"I can not live without my Ghost Acoustic MIDI System, All of my Recordings and Touring Depend on The Ghost system. The tracking is unbelievable, and I love that I can change the piezo saddles as easy as a guitar strings. My new album "Global Kiss" Has a #1 single on Billboard Radio charts "Fun in the Sun" using the Ghost system."
- Steve Oliver, Artist, #1 single "Fun in the Sun" Billboard Radio Chart
The ghost Acoustic/MIDI system adds MIDI interface capability and a studio quality acoustic preamp to most nylon or steel string acoustic guitars. The same set of pickup saddles drives both the MIDI and acoustic modules at the same time!

All The Benefits of String Savers
Custom-engineered piezo crystals are encapsulated in a set of Graph Tech’s patented String saver saddles that dramatically reduce string breakage while resonating in the frequency range needed to achieve true, full-bodied acoustic tone that is not possible with a metal saddle.
Individually calibrated for even string-to-string output, these permanently-lubricated, precision balanced saddles have a natural compression effect, so you can play as hard as you want, without overloading the input channel and experiencing the dreaded
Plug-In Without Sounding Plugged-In
The ghost Acoustic MIDI system comprises two electronic modules that install inside your guitar: the Hexpander MIDI Interface, and the Tone Control acoustic preamp with 3-band EQ (and a mid-sweep control, for optimal shaping of your sound). This lets you plug in and amplify your acoustic guitar with remarkably faithful tonal quality by operating with the latest MIDI converters like Roland GR33, GI-20, VG99, Axon AX-50, AX-100, and many more while using your guitar as a controller for MIDI or Virtual sounds.
A Whole New World of Sounds
MIDI/Virtual sounds can be authentic acoustic guitar samples, or exotic patches like horns, strings, percussion, bass, electric guitar and amp combinations, or synthesizer sounds from the realm of keyboard instruments. Now all this is possible right from your acoustic guitar as the musical source.
Dreams of MIDI guitar have long been hindered by poor tracking, but now Graph Tech’s ghost pickup saddles and Hexpander MIDI Interface Module provide incredibly fast and accurate tracking, so you can even play both acoustic and MIDI/Virtual sounds simultaneously for a limitless palette of blended sounds.
Choose a ghost Acoustic/MIDI Kit for either Steel or Nylon stringed guitars. Installation for flat or radiused fingerboards is possible by omitting or including the provided pagoda shim. Saddles fit a 1/8” saddle slot. Some modification of the instrument is required to install pickups and output jacks.
