Why do the fret markers stop at the 17th fret on most semi-hollow and hollow body Gretsch fretboards that have thumbnail or block inlays? But on fretboards with dot inlays, there are markers at frets 19 and 21. I'm just getting into Gretsch so forgive my ignorance. This is about the only thing on my 6609 that I would really want to change. I honestly didn't notice it when buying (online via Sweetwater) but in person, it was more obvious. To me it looks incomplete without the high fret markers, like someone forgot to add them to those last couple of frets that usually have them (on most any other guitar). And why not even side markers at least? Maybe this is some Gretsch tradition (this is my first Gretsch) but I have to say I'm not a big fan of it.
