Marshall DSL20CR Rør Guitar Combo

Marshall DSL20CR — 20-Watt All-Tube Combo Amp with Authentic British Valve Tone

This 20-watt, 1x12 tube combo amplifier is built for guitarists who want genuine valve character in a portable format. The unit pairs a Classic Gain channel with an Ultra Gain channel, covering cleans, crunch, and high-gain saturation. Switchable 20W/10W power modes let it move from home practice to club stages. A 12-inch Celestion Seventy-80 speaker delivers the punch that this legendary brand is famous for.

Softube Emulated Output, Resonance Control, and Tone Shift

What sets this model apart is its Softube emulated line output, which reproduces the iconic 1960 cabinet for direct recording or silent practice through headphones. A dedicated Resonance control replaces the original DSL's fixed Deep switch. The front-panel Tone Shift button scoops the midrange for modern metal voicings, and the studio-grade digital reverb adds dimension.

All-Valve Power Stage — 20W Output with EL34 Tubes

The all-tube signal path is the heart of this combo's tone. Two EL34 power tubes drive the 20-watt output stage, delivering the warm breakup that has defined British rock. Three ECC83 (12AX7) preamp tubes provide the harmonic complexity that modeling amps struggle to replicate. A switchable power mode drops output to roughly 10 watts for bedroom-friendly volume.

• Power Output: 20 W (switchable to ~10 W low-power mode) — full valve tone at any volume
• Power Tubes: 2x EL34 — classic British power-tube compression and growl
• Included are 3x ECC83 (12AX7) preamp tubes that provide articulate touch sensitivity across both channels.

Two Channels and Refined EQ for Total Tonal Control

The two channels — Classic Gain and Ultra Gain — each have independent Volume and Gain controls. A shared three-band EQ (Treble, Middle, Bass) is paired with Presence and Resonance controls for precise power-stage shaping, while the Tone Shift button offers a mid-scooped voicing for contemporary high-gain styles.

• Channel options include 2 (Classic Gain, Ultra Gain), which are footswitchable.
• EQ Controls: Treble, Middle, Bass, Presence, Resonance — full-range tone shaping from clean to high-gain
• Tone Shift + Reverb: Mid-scoop voicing and onboard digital reverb — modern metal voicings and spatial depth

Celestion Speaker, FX Loop, and Direct Recording Output

A 12-inch Celestion Seventy-80 speaker handles the on-stage sound. The rear-panel series effects loop integrates time-based and modulation pedals, while the Softube emulated line output sends a cabinet-simulated signal to an audio interface or headphones. Three speaker outputs support 8 or 16-ohm external cabinets, and the included 2-way footswitch handles channel switching and FX-loop on/off.

• Speaker: 1x 12" Celestion Seventy-80 — full-range British-voiced driver
• Effects Loop: Series FX loop — integrates modulation and time-based pedals post-preamp
• Direct recording is managed by Softube 1960 cabinet simulation for silent practice via 3.5 mm jack.

Home Players, Recording Guitarists, and Small-Stage Rockers

This combo is the right choice for guitarists who need authentic all-tube tone at manageable volumes. Home players benefit from the 10W mode and Softube emulated output for late-night practice. Recording musicians capture genuine valve tone into an audio interface. Small-stage performers get footswitchable channels and enough volume for clubs.

The DSL Heritage — From JCM2000 to Modern Reissue

Marshall has shaped electric guitar sound since 1962, when founder Jim Marshall opened his shop in Milton Keynes. The original JCM2000 Dual Super Lead (DSL) series launched in 1997 and became a backline staple. This reissue revives that DSL lineage with modern refinements — Softube, Resonance, and Tone Shift — while keeping the all-tube EL34 voice.
