On the understring felt between the agraffe and the tuning pin, the drag is such that you can often move the pin a LONG way before you hear, or see on an ETD, that the pitch in the speaking length has changed. The problem is that you can't tell where the heck you actually are, which makes it pretty tough to decide where to leave it. If you can minimize the friction between the agraffe and tuning pin, you have a better chance. Ron N
