Home / Marshall DSL20HR 20W Guitar Tube Head Amplifier
The Marshall DSL20HR is designed for those who need the full, rich tone of a valve amp in a compact and portable format. From the moment you plug in, the DSL provides you with the functionality you need to take your sound from rehearsal to the studio with confidence. Designed and engineered in the UK, this head delivers the legendary Marshall roar without the massive footprint of a full-sized stack.
Pure Valve Power: Driven by three ECC83 preamp valves (including a dedicated phase splitter) and two EL34 power amp valves, providing the organic gain and responsive feel that tube purists demand.
Two Masterful Channels: Features two footswitchable channels—Classic Gain and Ultra Gain. Switch from shimmering cleans to the high-gain "bite" and "punch" that has defined rock for decades.
Tone Sculpting Mastery: Beyond the standard 3-band EQ, the DSL20HR features additional Presence and Resonance controls. These allow you to adjust the high-end sparkle and low-end "thump" respectively, ensuring your tone cuts through any mix.
Variable Power Levels: Choose between 20W or 10W at the flick of a switch. This allows you to drive the valves harder at lower volumes, making it perfect for both recording and small-stage performances.
Professional Connectivity: Equipped with a series effects loop, a 3.5mm emulated line out for silent recording, and an Aux-in for jamming with backing tracks.
All-Valve Circuitry: Genuine tube technology for professional harmonic richness.
Triple Speaker Outputs: Features three 1/4" jack sockets supporting 16Ω and 8Ω loads, giving you the flexibility to drive a variety of speaker cabinets.
Digital Reverb: Includes a high-quality studio-grade digital reverb for added spatial depth.
Compact and Portable: Weighing only 9.7 kg, it is exceptionally easy to transport between sessions.
