Fender Tweed

Although many reissues from Fender have been released and scores of companies offer replicas, Tweed generally refers to the amps that Fender manufactured in the late 1940s through the 1950s. Named for their "tweed" covering over the cabinet, these amps are highly collectible and have a highly sought after tone. Although their were numerous models from that era, the most popular were the Fender Champ, Fender Princeton, Fender Harvard (rare), Fender Deluxe, Fender Bassman and the highly popular Fender Twin.

Because the circuits of these Fender amp models changed slightly over time, many enthusiasts include the schematic number to further identify a specific amplifier. Terms like Fender Champ 5F1, Fender Princeton 5D2 and Fender Bassman 5F6 all refer to specific model revisions.
