Okay thanks. The link didn't help me with the pedal issue however. I've messed with the settings I think it's a hardware problem. I haven't looked into the alto but I do see what your saying about the gain and low cut. The qsc and Yamaha are both pretty pricy. If I were to spend that much I'd just go with the Friedman asm. I'm not really sure what route to go. I use a jbl lsr 305 most of the time and like it pretty well. I don't have a complaint about it. Just looking for more volume incase I play with people.
