Korg Poly 800 with Moog Slayer Mod

” Korg Poly-800 mk1 with Moog Slayer mod (filter cutoff, resonance, and FM) and filter switch to choose between 12db and 24db filter options. The internal battery was replaced by a previous owner (probably when the moog slayer mods were done). Works great and is an underrated vintage synth capable of some very warm sounds.” Click here to search for synths on eBay
