I have an OSB Ampeg 810 that's falling apart. I'm toying the idea of another 810, but I can make any decent cab sound good, so if I find a good rig, I won't miss it. I'm highly considering an Avatar 410 + 210 (8 ohm 410, 4 ohm 210 wired to 16 ohms, total load 5.3 ohms, equal power to each speaker). Having two separate cabs will defiantly help me move around. I play through a Genz streamliner and an Ampeg SVT 7 pro. How much loss of volume will I experience with the switch? Tone isn't an issue, I've played and like avatars.
