Pure, unfiltered Marshall valve tone in a versatile 1x12 package. Driven by classic EL34 tubes and a 12" Celestion speaker, the DSL40C delivers everything from warm vintage JTM45 cleans to aggressive, high-gain JCM800 roar. With dual foot-switchable channels (Classic Gain and Ultra Gain) each featuring two modes, Pentode/Triode power reduction (40W down to 20W), and built-in studio-quality digital reverb, this amp is equally suited for bedroom practice, studio tracking, or blasting through gig venues.

  • All-tube construction (4x 12AX7 preamp, 2x EL34 power tubes).
  • Pentode/Triode half-power switch for cranked tube tone at lower volumes.
  • Celestion Seventy 80 speaker with FX loop and footswitch included.
