Korg Poly800/EX800 Users

I know & appreciate what you're saying, and normally I wouldn't start modding an analogue, hybrid or not, and I've owned a fair few over the years.

I got this cheap and as I'm already modding it for the filter, FM, 12db mods etc then why not.  As mentioned I'm not thinking of taking the chorus out I just want to tap in before it really and as there's loads of space inside I can mount an overdrive board.

because it's generally cheap it does have some excellent mods which to be honest sound like they improve it a lot and I don't believe really destroy any value as such.

...and anyway.... I need a project now that I have kids and don't get out playing much ;)
