I have the problem of not being able to hear myself when we practice (my band, that is) We play like Dream Theater Mixed with Motley Crue. Normally my Hartke 120Watt Kickback 10 does the job but now we have 2 guitarists with 60 watts each and 2 drummers who play louder than most on their own. They both use double bass and both have invested huge amounts of money in their sets. So I am obviously looking to upgrade my rig. I really like Gallien-Krueger and am trying to decide between the Backline 250or the Backline 600, or maybe even the Behringer BX300 head (450 watts for 250 bucks is awful intriguing). And to top that what cabinet should I get, The GK410 or GK115. Or do I go with The Behringer and get one of their cabs to handle the power. Someone please help!
