Product Description for the Marshall DSL40C

The Marshall DSL40C is a sturdy, gig-ready 40-watt workhorse boasting two EL34 power valves, a Celestion speaker, and the exact same front and rear panel features as the DSL100H -- including the Triode (Half Power) option which drops the DSL40C's output to 20 watts.

Combine the world-renowned EL34-driven power stage of the 1959 Super Lead Plexi (SLP) head with a dual channel valve preamp, giving you two footswitchable super leads in one. Then add a studio-quality digital spring reverb, plus extra preamp gain that can take you into JCM800 2203 territory and far beyond, and you get the DSL: Dual Super Lead. The DSL40C delivers famed Marshall tone in a 40-watt, 1x12" combo form, housing a custom-voiced Celestion speaker.

The DSL40C features two footswitchable channels (footswitch supplied) named 'Classic Gain' and 'Ultra Gain' -- each with two modes, selectable via a front-panel button. As their names imply, each channel has a very different character. Classic Gain takes you from a 1959 style clean to the snarl of a JCM800 2203, and everything in between via its Clean/Crunch mode button. 'Ultra Gain,' on the other hand, takes you from a hot-rodded 2203 vibe to an even higher gain response with additional mid-boost, via its Lead 1/Lead 2, mode switch.

Both channels share a passive three-band EQ with controls for Bass, Middle and Treble. The Equalization section also features a 'Tone Shift' button which, when activated (pushed in), shifts out the mid frequencies -- making the amp ideal for brutal, modern metal tones, especially when combined with high gain settings. Each channel also has its own individual reverb level control for the built-in studio quality digital spring reverb, This effect can be switched on/off via the supplied footswitch.

In the power section, you'll find controls for resonance and presence. Resonance adds a variable bass boost to your sound without muddying it up, while the presence adds high end. The ability to select either full output power or half-power via the Pentode/Triode switch on the rear panel, adds further to your DSL's already impressive feature set. The tonal and gain versatility makes the DSL40C a superb and flexible performance tool for today's most demanding playing situations.
