Stringreen,
Here's a link . It's actually a clever tweak for JMW arms that provides repeatable fine tuning of both VTF and azimuth, without moving the main counterweight. It's like the (dirt cheap) O-rings I recommmend for arms without fine VTF, but it adds a scale for repeatability and provides azimuth control too. Looks pretty nifty to me.
If a user didn't hear or care about fine VTF and azimuth adjustments then this wouldn't be worthwhile, but JMW owners who do hear such differences might think it a bargain. What's $62 to enhance the performance and ease-of-use of a $2,000+ rig? Just 3%. Hard to imagine a more economical upgrade.
