Volume Control

This is a master volume control for both the pickup and the microphone. Set this as
high as possible (without distorting your amp or mixer) for the cleanest signal.
Notch and Phase
These controls work hand in hand to suppress two adjacent ranges of acoustic
feedback. When you set them properly, you can play your instrument as loud as
you like, feedback free.
Notch
Tune the Notch filter to scoop out the lowest range of feedback when you play
bass notes between the open low E string and (up to and including) the forth fret
G sharp on the same string. Low frequency "cavity resonance" feedback can
usually be squelched by setting the Notch control between one o'clock and two
o'clock on the dial. Note that for instruments that do not suffer from low fre-
quency feedback, the notch can be defeated by moving the dial to the Off
(seven o'clock) position.

Phase Switch

Flip the Phase switch back and forth until you find the position that sounds best
and subdues mid-bass feedback. Mid-bass feedback generally occurs when you
play bass notes above the fourth fret G sharp on the low E string.
Bass
This control affects the under-saddle pickup signal only! A Boost here will add
depth and weight to the sound the instrument.
