Recently went to the local GC to kill some time and tried out the Ampeg V4B reissue and matching cab. Loved that Ampeg round sound. So, started considering how to get it. Duh, buy an SVT you might say. Well, yeah, but I don't have 1700 to part with. Dont even have 1200 to part with for the V4b. So, started looking at the Portaflex heads. Played through several Ampeg cabs all the way up to the fridge. Still just didn't feel I was getting anywhere near to that tone. Went and tried the BA210 combo. Almost immediately got the tone I was looking for. It's not exactly that big, round, pillow of tube tone, but it's really close to my ear. So am I crazy that I'm hearing such a huge tonal difference between the Portaflex heads and the BA series? Has anyone else noticed this?
