I recently ditched a Behringer 410 (ported) cab for an Ampeg SVT-410HE (sealed). I haven't got a new head yet so I'm still running out of an old Hartke 100w kickback, hooked up to the Ampeg cab. With the Behringer I had a pretty decent tone going dialed in, just through a crappy amp (lots of buzz etc.) Now I've got this Ampeg and can't seem to get it to sound right. I scoop my mids, and like a real throaty sound but no matter what I do there is tons of low end thud over shadowing the natural growl. I've tried taking some of the bass out but it doesn't seem to do any good. The cab just seems really boomy no matter how I EQ. Is this just the nature of sealed cabs? Ampeg cabs?
