  "​Fender Reverb Unit (1961)
   The mighty Reverb Unit produced the sound of surf music. ...
   A genuine tube-driven spring reverb, the device was actually an innovation of the Hammond Organ Company; Fender and other companies licensed the design from Hammond. The 1961 prototype was covered in brown Tolex, with a leather handle, brown knobs (“tone,” “mix” and “dwell”), flat Fender logo and a Tolex-covered front panel rather than grille cloth. The production model had wheat grille cloth in place of the front panel; a second option was white Tolex with maroon grille cloth and white knobs to match the piggyback amps and the Twin. White Tolex with a wheat grille became available in 1962; black Tolex with silver cloth, black panel and white knobs in 1963. A solid-state unit appeared in summer 1966, even though the solid-state amps introduced concurrently all had reverb. A new version was introduced in 1976, with a silver panel and black knobs; very similar to the original and containing several improvements.

   A model even closer to the original, the Reissue ’63 Fender Reverb, was unveiled in 1994 in black, white and brown Tolex. The Custom Tweed Reverb appeared in 1995, with tweed covering to match the concurrent reissue tweed Bassman amps, chrome control panel and black pointer knobs. "
