Being an Australian and hence having limited access to affordable heads (damn import prices), I've had to narrow it down to these three for my new rig. However, I have no idea which to choose. If it helps, the cabs will probably be inexpensive for now, perhaps Behringer or such. I play in a metal band that attemps to play classier music with clean/experimental/soft instrumental interludes as well as Meshuggah style heaviness. Also, I will be playing a Warwick Corvette through a Gt-6b. Any advice?
