Marshall DSL100HR Guitar Amp Head

The Marshall DSL100HR is a 100 watt all valve head that delivers the classic DSL roar with modern flexibility. With two fully featured channels, switchable power down to 50 watts, independent reverbs and comprehensive connectivity, it is equally at home shaking a stage, tracking in the studio or dialled back for late night practice.

Part of Marshall’s revamped DSL range, the DSL100HR gives you the unmistakable crunch, punch and saturation that made the brand legendary, but with the control and versatility today’s players demand. From sparkling cleans and vintage crunch to searing high gain, this head lets you shape your sound and switch it on the fly.

Classic Marshall Tone with Modern Control

The DSL100HR is built around a traditional all valve design, using ECC83s in the preamp and EL34s in the power section for that unmistakable Marshall growl, bite and harmonic richness. Two split channels, Classic Gain and Ultra Gain, each offer two modes, giving you everything from clean and edge of breakup tones through to tight modern distortion. Shared EQ with presence and resonance controls lets you fine tune the amp to your guitar, playing style and cabinet.

Switchable 100w and 50w Power

With a flick of the rear panel power reduction switch, you can move from the full 100 watt output down to 50 watts. This lets you tailor the amp’s volume and feel to the room without sacrificing tone, so you can enjoy that pushed power amp response in smaller venues, rehearsal spaces or more controlled studio environments.

Performance Ready Features

Two independent master volumes allow you to set separate overall levels and jump between them using a footswitch, making it easy to lift solos above the band without changing your core tone. Each channel has its own reverb control, so you can keep rhythm sounds tight and dry while adding more ambience to leads. An effects loop with on/off switch lets you integrate pedals and rack units cleanly into your signal chain.

Flexible Connectivity and MIDI Control

Five speaker outputs on the rear panel support a wide range of cabinet configurations at 16, 8 or 4 ohms, giving you plenty of options whether you are using a single cab or a full stack. A 3.5 mm emulated line out makes it straightforward to record or send your sound to a PA, while the Aux in allows you to jam along with backing tracks. MIDI in opens up deeper control, enabling you to integrate the DSL100HR into more complex rigs and switch amp functions from compatible MIDI controllers.

• 100w All Valve Power with 50w Reduction - The combination of 100 watt EL34 power and a switchable 50 watt mode means you can go from full stage authority to more manageable levels without compromising tone. Enjoy the same character and response whether you are in a rehearsal room, studio or on a large stage.
• Two Split Channels with Four Modes - Classic Gain and Ultra Gain channels, each with two selectable modes, cover a huge tonal range from clean and crunch to high gain. This gives you multiple core sounds in one head, so you can move between styles and songs with confidence.
• Dual Master Volumes, Independent Reverb and FX Loop - Two master volumes, separate reverbs for each channel and a switchable effects loop provide powerful tools for live performance and tone shaping. Boost solos, tailor ambience per channel and integrate your favourite pedals while keeping your core valve tone intact.
• Comprehensive Connectivity with MIDI and Emulated Out - Five speaker outputs, an emulated line out, Aux in and MIDI in make the DSL100HR easy to drop into any rig. Whether you are running different cabinets, recording direct or controlling the amp via MIDI, you have the flexibility to configure it to your exact needs.
