Re: Oiling fret board
I use Fast Fret on my strings, which also has lemon oil in it, I believe. It certainly seems to do a good job at keeping the strings clean and sounding bright, but of course it tends to get on the fretboard as well - so I just slacken the strings a bit to allow me to treat the fretboard all over. Then I clean it off with the cloth provided. It's more to keep the fretboard clean than to "treat" it in any way...
