Hey guys, Well I finally have the money to buy a head for my Shroeder. The toss up is between a Genz Benz 1200 and a Mesa 400+. I play music that is generally of the heavier variety and so I was wondering what would be better. A big consideration is how well these amps will be able to reproduce my F# string (thats F#, B, E, A etc) on my seven string. Would the tubes on the 400+ be a little slow? I also live in Australia and so the amp would need to be cahnged from 120v to 240v. Doing this on the Mesa is a matter of soldering a few wires, but what would be involved in converting the GB 1200? Maybe someone from GB could chime in? Id really appreciate it... Thanks heaps guys!
