Simple question. I've got 700rb ii and gk neo 412 cab plugged with gk speakon cab so I can use the biamp feature. However, I don't use the tweeter. My tweeter knob is all the way anti clockwise because I often use fuzz and od and just prefer the sound. Now for the question. Is there a difference in sound if I set the cab to full range rather than biamp since I have no plans to use the tweeter or is it the same? Do speakers get a different freq range with full range or do they get the same range as with bi amp?
