I saw a CL ad for a b25 Ampeg cab that has 2 15's in it. Was this cab made for bass or guitar? Or is it one of those 70's kind of "whatever" cabs? Would this thing (stock) handle a 5 string bass and a V4 with any good results? I usually have good PA support so I wouldn't need incredibly loud volume from it, but still, some of those old cabs weren't designed like a modern high power one. Any thoughts? Will it get the job done at less than insane stage volumes? Thanks.
