It will probably never matter that these things are mostly ineffective, because everyone will remember an instance where one or all of these procedures seemed to help the situation. They won't remember all the times when they didn't work, or perhaps they didn't do it aggressively enough, or in the wrong order. It couldn't be that the information's not gospel because ( output to stone ) that's what their old revered MENTOR taught them to do, so it must be right ( end output, display for eternity). You may even get a number of responses agreeing with you, and might even make a tentative convert or two, but the next time the question of tuning instability rolls around on the wheel again, you'll get the same old responses. My question is, since so many folks are going on what they were taught here, instead of comparing it for validity, over the long run, against their own experience, where did this information originate. We didn't all have the same teacher. Who had the original "original" thought, and why did everyone automatically believe him? Talk about unquestioned credibility! Who the heck was that guy? Ron N
