In an effort to make my rig a little more portable and useable, I'm getting rid of my old Ampeg 810E and am searching for a good 4x10 with which to replace it. In trade, I've been offered: -Ampeg 410HLF -Ampeg PR-410HLF -Some older Sunn 410, ported at the bottom. I'll be running it with my Mesa 400+. I really dig the Ampeg cab tones, so which one of those two is better, and why? also, anything I should know about the Sunn? thanks!!
