You will also need to order ghost Saddle Pickups or a ghost-loaded Bridge Assembly to complete your ghost system. Pickups are different for every type of guitar bridge, so they are always ordered separately from the kits.

To use the Acousti-Phonic in Stereo Mode (two amps, mag and acoustic) you'll need a Stereo Y-Cable.

The Installation manual is available Here 

Acousti-Phonic Modular Pre-amp 

  • for studio-quality acoustic sound from your electric guitar or bass. 
  • captures the natural acoustics of your electric guitar -- hear the sound of the wood!
  • can be amplified or recorded directly
  • eliminates feedback or mic placement problems associated with an amplified acoustic guitar
  • automatically detects and selects mono (single amp) or stereo (dual amp) operation
  • onboard ghost pickup volume control to adjust the magnetic/acoustic mix
  • auxiliary 9v - 18v power for active mag pickups  -- eliminates the need for two sets of batteries
  • included jack shuts off all on-board devices when 1/4" cable is unplugged
Hexpander MIDI Interface
  • adds MIDI capability to almost any guitar or bass. Interface your guitar with pitch-to-MIDI converters by Roland and Axon. 
  • Fast, accurate tracking.
  • Low-latency design perfectly complements today’s state of the art pitch-to-MIDI converters.
  • Operates with the latest MIDI converters and Virtual Guitar systems: Roland GR55, VG99, StringPort, as well as legacy units like Roland GR33, GI-20, and V Bass,  Axon AX-50, AX-100, Yamaha G50, and many more.
  • Add the ghost® Acousti-Phonic pre-amp and/or optional switches at any time by simply plugging them in…no rewiring or soldering.
  • Optional plug-in MIDI Volume, Momentary Up/Down Program Selector Switch (S1/S2) and QuickSwitch (MIDI/both/mag+acoustic) for an infinite palette of tonal possibilities.
  • Optional pin-7 wiring harness available for accessing a summed piezo signal.
  • The Acousti-Phonic Pre-amp and Hexpander MIDI Interface can both be used as stand-alone systems, or can "piggy-back" on each other for a complete set of features. Optional Plug-in-Switches allow you to flip between magnetic, acoustic or hex outputs, or blend the three for an infinite palette of tonal possibilities.
