About the amp:

The Marshall DSL20HR and DSL20C are part of the DSL Series of amplifiers. These are all-valve heads and combos that we have all come to love. They deliver that classic Marshall tone and excellent build quality.

These amplifiers all offer a Classic and Ultra Gain Channel. This gives musicians the option of pristine cleans right through to aggressive overdrives. Each channel also has a dedicated Master Volume control. Also of note is that all the models in the range also provide an emulated output for recording purposes.

For us, one of the best features of this amp is the power reduction switch. Being able to drive the amp hard at low volumes is extremely useful. We love it!


  • 10W/20W Guitar Amplifier Head.
  • 10” Celestion Ten-30 speaker.
  • 2 x Channels (Classic Gain & Ultra Gain).
