The SV20C combines the raw power of the 1959SLP and authentic voice of classic rock in a new portable style. The amp that first defined rock ‘n’ roll in the 60s has been revised for the present day, whilst remaining faithful to the original with its Plexi design and all-valve tone. Still considered a classic by scores of legendary guitarists, the SV20C lets you play like your heroes on stage, in the studio and at home.
