Tuning Lug Bumpers, Vinyl

[Mike]

You are right,
and I have just
equipped my Gon Bops with
this kind of bumpers (took me 40 minutes).

I guess if a guy thought ahead these could be flipped upside down (one end not cut through) and installed with the lugs. then when you want to tune, simply slide them up and crank away...
