Thanks, I like the spring tip. Had not heard of that one before.
I too twang, and have a few ways of fixing my twang bars where I want them.
If threaded, I sometimes use an aircraft nut, with the teflon inside the head, works on some.
On my old Mosrite, I'm afraid of hurting it, so I use the tiny rubber bands that some use on pigtails, etc. I keep a few extra cueued up, in case one breaks, I just slide the next one up. No mods, cheap, works good.
On my xtSA, there is also a set screw.
