After G.E. left the band, Díaz played some 50 dates with Dylan, including a show for the Lifetime Achievement Grammy Dylan won in 1991, and in 1993 left Dylan to devote his time to his amplifier business.

Diaz Musical Products

Díaz began to manufacture amplifiers and guitar effects—hand-made, in small production runs. His amplifiers are built in the Fender tradition; the Classic Twin-100, for instance, is a 100-watt two channel amp inspired by the Fender Twin. Effects include a spring reverb unit. His Tremodillo tremolo pedal is highly sought after. In 1992 Cesar performed in and helped to design "The Ultimate Guitar tech" film. The film was a very well received guitar tech industrial training film teaching the best way to change and tune strings on the guitar, to fixing tube amplifiers. Filmed, produced and edited by Leonard J Eisenberg, the Jimi Hendrix photographer
