Thanks guys and for the time spent listening.
Yes McCreed...like I stated in post #37 I think the bridge could move south about a mm ( or 2).
Always seems to be 'just that bit out' whenever I attempt this.
I also should have made a pick-guard out of MDF like previous and then narrow down the adjustments for acrylic.
cheers, Mark.
P.S. a more 'tremolo' friendly tune would also be a better choice.
