This is Rory's Fender "Pro Amp" Tweed, 1x15 inch combo. It is the early spec, Square logo period, and is dated to October 1954. This amp we believe was primarily used as a recording amplifier, but has been used live as well. It has had a speaker upgrade, to something with a way more substantial cone, and needless to say.. It sounds amazing. These amplifiers are very rare and are not seen very often on the Vintage market.
