VOLUME: Adjusts the overall output level of the preamp.
BASS: Adds or subtracts the low fre quen cy content of the signal.
MID: Controls the amount of a broad range of frequencies in
the middle of the sound spectrum of the guitar.
MID1: Controls the amount of power in lower middle fre quen cies.
MID2: Controls the amount of power in upper middle fre quen cies
TREBLE: Adds or subtracts the high fre quen cy content of the signal.
EQ IN/OUT: Engages or bypasses the EQ controls.
PRESHAPE: Engages or bypasses a fi xed tone en hance ment circuit.
MID SHIFT: Moves the center frequency of the midrange control.
NOTCH SW: Enables or disables the Notch Filter (see
).
NOTCH POT: This control is used to tune a very sharp and deep fi lter
designed to reduce feedback when using high-gain
amplifi cation. At a high volume level, your guitar may
“feedback” causing a low, steady tone to come from your
speak ers. With the notch fi lter enabled, slowly tune this
control to the feedback frequency (CW=higher frequency,
CCW=lower fre quen cy) until the feedback is re duced.
TUNE/CAL: This switch turns on the built-in tuner for approximately 60
seconds. Press a second time while playing a note and this
pitch will become the cal i bra tion point for operation
(handy when tuning to an “out-of tune” in stru ment). During
the tuning op er a tion the guitar output will be muted. If you
fi nish tuning prior to the 60 second timer returning the tuner
to idle (and un-mute), you may press this button again to
manually return the preamp to normal operation.
TUNER LEDs: These LEDs indicate the note being played and whether it’s
sharp or fl at. Tune string up or down until the LED lights.
BAT: When steadily illuminated, indicates that the battery is low
and should be changed soon. Also intermittently fl ashes
when plug is in sert ed into jack to confi rm normal op er a tion.
RELEASE: Pressing this button will release the module from its recep-
tacle. Use this button to access to the battery com part ment.
MODULE: The preamp is housed within this module and mates to the
receptacle mounted in the body. Remove this module to gain
access to the battery compartment. See the il lustra tion on the
last page for instructions on replacing the bat tery.
