It's a dedicated DI (see attached spec sheet)
No longer made, no idea what it might have originally sold for. I stumbled upon it on e-Bay several hours before the bidding ended and no one had bid, so I thru the opening $40 bid at it! With shipping it was right at $50- less than low/mid priced passive single channel DI
I've used it for bass, electric, and the Taylor/Fishman on the acoustic... happy with all 3
seems a bit phatter than my passive DI's or going it thru a Hi-Z input on the 003 or Presonus
The BBE looks interesting- I've thought about the Bellari's "exciter (I like their stuff.. the "professional" offshoot of Rolls), which I think does something akin to the sonic maximizers
Merry Christmas!
