# Korg Poly 800 Moog Slayer
“Modified Korg Poly 800 synthesizer:
This item is a great working condition Korg Poly 800 synthesizer professionally modified by Class A Electronics, LLC/Diabolical Devices. This is a cool synthesizer because the VCF (filter) is actually analog. These have a great 80′s/Video Game sound. We have added the popular “Moog Slayer” mods which adds hard wired controls for VCF Cutoff and Reso. We have also added a VCF audio input with level control and Blue 7-segment displays.
This synthesizer originally retained patch data using D cell batteries that go into the back. We have added a lithium battery to the mother board, the D cells will still power the keyboard if desired (no batteries included). Right now there are only the patches I created to test new battery and mods. There are some great 3rd party editors for this keyboard that allow you to create patches on your computer. There are a couple of discolored spots on the case (see pics) otherwise it’s in great physical condition.” Link
