Funny I always thought the Ampeg sound was from a B-15 , Then the SVT later .
The sound on most records is a B-15 . I've always gravitated to the B-15 tone , even when I had a SVT I just tried to make it sound like a huge B-15
Even a couple of Van Halen albums were recorded using a B50R .
I'm with you. I run an SVT-CL.
But OP (unless I misread his question) is satisfied with the little combo. That seems to be Ampeg enough for him, which is fine. To that end, the PF series should get him in the ballpark.
