Re: Lo-TRS 7 Studs - More Durable Alternatives?
Solved my own problem today.
The closest fit for the LO-TRS stud posts that won't get sliced by the tremolo knife edges are Gotoh/Wilkinson VS100N stud posts. I initially thought I'd get less tremolo travel with the narrower v-cut on the posts, but it turned out not to be the case.
I put them on and the trem worked better than before - better return to pitch (no cut posts for the knife edges to catch on) and "flutter" is stronger than ever.
The VS100N studs, like all Gotoh trems, have the locking grub screws, but since my 7420's anchors don't seem to have metal bases, they won't really work well. I just decided to screw them upwards as far as they will go to prevent any rattling, although the screws are incredibly snug even without the additional locking mechanism.
Hope this helps somewhat. Cheers everyone.
