Hello, I play guitar in a band and we are trying to upgrade our bass setup. Right now we have a Peavey Firebass and a Hartke 4x10. It never seems to be loud enough for us when we play shows. Can anyone suggest a good amp and cab setup? It doesnt matter whether it is a head, or a power amp/preamp. We are all in college and money is tight, but we still want to get something that will last us and certainly get the job done.
