I have the opportunity to buy a Fender Deluxe Reverb blackface... The seller sent me a couple of pics via email, and it looks like it's in perfect condition. I think it even looks like it is a Reissue... The seller seems to know next to nothing about amps, and cannot tell me if it is a vintage mint amp or a RI. The s/n is AC025812. The inside label reads: mention "Deluxe Reverb Amp - Model AB763". The spkr is an Eminence. I have no more info. What do you guys reckon? Is that an oldie or not? Thanks !!
