I have a chance to pick up some Bag End S-15D cabs. I've read great things about them other than power. One gig I have is a modern country/blues quartet. The guitarist plays through a 40W Fender, and we have an acoustic player/sax with a small amp. The only thing that goes through the PA at many gigs is vocals, kick drum, and sax. Smaller venues (bars, restaurants). My question is this. Will one cab cut it? I have a 15" Trace Elliot that I love, but I am trying to keep as small as I can (and that cab might be part of the trade). I don't want to have to carry two cabs all the time, and the TE works on its own. Thanks.
