Is the basic tonality of the SVT450H similar to the pre/amp sections of the BA series of combo's? After years of playing expensive, hifi brands, I found myself really liking the basic tone of the ampeg BA115HP and BA210HP. I just shake my head, but if it works it works right? I've walked into Guitar Center on several occasions to try basses including one that I own only to realize it was the amp I was liking. The BA's are not big enough for my purposes, so I was thinking a SVT450H with a SVT 48HE and SVT 115E that I already have would be like a BA115/BA210 on steroids. Am I on the right track? Also, is there a appreciable difference with the US made vs Vietnam made Ampegs?
