Carvin Corporation was founded by Lowell Kiesel in his Los Angeles garage in 1946. The first tube amps were produced in 1948, with later models featuring 6V6 and 5Y3 rectifier tubes. Mother of Pearl covering and hand wired chassis were the norm of that day with Jensen speakers introduced a few years later. Dedicated bass amplifiers began in the 1960s. Popular models in the 1980s included the X100B guitar amp, which was used by Frank Zappa, Steve Vai and Craig Chaquico. Other popular models in the 1990s included the Quad-X preamp, Redline bass amps, Nomad, Belair and Steve Vai’s Legacy amplifier, which is still produced today in its 3rd generation.
