The ghost® system is designed to t most
guitars and basses. Installing it requires
replacing the saddles on your bridge with
compatible ghost® pickup saddles. Graph Tech
makes these for Strat and Tele style guitars,
guitars with Tune-O-matic style bridges like
Gibson and Epiphone, Wilkinson, PRS, P-bass,
Jazz bass, and any
bass that can accept
a Hipshot A-style
bridge or ABM
saddles. Floyd Rose
Original and Licensed
bridges can be replaced with our pickup-loaded
ghost® LB63 bridge. Some installations can be
done without altering the instrument at all,
while others will require drilling, notching, or
routing. This depends on the components
you choose, and the design of your
particular instrument.
Will it work with my guitar?

Modular means that the ghost® system’s components can be
plugged into each other in dierent combinations to create
dierent systems. Once you’ve selected pickup saddles to t
your guitar, these can be connected to the Acousti-Phonic™
for authentic acoustic sound from your electric guitar,
or to the Hexpander™ to interface with MIDI and virtual
instruments. Or both the Acousti-Phonic and Hexpander can
be “piggybacked” together. You can add as many or as few of
the optional controls as your instrument will accommodate.

Output options
Replacing the 1/4” output jack with the Stereo Switched Jack
supplied with the Acousti-Phonic permits the output of two
signals, magnetic and acoustic, through one jack. The 13-
pin jack installed with the Hexpander carries the hexaphonic
signals for MIDI conversion, and can also carry the magnetic
and acoustic signals so that a 1/4” patch cord is unnecessary.

Mono and Stereo Modes
The Acousti-Phonic detects whether you’ve inserted a
stereo or mono plug into the 1/4” jack and automatically
switches to Stereo (separate) or Mono (blended) mode.
In Mono mode, the acoustic and magnetic signals are
blended together in the Acousti-Phonic and delivered
together on the Tip contact. You can plug into one guitar
amp and switch between sounds, or enhance your unaltered
magnetic tone by dialing in a little of the acoustic sound.

In Stereo mode, the acoustic signal is on the Ring contact, and the
magnetic signal appears on theTip contact so that you can process
these signals separately using a stereo-to-two-mono Y-cable.
For example, run your magnetic pickups through a crunchy
guitar amp and your acoustic sound through a clean P.A. system.
