# Korg EX-800 Moog Slayer
“Up for sale is a vintage Korg EX-800 Programmable Polyphonic Synthe Module. This is essentially the rackmount version of the Poly-800. I have modified this synth with added control knobs for Filter Cutoff and Resonance (known as the Moog Slayer Filter Mod) as well as a knob to modulate the filter’s frequency via DCO 1 (known as the FM-800 Mod). This unit is in very good working condition. The filter mod sounds amazing and makes the unit capable of some serious speaker-blowing bass. The WRITE button needs to be pressed/tapped hard to register, but still functions. Number keys are a bit sensitive, but work just fine. Some blemishes & discoloration here and there, but nothing major. I have recently replaced the internal battery, so most of the patch bank is blank except for a few that I have programmed and saved since replacing battery. The new battery should be good for a few years. I do not have the rack ears or manual for this synth. I will include a compatible Radio Shack power supply.” Link
