Hey, I'm getting a pro setup for my universe, and am planning on using 9-46+60 gauge strings on it if i go with standard tuning, but I'm wondering if I should try a half step down? I dont want to seem like I'm just doing what my favorite bands do, but it seems Bb is popular among 7 stringers. The reason I want to tune to standard is I want to have one guitar in standard tuning, but I have a feeling Bb might sound a bit better, but the tonality change might be negligible. Any advice? Thanks Ryan PS: this is primarily going to be for metal in the style of Nevermore/ Dream Theater, and also, would Bb make it harder to incorporate keys?
