The company behind Luminlay just recently released a new product, called the "MAGIK-ARM"
This is something I've been waiting for, literally for years.
RED BISHOP High quality original guitar and bass parts
The video shows it all, it's a trem arm holder replacement with a screw collar that is machined in Japan, and it's machined so well that it doesn't have any play, and unlike a Floyd, you don't have to keep tightening it all the time. When you tighten it, it stays tight. Want it loose and not tight? That's fine too, and it will STAY that way. And it doesn't require a set screw either. It's priced fairly reasonably as well.
Yes, the video shows a Floyd, but they do make one specifically for the edge & lo-pro edge -- it also works with the Edge Pro as well! YAY!
They also make replacement arm holders for Gotoh 510s (and ofc OFRs) as well.
I hope this post isn't taken as spam, I'm not affiliated with them, I just happen to think this is a sick product that someone finally came along and made and solves a HUGE problem that I've had with certain Ibanez trems for a very very long time.
I can finally throw those stupid white bushing things in the trash bin where they belong!
I must've ordered at least 100 of those from Rich over the years lol.
The one downside, however, is that you don't get compatibility with the cooler Ibanez arms like the JS
Ultralite and the Duralumin arm that was made for the SynchroniZR -- at least I don't think this is possible, I haven't tried it though.
