Hey guys! So, I've got this problem with the other guitarist in my band. But before that, a little background on us. We're a five-piece hard rock band from the South East (Philippines) called Imelda [http://soundcloud.com/imeldahardrockombo/great-wall] (not related to the Filipino First Lady at all) and I've been playing with the three other guys (the drummer, the lead guitarist, and our poet-vocalist) for almost five years now. Recently, about 8 or 9 months ago we recruited a second guitarist who was a great common friend between the four of us on the premise that it'd be great having another head in the band. We've been doing shows with him (the new guitarist) for the past few months and well, I'm not really satisfied with his performance. Don't get me wrong, he's a good guitarist but I meant "performance" in a different sense. Now here's where my problem starts. The second guitarist, really likes to turn it up. When I say turn it up, I mean TURN IT UP and he doesn't only do it during rehearsals but also during shows. For a while, we've just shrugged it off as an "adjustment period" but months have passed and it still hasn't changed. We had a rehearsal and show yesterday (as of this writing) and during the rehearsal we told him to turn it down 'cause I couldn't hear myself well, we couldn't hear the other guitarist also. When we told him this, he just told us to "turn it up some more" and of course we didn't want to do that because we'd lose all clarity since it's a big thing for us to be a solid unit with just the right amount of volume for each other. Another problem we have with him is that he tries to be the band leader and takes my responsibilities and forces his ideas on us 'cause it's "cool". I mean, we don't throw ideas out the window like that, we give a try and see if it works. One such idea was to play the outro of one of our songs in double time; we tried it out and it didn't work but he kept on telling us to do it. We just shrugged it off to avoid conflict. Now at the gig, we told him to watch his levels and he cranked his amp again. I told guitarist 1 to tell him to tone down and when he did he just said, "Tell them to turn it up, then." Now, how do I deal with an attitude like this? We've been meaning to talk to him but we're not sure on how to approach him because he might think we're ganging up on him and we wouldn't want that.
