I keep getting my 7th and 9th frets mixed up. I'm thinking about putting a little fluorescent sticker on the 9th fret to help my navigation. The black dots on the neck aren't helping me navigate. In fact, I think they might even confuse me at times. I know I should probably have it down to feel, but I don't . Is the sticker solution a bad idea? Anybody else resort to that kind of cheese? Did it help or hinder?
