Hey Duncan, I just finished a 5E8A Tweed Twin build the other day. I haven't put it into a headshell yet but I'll be starting it soon. So far I've been running it with a avatar 2x12 with v30's and a 4x12 with eminence legends and it sounds fantastic. Nik had the sound clips I sent him posted on the ceriatone website so you can go there to check out what it sounds like. It's a fantastic amp.
