Obsessive as I am, I did another rewire (I've done at least 3) on my express clone to try to further reduce the hum and fix a "sound" that I was getting during sustained notes (note rings, low end fades out and back in). I have not had much time to play the amp, but the hum seems to have gone way down and the "sound" is mostly cured.
details are on the link above.
