I know this has probably been answered a hundred times over. Trying to get as much reading done as possible while still appearing to work. I have a late 80's Marshall JCM 900 2x12 combo. Got everything set up and ran the FX100 through the front. Got a great sound and could tell the differences from the multiple set ups. Like others, I still have that clean/crisp Marshall sound. May not be able to get there from here but I want to get a heavy crunch. Playing a Jackson Dinky. Have an old BC Rich that has been set up drop tuned but have not tried that one yet. Any help is greatly appreciated.
