Re: DSL50 or JCM800
I've always loved the tone of artists who used Marshalls (AC/DC, Page, Hendrix) but I would always be disappointed when I went to try them out at the store (i.e., DSL's) . That is until I got to try a JCM 800 and and then a plexi RI (my current amp). One thing you have to remember though, I don't think you buy these amps for their "clean" sound, so these may be mutually exclusive goals, depending on your style and your definition of clean. The way I like to describe my amp is that it gives me a "clean dirty" sound that is perfect for blues, rock and hard rock. I used to have a Fender Red Knob Twin that would never break up, now that's as clean as it gets and too clean for me.
All that being said, the sound does clean up when you roll back your guitar volume and I've found that your picking attack (or use of fingers) provides a lot of dynamic range. Case in point, my dad, a Chet Atkins guy, played beautifully clean stuff with his fingers and I then proceeded to make the amp scream with an aggressive attack of a barre chord - the settings wre the same.
