I'm sure I don't really need a dubster as most of my gigs are at larger venues that have a P.A. But playing in a reggae band I was always curious about the dubster so when this used one came along at a good price. Well...... I have only used it on two gigs so I need to get quite a few more gigs under my belt with it so that I can get a balanced sound from it using it with the BB2. The times I've used it have been bridged so both cabs were taking the same out put but I think I need to run my power amp in mono mode and have each cab on a different side of the amp so I can blend in the right amount of dubster.
