Korg Poly800/EX800 Users

Dear Poly-Freaks and Fans,

Has anyone done - and can tell me how it works - a non destructive mod
of the Poly 800? I'd like to mod my new Poly without breaking the VRs.
I've seen pictures and heard sounds of this modification before. Its
fat! There's a switch above the pots which lets you choose whether the
signal runs through the VRs or the freshly soldered pots you just
built in. Very nice idea I think since you can always go back to the
old sound and you don't limit your midi-capabilities :)

Any help will be greatly appreciated
