Roland GS500 guitar controller/synthesiser modified with an active EMG pickup and equipped with a Roland GK-2A MIDI pickup. The original pickup and synthesiser system designed to work with the GR500 controller are long gone. The pickup ring is broken but still holds. Both original cavity plates are gone, replaced by generic black plates.
 
Both the regular output from the EMG and the MIDI output from the GK-2A work fine.
 
Plays and sounds great and the original finish is in great cosmetic shape overall, except for two notable dings on the back of the neck and surface scratches here and there.
 
Comes with its original hardshell case.
