Thanks Don n Kerry. Yeah, I know that if I press that hard it is bad technique. True Don. You and I do think alike on how we analyze and make conclusions on things. The Stainless frets were in the front of my mind, and I can also see how lots of bending, and vigorous playing is likely to cause flattening and wearing down of softer metal fret tops. I just was really clueless about dents. I can see them forming if one takes the strings and has years of rapid small side to side bending actions which essentially bite into the soft metal to start an erosion.
