What kind of equipment do you use? Guitars ... pick ups ... amps ...? Do you use different equipment in the studio and when playing live? If so, why?

I have two guitars I use fixed. One is an Epiphone Les Paul and the other is an LTD CC 1000. Both are original. They have a slightly different tone, which gives me more possibilities in terms of sound. The amp I use is the same one I have used for almost 20 years. I have a Marshall JMP 1 preamp, Marshall JFX 1 processor, and a Marshall EL34 50/50 end stage. When playing live, I use Marshall Lead 1960 4x12 cabinets. In the studio I do not use speakers, but take the line signal from JMP..n right in the table.
