The Marshall JCM2000 DSL401 is a 40-watt 1×12 combo from the DSL series, positioned as the mid-powered option between the 20-watt 201 and the 100-watt head. At 40 watts the DSL401 has enough output for medium-sized venue work while retaining the touch-sensitive dynamics of a moderately sized EL34 output stage. The full dual-channel preamp with independent three-band EQ per channel makes it one of the most tonally complete mid-power combos Marshall produced during the JCM2000 era.
