The DSL40C is ultra portable, ultra loud, and ultra Marshall.

The critically acclaimed Marshall DSL40C shares most of the same great features as the DSL100H: footswitchable classic/ultra gain channels, rear panel pentode/triode switch (40-watt down to 20-watt) and a rear panel series FX loop.

Unlike the Marshall JCM2000 DSL amps, the DSL40C features footswitchable digital reverb – channel change and reverb on/off footswitch is supplied. The popularity of the DSL40C lies in its feature-packed capability, versatility, its volume-to-size ratio, and its value for money.

The DSL40C is loaded with a single 12" 40 Watt Celestion Seventy 80 speaker.

Comments about Marshall DSL40C 1x12" 40-watt Combo Guitar Amplifier:

I got this amp a few days ago unexpectedly and realized its amazing. I'm going to use it to play things for my school, but I currently use it at home. It has a great classic gain channel that you can clean up, or slightly overdrive to get a nice tube amp sound. This amp is also all tube and has built in reverb. One of the things that aren't fun when it comes to this amp, is bringing it up stairs. It can also be too loud for apartment complexes so be careful when you crank it.
