What, no Sovteks on your list?Oh and watch the Rosewoods, don't want to end up on a Fed endangered wood list
Most of my 6L6 amps are vintage Fenders, and the plate voltage those beasts have turns most of the Sovteks into shortlived experiments. I LOVE old RCA and GE 6L6GCs, but they are getting hard to come by. I bought out most of King Electronics' remaining stock of them a few years ago.
I think Gibson's experience with the feds is what brought on these new fretboard materials. I haven't had the chance to try either of them out yet, so I have no idea how they sound or feel.
