Silverface with factory pull boost. This is an interesting era for Fender. Pull boost to improve gain, still UL-approved (that means Underwriter’s Laboratories tested it to be almost bulletproof) and an external balance control so you can bias tubes yourself, and now the accessory outlet is now grounded. Still a tube rectifier, too. Original 10” Oxford. This is clean and the reverb and tremolo are working. No footswitch but has an extra Celestion 10” speaker you can have for free, just ask. Handwired in Fullerton, California, USA.
