Anybody got one of these heads? How do they sound? I noticed they have a solid state preamp and was wondering how they compare to the SVT-2PRO. I'm going to Dallas this weekend to try one out. I'm getting a SVT-410HLF cabinet and thought I would get the 350H to complete the "Classic Series" rig. I will try both before buying but I wanted some feedback from anyone with experence or knowledge of this head.
