Instructions for adding extra SIDs to C64?

Hi,

I'd love to modify one of my C64s to have four SIDs to be able to use the 4SID-version of SID-Wizard. I'm handy with a soldering iron and with analog electronics, but not so with digital stuff and physically modding/mounting stuff.

Are there any instructions on how to perform such a mod? My idea is to have 4 separate outputs (one for each SID) with protective buffers for each output. The idea isn't to release 4SID C64 executables but rather use the system as a "C64 mega music workstation" for general music making.

BTW I'd pay good money for a ready-made 4SID C64 :)

I guess you could take an existing stereo SID schematic/pcb and expand it to four.
