This is the complete Graph Tech Ghost system EQ'd for bass. It included the advanced Acousti-Phonic preamp as well as the advanced Hexpander Preamp along with all the optional volume pots and switches and all parts required to install the it (your bass will need Graph Tech Ghost saddle pickups to work with this system).

The Ghost system allows you to add realistic acoustic tone on board without having to switch basses, the kit includes optional upgrade components to get the maximum flexibility from the ghost piezo system. The kit includes the Ghost Quickswitch which allows you to switch between magnetic pickups, piezo pickups or both, and also the Ghost Mid/Dark Volume pot which allows you to control the volume of the Acoustic-Phonic output and also incorporates a push/pull switch which selects between two EQ curves for the output, the normal ghost sound and one with a boost in the mid range (around 2 kHz).

The Hexpander MIDI system allows you to add a whole orchestra of sounds at your fingertips. Having other instrument sounds while still playing guitar is an excellent option if you want to broaden your compositions or live sound without having to switch or learn to play new instrument. The Graph Tech Ghost Hexpander is the fastest MIDI tracker available and you can set it up in a variety of different ways including different strings for different instruments, or low frets and high frets as different instruments. You can also feed the magnetic signal down the 13 pin midi cable and then run a standard 1/4" cable from your MIDI converter to your guitar amp, meaning you only need one cable coming out of your guitar (requires Hexpander mag to pin 7 harness available separately from Graph Tech, NOT included). The Traktion switch built in to the 13 pin jack plate selects between Roland and Axon for best tracking results (if you are using a different brand converter switch between the two to find the best result). The kit includes the Hexpander MIDI volume pot, momentary up/down switch which scrolls up and down through your MIDI converter's sounds (called a S1/S2 switch on some converters) and the Ghost Quickswitch which allows you to switch between guitar pickups, MIDI or both (the output from the Acousti-Phonic Quickswitch will go to the MIDI Quickswitch, so piezo/magnet/MIDI all together is available).
