I used one about two weeks ago on a recording session with my upright and 64-P-bass and was so blown away I bought the company. ... No I didn't, I bought one U5 and I'm still blown away. ... Curious if anyone out there is gigging with theirs. ... I'm more into notch filtering than bass, treble, mid controls and really like that this unit delivers. ... I do mostly jazz and blues gigs using 1 or 2 Agui 12" with a 350-head. ... Who's using theirs live and with what?
