I've got 4 Millennia MM99 op amp blocks that were designed by Fred Forsell. Looks like I found something to do with them. I guess I'll build some A12's, or J99's with them.
An 8 channel unit with some A12's for toms and kick + C84's for snare and overheads would be a great drum unit. Maybe a few N72's in there too.
And of course I'll need another 8 channels for other instruments. Then I can tell people I built my own preamps. Cool!
