoping it would achieve more. But not to discourage one from buying/trying it themselves.
