I recently started jamming with a great bunch of guys, that happen to play progressive metal. The problem is the guitarist play way to loud. They both have 4x12's with 200 watt heads and they sound awesome. I have a GK 2001 rb and a GK Neo 410 and I can barely keep up with them. I have asked them to turn down and they said that they have to play loud to hear themselves over the drummer. So, I guess if I want to keep playing with them i going to have to invest in another 410. I just recently downsized to go figure. So my question is this how do you guys out there deal with guitarist that feel they have to play at 11 on their amps? I don't feel that I am asking to much from them.
