Just had some stupid questions, your help is appreciated. I owna Marshall JCM900 Dual Reverb head, and plug it into a 1960A cab. Now I have never really bothered to check out the way to set it up properly, and would like to know about the ohm selectors on the back, which input I should be plugging it into on the cab, any sort of info about that would be cool.
Secondly, I am toying with the idea of buying a 2nd head, and wondered if it is possible to run 2 heads through one quad box, or is that just gonna blow the **** out of my celestians?
I know, they're stupid questions, but I just plug in and play at the moment, and want to know a little more about the tech side of my setup.
