Hello guys, I'm a very inexperienced bassist (I've been playing for just under a month) and I'm in need of a new amp. Ideally I'd like a stack/half stack and I've seen a half that I'm interested in. It's a Gallien Krueger Backline 600 combined with a GK 410 MBX cab. The head is 300 watts and 4 ohms whereas the cab is 400 watts and 8 ohms. What problems can this cause and how can I prevent them? Here's a link to the stack http://www.soundslive.co.uk/product~name~Gallien-Krueger-BL600-+-410MBX-Bass-Stack~ID~17628.asp Cheers.
