Wampler Mofetta Overdrive/Distortion Quick Reference Manual page 3

Power: This pedal was designed around
the usage of a 9V DC power source.
To avoid damage to the pedal, do not
exceed 9V DC, do not use center pin
positive adapters, and do not use AC
power. Use only a 9V DC power source
that is intended for guitar pedals. This
pedal draws approximately 10mA at 9V.
Please note this pedal may ship with a
battery. If you are powering with a power
supply we recommend removing the
battery by taking the backplate off.
Tips 'n' Tricks:
• As you turn the gain up you might want
to turn the bass down to avoid a "woofy"
tone. As you turn the gain down, turn the
bass up or else it might sound a bit thin.
• The texture switch changes gain
structure entirely - the diode clipping
circuit (switch down) utilizes MOSFET-
based op-amp and diode clipping, the
alternate position (switch up) utilizes
cascaded MOSFET gain stages, sort of
analogous to multiple 12ax7 tube stages
combined with diode clipping.
• Lower gain settings/diode clipping
mode engages a bit more treble to
provide nice, crispy tones. You may
want to dial the treble down to prevent
excess "sizzle" when used in higher gain
settings.
