We have a Fender Rumble 350 bass amp that is not being used. We are wondering if we can run our singer through it, without a PA system. Simply a studio microphone straight into the "line out". Might be redundant, but were new to music hardware and wanted to know before plugging anything in and risking possible damage? From what I've read, with a PA system its possible but just lower quality. Anybody know if its safe and possible without a PA system to run the mic straight into a fender rumble 350 bass amp?
