Thanks fender3x. It makes sounds but has not had a proper setup yet. I have not tested the grounding of the strings (I know I had to work a while to ground the strings on the MBM-1 build).

I'm liking the Grovers as well, so much so that I'm going back through my collection and upgrading them on my favorite builds! The only issue is that the 406 series locking tuners are the only ones that have the matching screw position!
