About the Marshall DSL40C amp:

The Marshall DSL40C is a 40W combo released by Marshall in 2012. In 2016 it was the third biggest selling amp (Source: Reverb). It has an intuitive layout with two channels, classic gain and ultra gain with two voicings per channel.

The classic gain channel has clean and crunch and the ultra gain channel has lead 1 and lead 2. So each of the four voices across the two channels makes up the gain spectrum. So you get everything from sparkling clean to massive modern metal gain, all in one amp.


The overall EQ section has the standard Treble, Mid and Bass, Tone Shift, Presence and Resonance. Tone shift scoops the mid. Presence pushes the higher frequencies even higher. Resonance works the same on the low notes and seems to add more low-frequency gain.

Two reverbs, one for each channel completes the front panel. On the rear, there is a switch to cut the power by half by moving from Pentode to Triode mode.

So the purpose of this switch is to allow the amp to break up at lower volume settings. Then there is a foot-switch out and also a send and return for the series loop along with a switch to turn this on or off. In addition, there are also three speaker outputs.
