Marshall DSL20HR 20-watt Guitar Tube Head

Designed to replace the 15W model in the company's DSL line, the Marshall Amplification DSL20HR is a three-valve amplifier head for electric guitar. It features two channels with separate controls for volume and gain, a comprehensive equalization section, and reverb. The Dual Super Lead (DSL) offers Classic Gain and Ultra Gain channels.

Though the amplifier offers many of the same features of the 15W model, this amplifier improves upon the design of the DSL20HR in several ways. For instance, the power-reduction switch has received an upgrade. Whereas the 15W model sported a back panel selector that flipped between pentode and triode operation, the DSL20HR boasts a front-panel rocker switch that works directly with the transformer, rather than the tubes. Thus, when you switch from 20W to 10W, you'll experience no shift in tone.

On the rear panel, you'll note three 1/4" outputs supporting various impedances. You can make this amplifier work with 16- or 8-Ohm cabinets. An emulated output offers a cabinet simulation design by Softube and can be used in recording scenarios. You'll note the FX loop for introducing pedals and external gear into the amp's signal path as well as an auxiliary input for jamming along to your favorite tunes.

Tonally, this amplifier is similar to the 15W version, with a wide array of classic Marshall timbres on hand. Another key difference, however, is the look of the DSL20HR. With elephant-grade tolex employed in its construction, you'll find it resembles classic British-built Marshall combos. The DSL20HR ships with a power cord and a dual footswitch for Classic/Ultra channel selection and reverb on/off.
