so the serial number is R-004737 but it has a small logo the pins instead of screws the 8-16 8-16 4 ohm 4ohm backplate with attatched power cord but a parallel effects loop because it has 2 knobs instead of 1. So is it a rev G or rev F or a random in the middle one I have been all over boogie board and the only thing I can find is that it might be a left over shell and chassis? The price is 850$ let me know if thats a good revision to buy I don't want to let it slip out I owned a dual rack mount rectifier the thing slayed I am hoping to get that sound but with a more portable head :mrgreen:
