Gang-
I'm off to test out a Fender Vintage Reissue '63 Reverb Unit that is for sale in my area. Problem is I've never played one so I'm not sure what to look for as far as hum, hiss, pops, etc. I've owned lots of tube amps and of course they are not that quiet, but what would be a big `ole red flag to look for when I'm testing this thing?
Thanks!
