I recently picked up a Fender Rumble 100 combo amp. Im looking for a small lightweight combo rig that would suffice in a small bar. But with a couple of gigs coming up that are outdoors and a couple that are inside a larger then usual for my band room, I'm feeling my doubts about this rig. The singer in our band once expressed his concern with sharing the PA with my bass. I think he thought that the pure sound of his vocals through the PA would be muddled with my bass sharing the speakers of the PA. Is this a legit concern of his or is he misguided in his fear?
