    Actually all Pro Reverbs are CBS, sorry to nit pick.

    That said the BF circuit didn't change until late 69 according to the fender amp field guide. One thing added was a bias balance pot instead of the standard bias pot. That is easily reversed.

    I have a 68 Pro that had the bias balance AND cathode bias caps, and suppressor caps too. Definitely not Blackface.

    Yes, there seems to be a big difference
