I did more research on saddle sanding and how much to sand and bought some sandpaper the next day. After the sanding, the playability improved. To be honest, the high action was still a problem because of the way the guitar was built, but I could at least now make those chord transitions without difficulty.
I still have all three of my guitars with me. Ocassionally I switch between them to play certain songs more suited to each guitar.
But there's no guess which one I play on the most often
.
I guess it's the same with people. I don't claim to be an expert on relationships or guitars, and some guitars may indeed be beyond any hope even after doing many things for them, I have had such people in my life. However, I realised that most of the time, we are too quick to pass judgment on other people and throw in the towel. Perhaps we should attempt to see if some of the issues in our relationships can be fixed, although it may require some effort or pain on our part to do it. We should also decide whether some of the flaws of a relationship can just be accepted or managed if fixing them is too difficult.
And that, is my take.
