I recently came across this great Fender Twin Reverb with factory JBL upgrade. The transformer codes say it is a '69 but still has the awesome drip edge trim around the grille like the early silverfaces.. and the tube layout sticker still says AB763. I know you can't go by what the sticker says on these old Fender amps, but from what i can tell the circuit may have been blackfaced like the AB763 when it was last recapped. It sure sounds like it has. I get the most wonderful and extremely satisfying "on the edge of overdrive" tone when pushed really hard with a PAF equipped guitar. The JBL's are a thing of beauty. It may even have the original cones!
