Hello everybody, I am new to the forum as I have just purchased a second hand PRS se Fredrik Åkesson and have a couple of question's, first can you use lemon oil to clean an ebony fretboard, I know you can use it on a rosewood one but not maple, and secondly can I expect to get a very low action on this guitar, this is the first one I have owned with a set neck once and finally is there any upgrades worth doing to improve a great guitar further. many thanks Ades
