This is my Midibox MB-6582. It has 8 Commodore 64 6582 SID sound chips in it, to create 4 independent stereo channels.

Currently this box is being rebuilt because I couldn't stand the control surface problems I was hating and the horrible usage of JB Weld to mount the studs on the front panel. It will be much better when I finally get my CNC and can create a new front panel.
