I have recently acquired a GBIV which has been retro fitted with a Bad Ass II bridge. I have fitted my customary D'Addario Chrome flats and, as a result, I need to tweak the truss rod and/or adjust the bridge saddles to lower my action. The problem is that I was supplied with no allen keys for the adjustment of either and the two I used to adjust my Waraick both seem to be too big. Anyone know: 1. What size allen keys I am likely to need? AND 2. Where am I likely to get them? All help gratefully received as usual.
