If you've ever wanted the flexability of adding acoustic tones to your guitar, the Graph Tech Ghost system is the way to go.  Retrofit the Acousti-Phonic to your guitar and enjoy acoustic guitar tones.  You can use your magnetic pickups or both at the same time.  The jack auto-senses whether you're running your rig in stereo or mono and adjusts accordingly: when you're in mono, the Acousti-Phonic Kit sums the piezo and magnetic signals to mono; in stereo, the piezo and magnetic signal come out on different channels.All you need to do is add the appropriate style Graph Tech saddles to your guitar to complete the Acousti-Phonic Kit.The PK-0680-00 is the complete Ghost system for guitar.  It included the Advanced Acousti-Phonic preamp (PK-0240-00) as well as the Advanced Hexpander Preamp (PK-0440-00) with all the optional volume pots and switches.The Complete Kit for Guitar combines the Acousti-Phonic Kit EQ'd for Guitar with the Hexpander MIDI interface Kit, and includes:PD-0240-00 Acousti-Phonic Intelligent pre-amp EQ'd for guitarPD-0103-01 Switchcraft Stereo Switched Output JackPE-5003-00 Stereo Output Jack Cable AssemblyPE-5002-00 Acoustic Volume Cable AssemblyPE-0204-00 Battery Connecter (connects 9v to pre-amp)PE-0205-00 Battery Holder (metal clip that holds 9V battery)PE-0111-00 QuickSwitch for mag/both/acousticPE-0206-00 Acoustic Volume Pot with Mid/Dark SwitchPE-5017-00 Summing Board (not pictured)PE-5021-00 Dual Connector Cable (not pictured)PD-0440-00 Hexpander MIDI interfacePD-0540-00 13-pin Output JackPD-0515-00 13-pin Mounting PlatePD-0512-00 Interface Wiring HarnessPE-0111-00 QuickSwitch for MIDI/both/guitarPE-0180-00 Program Up/Down switchPE-0181-00 Hexpander MIDI Volume PotPD-0511-00 Extension Wiring Harness Features
