ok, so i have my Marshall half stack, its a jcm2000 DSL head and i have the 1960 B or A cab, (not sure) But anyways, it sounds pretty good on lead 2 but whenever I turn it up to 3 volume or higher, the sounds gets more muffled and sounds like its not as clear and crisp. It seems to have less high end also, kinda like the presence is lowered. Why is this?

Marshall's can be a beast that's hard to tame, but once it's there, you can't beat 'em.

I'm not that familiar with that particular model, I play a JCM 800 and JCM 900, but I'd suggest tweaking the EQ while you have it cranked up. The EQ settings can make a difference at different volumes, especially on a Marshall. In other words, if you have it sounding great at say 3, then crank it up to 8 or 9 (the "sweet" spot on Marshall's), you'll probably have to adjust the EQ to compensate for the added tone from pushing the tubes harder. At least that's how it is with my Marshalls....

I believe the reason Marshall's are more succeptable(sp?) to this, is because they are voiced with a very prominant midrange, and the F-M curve show's that the louder you go, the more the mids are audible. Thus, making it sound like your highs and low's are quieter.
