I have a DSL20C that I bought second hand , I only play at bedroom level and can only really have the volume on about 1-2
This isn't an issue on the gain channel but on the "clean" channel I am hardly getting any dirt at all , despite playing with a Les Paul with 57 Special plus
Is this because of the lack of volume or is it likely to be an issue with the valves?
Not really , in the end I contacted Marshall and they said the classic gain channel wouldn't produce much gain , which goes against all the evidence I've seen on YouTube but thought it may be the fact that I am playing it at too low a volume to dirty up .
I have bought an attenuator so that I can crank the amp up and keep the volume down so will report back once I try it.
I would suggest you need to contact Marshall direct
Thanks Mark, appreciate the info.
