I bought the BG250-112 when it first came out. I use it for upright and electric basses. It works great in every setting. Medium volume to kind of loud bands are no problem for this amp. It can't hang with 2 Marshall stacks blasting on 11, but it can hang with a loud-ish club band. Works really well for upright bass with lower volume acoustic bands. I use it as my monitor for larger stages and showrooms when going direct. It easily handles all my club gigs. Going strong for 3 years now without a glitch.
