This is exactly why I involve myself in so many tuner discussions. There has been a ton of, we'll call it "varying instruction" on tuners for a long time. We're still reading some of those variances in this thread, to this day. Old habits die hard, I suppose.So when I asked the maker why he quit making thrm he said people won't use them as instructed and I am tired of the people. I get it! Fortunately I bought several back then, still using them.
