The Marshall DSL50 has been my amp of choice for years now, and I’m still finding new sounds inside it. It’s a very versatile yet straightforward beastie which can pump out hard rock and metal tones as well as blues, jazz, classic rock… and it does it while preserving the character of whichever guitar you plug into it. Marshall has revamped the DSL line with several new amps.
Check out the new DSL100H, for instance. It has the same exact features and valves as the DSL100, but with an added Resonance control, digital reverb instead of spring, and a rear panel Pentode/Triode switch which drops the output down to 50 watts from 100. It also comes supplied with a two-way footswitch for channel switching and reverb on/off.
