I'm planning on coupling it with the Peavy TVX 410 but my question is, is it worth the extra 80 or so bucks for the 700 or will the 450 work? I will be using it in a country southern rock band with two electric guitars using nothing bigger than half stacks, and an acoustic guitar and drums. And then me. I just want to make sure I have enough head room and to me if the 700 is gonna be worth the extra bucks I'd like to know why since that's the way I'd probably go. Thanks guys!
