As demand for vintage Fender tube amplifiers had increased, several re-issue models were introduced in 1990, beginning with the tweed '59 Bassman amplifier, the brownface '63 Reverb unit and the brownface '63 Vibroverb.
Fender made great efforts to reproduce the tone and look of the original unit.

The cosmetics incorporated the brown "Tolex" and wheat-colored "Ecru" grill cloth used in 1963, as well as the "flat" Fender logo plate found only on the brownface amps.
Although cosmetically and—more importantly—tonally accurate, there were several notable differences to be found (solid-state rectifier, printed circuit boards, ¼" reverb/vibrato footswitch jack, 3-prong power cord).
A "direct-coupled" oscillator circuit was used for generating the vibrato (albeit with different components).
The noticeably "warmer" reverb sound of a vintage brownface Vibroverb (due to the original reverb send and recovery circuit unique to the Vibroverb) was also present.

A second toggle switch allows the player to disable the Normal channel and the Vibrato effect; the preamp gain is increased, and more distortion and sustain is available.
This version of the amplifier has a fifteen-inch Eminence speaker and point-to-point wiring.
