Hello, I have some questions about a 335-style nut. This is a new guitar and I noticed this when changing the strings. Grote 335, I also have the Grote 'Jazz' guitar, and its nut looks very similar. So I wonder if that's how all Grotes tend to be? The grooves for the strings seem to flare outward a little bit on each side. And on the larger strings in particular there is a bit of an overhang. I've never seen this before, is this typical for a 335? My intuition is that this is plum wrong. Now once you get the guitar in tune, it tends to stay in tune pretty well. Pick it up the next day, only a minor tweak needed. Jam session, no problems. It is a little hard to fret the lower frets on the bass strings, for example an F barre chord. Also, the intonation is a touch sharp on the lower frets. While from 5th-ish on up to the devil's playground I can get it spot on. This leads me to believe that the nut may be a touch high. So would I be correct in surmising a replacement nut is in order? If so, I will have some follow up questions as I've never done that before. As an interim solution, I was thinking to use some sandpaper/microfinishing paper and smooth down the overhangs. Is that a reasonable approach? I have two variety packs ranging from 220 up to 14000. What grits should I use?
