GAIN sets your pre-gain. There is a mellow crunch, just like chewing on a delicious femur.

Zacky recommends that you balance the setting with your DRIVE and VOLUME (in the Overdrive section) as these act symbiotically. 

BASS and TREBLE give you an amp-like response.

FUZZ affects the amount of Fuzz you can add to your signal.

As always, start with these controls at 12 o’clock and tweak them until you hit the sweet spot. You’ll get the best results with a clean amp channel or a crunch channel set to low gain.

VOL controls the output volume of the pedal. 

BYPASS stomp switch with an LED indicator activates your new Preamp pedal

A hidden internal switch allows you to run your pedal as a preamp. The “up” position is for the preamp volume, so the signal is stronger and brighter to feed your power amp input. The “down” position is for use in front of the amp (we recommend a clean channel).

Use a clean 9V DC center negative power supply adaptor or a good quality battery.
