Title is a bunch of keywords, sorry. I got a Tagima TW61 that I love, but I decided to try flatwounds a while ago. While I'm loving these(D'addario Chromes at 0.10), my G string is now a sitar... Yes, it's wound in this set but the nut seems fine. My research has said that since it's on all frets, it's not on the nut but on the bridge saddle. Cool, so now I need a proper tool, and a way to do the work withouth losing the strings(they're kinda hard to find and expensive here , the plan was to worry less about strings for a while)... Or find a tech, but my experiences haven't been very good. What can I do? For now I am trying to be less heavy handed, it helps, and is a good habit I guess... But I'd rather have that be from free will, instead of from a tech problem!
