USER’S GUIDE
This fine instrument is equipped with a FISHMAN PREFIX™
ACOUSTIC GUITAR SYSTEM.
Please read these instructions carefully. If you have any questions or
problems, please call our CUSTOMER SERVICE LINE at (978) 988-
9665.
The PREFIX™ is an instrument-mounted pickup / preamp system that
offers total control of your amplified guitar sound.
THE PICKUP
The PREFIX™ ACOUSTIC GUITAR SYSTEM includes a FISHMAN
ACOUSTIC MATRIX pickup; made with a unique co-polymer sensing
material available exclusively from FISHMAN. This technology is not
available from any other manufacturer. The sensing material exhibits a
sensitivity and dynamic range that far surpasses all other known sens-
ing materials.
The ACOUSTIC MATRIX transducer is a fully EMI shielded, multi-layer
sandwich of co-polymer strips that run the length of the pickup. This
design allows the pickup to sense the motion of the entire saddle
length, providing superb string to string balance, as well as sensitivity
to both the strings and top of the instrument.
THE PREAMP
The PREFIX™ preamp module incorporates a unique "flip-top" battery
compartment for easy access. Level is set by the VOLUME control.
Shelving BASS & TREBLE and a semi-parametric CONTOUR control
are included for precise tone shaping. A LOW BATTERY indicator lets
you know when it’s time to change the battery.

PREAMP FUNCTIONS
BATTERY COMPARTMENT
Pull the small tab at the top of the PREFIX™ preamp toward you.
The body of the preamp will swing out, revealing the BATTERY COM-
PARTMENT. Insert a fresh 9V alkaline battery.
ENDPIN JACK
The PREFIX™ has no ON/OFF switch. It is turned on only when an
instrument cable is plugged into the endpin jack. To conserve the bat-
tery, remove the instrument cable from the endpin jack when the unit
is not being used.
NOTE: Plug an instrument cable into the endpin jack before you plug
into the sound equipment. Doing so will prevent loudspeaker damage.
BATTERY LOW LED
When plugging into the endpin jack, the LOW BATTERY light will flash
momentarily, indicating that the power is on. When the LOW BATTERY
light stays on, it is time to change the battery.

CONTROLS
VOLUME CONTROL
The Volume control affects both microphone and pickup. Goes from
very quiet to very loud.
BASS CONTROL
This is a boost/cut shelving tone control. The center detent yields a
flat response.
CONTOUR This is a wide-range semi-parametric filter. It may be
used to shape the instrument's tone or to control feedback (see
pages 5 and 6).
The CONTOUR Level slider controls the amount of boost or cut
applied to the selected Contour FREQUENCY. The center detent
yields a flat response.
The Contour FREQUENCY slider determines the frequency band
that is boosted or cut by the CONTOUR Level control. The fre-
quency is variable between 250 Hz and 10 kHz.
TREBLE CONTROL
This is a boost/cut shelving tone control. The center detent yields a
flat response.
