Fender tweed

The amplifiers are named for the cloth covering, which consists of varnished cotton twill, incorrectly called tweed because of its feel and appearance.

They are praised for their sound, their circuitry being considered "hallowed ground".

Beginning in 1990, Fender began to utilize the tweed covering once again, starting with the '59 Bassman Reissue.

[5] The Fender Blues Deluxe and Blues DeVille and their later reissues were also available in tweed,[6] as well as the Custom Shop reissues of several of the Tweed Era amplifiers.

In 2012, Fender introduced its first "Signature series"; Eric Clapton helped design the "EC" series of three amplifiers, including the Vibro-Champ, based on the five-watt amplifier "allegedly" used for the recording of Layla and Other Assorted Love Songs.
