I've owned a B100R a while back and though it is louder than alot of other 100 watt combos, I had to crank it up pretty high at rehearsals. I did like the tone alot as well as the durability and reliability. So I'm in the market for another Ampeg combo and came across the BA-115. It is a little more affordable and has the RCAs which I need. My only concern is how does the volume of the BA-115 compare to the B100R? They are both rated at 100watts.
