Nice!! I have a 61 Concert amp. Those Fender brownface amps are some of the best kept tone secrets out there. The tremlo is to die for. At the moment it's sitting right next to a 97 Matchless DC30 and well able to hold it's own!
Lush, full, total fender tone but plenty of smooth presence. No tube in the rectifier section and does not need one. No reverb, though, that's what the extra brown box is for, if I had it!
