Input gain
This switch lets you quickly set the best operating level for your pickup. Start with
the input gain switch set to normal. When you play hard, the clip/batt LED
should fl ash only occasionally. If the LED does not fl ash with hard playing, select
boost. Typically, soundhole pickups will
require a gain boost while onboard pre-
amp systems will use the normal setting.
The pedal is designed to automatically
maintain constant level when switching
between normal and boost positions,
so you will hear no difference in the over-
all output level when setting this control.
