I didn't know how to vote, I like 'em -- but, didn't feel so strongly in either direction. My 1st experience with Sans Amp was in the studio with a BDDI. At first -- I absolutely LOVED, LOVED, LOVED this lil gem. But, upon playback & further inspection -- I (along with the producer/engineer) really started hearing too much grind & we ditched it for the rest of the session. I've tried to like the PBDDI a few times, but it just seemed "lacking" compared to the BDDI. I don't know if that was just my ears or what, but I never got a great vibe from it -- so, it never stayed.
Now I've got myself a VT Bass (like almost every other TB'er) & I really enjoy it. I've used it going into SWR W'man's 12, Ampeg SVT > Ampeg 8x10, and I've even used it with my Ampeg B-15R. I recently picked up a Markbass LMT800 & it's great with that too.
All that being said, there have been plenty of times that a Sans Amp product has saved the day. And, maybe I should look into picking up another BDDI.... wait a minute, I think I just figured out which way to vote...
