So I got my SX jazz 5r a few days before christmas and I gotta say I was really impressed. The action was actually not bad. But alas I can tell the frets do need a bit of work and I was fiddling with the idea about dressing them myself. Now im a fairly handy guy, I do all the tech work myself thus far BUT I gotta say there is one thing about the dressing I dont quite understand and totally sucks out my confidence (which is a big deal for me when doing a project). So here it goes, I can understand using a flat file on radiused frets but why would I be going up and down the fret board instead of side to side? Wouldnt this take the radius off? Or atleast present itself more difficult than a side to side motion?
