A sub-heavy silicon fuzz with some new twists: An input impedance
control (push/relax) that adjusts from passive pickupsto line level. It
works very well for re-amping bass tracks that needto 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.
Pedal Dimensions (LxWxH): 4.70" x 2.38" x 1.82"
OVERVIEW:The Mastotron™ is a new, heavy silicon fuzz 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 inter-
faced with digital devices like recorders as well as key-
boards. Let’s go over the complete set of controls:
RELAX/PUSH: This knob
introduces source imped-
ance 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
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
Plug your guitar (or any effect’s output) into the right hand
input jack. Plug the output into an amp or other effect’s
input. 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 (I like it all the way up), 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.
I recommend that you try the Mastotron™ first in your pedal
chain, just after the guitar. 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
