Hey guys im kinda new but, what do all 4 of the knobs on the les paul guitar do?
i have a Epiphone Les Paul 100 series

i know that one of them control volume when its only on treble and the other controls volume when its only on rhythm, but the 2 next to them, what are they for? and when can i use them(as in when im on treble rhythm or both)
the back two knobs are tone, the front two are for volume, each for their respected pick up.
