Several variations on the amp's original design have been produced through the years, including the Twin Reverb, the Super Twin, the Twin Reverb II, and the Twin Reverb '65 Reissue.

They all had the classic features we're familiar with now: heavy steel chassis, chromed control plates, and heavy pine cases covered with tweed fabric.

The finishes were baked in the Kauffman family oven.

They were made in three different sizes, 1×8" (one 8" speaker), 1×10", and 1×15".

The list of artists who've used a Fender guitar amp live or on record is enormous.

It seems as if everyone has used them at some point, including Elvis, Chuck Berry, Buddy Holly, The Beatles, Rolling Stones, Oasis, The Strokes, Radiohead and White Stripes, to name but a few.
