# Korg Poly-800 with Moog slayer mod
“Hi there. I am selling a Korg Poly 800 Mark 1 synthesiser with the Moog Slayer filter and resonance modification. It is the rare reverse keys version, which looks a bit cooler than the normal version.
I’m selling this because I’m a student, and I’m running out of space and money. I’m going to sell some gear, then maybe replace it when I’m a millionaire.
The Moog slayer mod does 2 cool things. It provides 2 nobs for control of filter cutoff and resonance, so you can tweak on the fly rather than mess around with buttons.
The other thing it does is increase the range of the resonance, taking it to ear-bleeding levels of self oscillation. You have to hear it to believe it – it’s terrifying.
It is not in perfect cosmetic condition, as I’ve always been more concerned with how it sounds. The biggest problem is that an E key is damaged. It’s still playable, but rather tricky. Also, the bending joystick has no cover, but this does not affect functionality. I have removed the covers for the moog slayer pots as I am replacing them. More photos this week.
The synth will come with the original PSU and some batteries, which are necessary for patch storage.” Link
