Ok by now most probably gueesed that I'm looking for a tube head. I've tried a SVT CL, and a 300PS. How does the mesa Boogie 400+ compair to these heads? RIght now I'm leaning towards the Ampeg, cause of the different ohm settings. I'm basically looking for a cleanish WARM tube amp. My FBB 5er sounded great through the Ampeg SVT-CL.
