I have some fret buzzing going on on the low e and a string when fretted at the 4th fret. I purchased the fretguru 2 tool that has a "fretrocker". As I suspected, it rocked when spanning frets 4-6 meaning the fifth fret is a tad high. When examining the fret it looks as though it may not be pushed in all the way - from the top of the fretboard it seems as if it is but when looking underneath the strings there is a tiny bit of space that I can't see with the other frets. My question is should I try to just tap it into place or is a fret leveling in order? Thanks!
