just curious how you guys treat your Rosewood fretboards. for the longest time I was using Kyser len oil and was told from the gate never to let oil rest on the fretboard but rather wipe it on and off. doing this a lot of the times the fretboard looks great for a day or so and then looks drier than a bone like it has some kind of wax on the surface. recently I conducted an experiment on an SG where I let the oil soak for about 10 minutes on a very dry fretboard when I wiped it dry it darkened by about three shades which has still held up for about a week and there has been no noticeable changes in the playability of the guitar. as of now I’m gonna have to say I am in favor of oiling boards when needed and I’m wondering why so many people seem to be afraid of fretboard conditioners? let me know about your experiences! thanks!
