Díaz CD-100 Amp Head
Diaz · amplifier
The Cesar Diaz CD-100 is a hand-built amplifier head running roughly 130 watts through four 6L6 output tubes, sharing structural similarities with a Fender silverface Twin Reverb but voiced with a tighter low end through Diazs own modifications, plus a footswitchable mid boost for extra punch on lead lines. Cesar Diaz spent over three decades building, modifying and repairing amplifiers for artists including Bob Dylan, The Rolling Stones, Stevie Ray Vaughan and Jeff Beck. Warren Haynes uses a CD-100 built in the early 1990s as a constant across every project he plays in, guitar or otherwise.
