About combo amps..... I have tried quite a few combo amps and a while back bought a BA115 Ampeg. Which I thought sounded not too bad for what it is. I've tried quite a few others. But I've noticed on a lot of these amps you get pretty good bottom end and lows...but.....often the lows are either too "punchy' or they are "hollow' sounding..... (I'm playing an Ibby SR500 with D'addario flats......and my Jag SS has same strings.)... Lots of tone tweaks on the Ampeg and the basses. And I can get them to sound pretty good. But is there a combo amp that has bit more "solid" -sounding bottom end? Sweetly "solid" without being "punchy", "annoying" ..or "virtual warehouse air"?
