Hi, I'm new here to the forums, and am proud to be here. Just wondering what the general opinion is of the DSL 100H. I just got mine and since my wife is home from work today I couldn't really try out the bad boy yet. Got it at Musicians Friend and reading one of the reviews, it was said a mod was in order. Here is the quote from the review "Comments about Marshall DSL100H 100W All-Tube Guitar Amp Head: The secret to great tone with this amp is to remove C19, which is the first thing I did as soon as I got it out of the box. I already knew I had to do this mod. Once done the tone warms up, and since both channels share EQ, you don't have to go and adjust every time you switch channels. I don't understand why Marshall added C19 that makes the OD channel sound fizzy and thin, but after the mod it can go into JCM 800 territory." What is "C19"? I asked the tech guys at Musicians Friend and was told that it was an internal mod that would void the warranty for sure and in any case was not necessary. No clue what there talking about with "C19" Honestly, a dumb ass "like me" would be clueless as to the results I was to get from this mod, and feel like its something for you guys that do have a clue. Is there anything to this? And did I get a good amp?
