Marshall DSL-100H 100w 2-channel guitar head

Marshall DSL-100H


The Marshall DSL-100H builds on the sounds and features of the JCM2000 DSL100 amplifier and adds digital reverb, even more tone adjustment, and the ability to switch between 50W and 100W output.

The mindset behind the Marshall DSL100H is a simple one and obviously identical to that of the original Marshall JCM2000 DSL100 head – combine the world-renowned EL34 driven power- stage of the 1959 Super Lead Plexi (SLP) 100W head with a dual channel valve preamp, giving you two footswitchable Super Leads in one. Then, for good measure, add a built-in, studio-quality, digital spring Reverb plus extra preamp gain that can take you into JCM800 2203 territory and far beyond it. Hence the name DSL – Dual Super Lead.

The Marshall DSL-100H 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 Equalisation 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.

The Marshall DSL-100H’s power section features 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 all-round tonal and gain versatility makes both the DSL100H & DSL40C superb and flexible performance tools for today’s most demanding playing situations and you can rest assured it is packed full of our famed Marshall tone.

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.
