Nothing produces that classic "British" sound like a Marshall amplifier, whether it's a combo or head and cab configuration. The Studio Vintage is based on the amp that first defined rock ‘n’ roll in the 60s, the famed 1959SLP.Combining the raw power and authentic voice of classic rock into a compact 20W amp, it stays faithful to the original with its Plexi design and all-valve tone. The SV20H is an all valve handbuilt amp designed and built in the UK, to accurately recreate the classic Marshall tone. From saturated blues tones to biting leads for classic rock, you'll be hard pressed to tell it apart from a 1959SLP. It also has a handy power reduction circuit so you can drop from 20W to 5W and practice with cranked-up tones at low volume at home.
