You must have been very lucky finding this thing. I've been searching for years now for something similar. All I can find are mic/line mixers, nothing suitable (and affordable) for 3 or 4 guitars. And I would really like to avoid having to use 3 DI boxes .
The Palmer DUETTO comes close, but only 2 channels. Palmer Trinity looks nice, but rather expensive.
