I have been using an older Ampeg B4 bought cheaply through a 410HLF for several months and have found "the tone" I had been looking for. The lug factor has been a bit of a pain but the tone makes up for it. Unfortunately, it stopped working and needs repairs, something that I may eventually get around to but rather than sink more money and time into this, I would like to buy a new head for warranty purposes and to get some other features I really want that the B4 doesn't have. My top candidate is the SVT-7 Pro. I like the light weight, 1 tube preamp, the headphones and aux inputs and the full kilowatt headroom that I got used to with the B4. The other option that appears to match without the aux inputs is the SVT-4 Pro which even though it has all of the great output options, I never needed them. (I bridged into the 410 which was plenty of volume). I never needed to go 2 ohms. But I would really prefer the 7 over the 4 if the tone closely matched my old SS B4. I have read that the SVT-7 and the SVT-4 are similar in tone and I have also read tone similiarities between the SVT-4 and the B4 so logic would tell me the B4 and the SVT-7 are similar. I am not close to a dealer and will be ordering online so I am relying on first-hand experience with the B4 and the SVT-7. Can anyone tell me conclusively from their experience that a new SVT-7 will be the amp of my dreams and that I should order it already for chrissakes? Thanks in advance.
