Hi all, I've been playing guitar since about 1985 and have owned all kinds of gear at one time or another. I've owned several various tube amps and been successful tinkering with their innards.
I now have a Marshall Master Lead Combo Model 5010 dated circa. 1986. It's just like one I used to own in 1989. Lately I have been into reacquiring retro(old) gear I used to have.

This amp was supposed to be the solid state equivalant of a JCM 800. Well, to my ears...maybe.

I want to change some tone stack values around, and my question is if this is supposed to sound like a JCM 800 why is the tone stack so different?

Has anyone around here messed with one of these?

Thanks so much...Mike
