This fuse holder is similar to the fuse holders used on the Fender Tweed Series Amplifiers back in the late 1940's to the early 1960's. This fuse holder will serve as an excellent replacement for any Fender Tweed Amplifier in need of a repair. Amplifiers like the Fender Tweed Champ, Fender Tweed Princeton, Fender Tweed Deluxe, and so on. In the event your original fuse holder cap was lost or damaged, the cap on this fuse holder will fit on your original fuse holder. Easy to install and ready to serve you for the years to come!
