This was one spotted on ricardo.ch, by swissdoc. According to the listing it's a:
"C64 SID Synthesizer 4x SID Chip
1x Midi In
1x Midi Out
4x Audio Out Mono je SID Chip 1 Audio Out"
If anyone knows more about this one or B.H.Z let us know! This is the first B.H.Z. post on the site.
Curious if this is a one off Midibox based SID.
Update: confirmed this is Midibox based. Now checking on what the B.H.Z. stands for. Maybe the initials of the maker.
