We have had many requests for modifications kits for our korg Poly800 mods, mainly due to the fact that Poly800's are pretty big and therefore expensive to ship for modding, especially from outside the UK. As a result we have put together a limited number of Korg Poly800 'polybeast' mod kits.

The kit includes all the necessary parts and an 11 page manual detailing the installation of all the modifications found on our standard 'Polybeast' mods, on a Poly800 mk1. The EX800 and the Poly700 mkII have the same motherboard so the actual mods are the same and you can work from this guide, but obviously the controls positioning will differ. We do not supply a specific EX800 or Poly800 mkII kit.
More details and demos of the kind of sounds these mods are capable of producing can be found over on the main Poly800 mod page HERE.

Mods include:

Cutoff and Resonance knobs
12dB / 24dB Filter response switch
VCF CV input
External Audio input
External Audio Path Switch
Input Level Knob
VCF FM source selector
VCF FM amount knob

While we have produced diagrams and attempted to make the installation as simple and pain free as possible, this is probably not a project for an absolute beginner. You should at least have some experience of soldering and working with various electronic components. Having modified a synth, drum machine or toy before would be a definite advantage.

You will also need some wire, a soldering iron, some solder, wire cutters, a drill with various size bits, and we’d also recommend some solder wick or a solder sucker to remove components from the circuitboard, although they’re not strictly necessary.

This kit does NOT contain the data entry knob. The data entry knob can be bought separately from HERE.

You can choose between the kit having green knob caps, which would be suitable for a Poly800 mkI, or blue caps which would look better on a Poly800 mkII or EX800.

PLEASE NOTE: We will not supply the installation guide, without the parts kit.
