Hi Wokkaboy,

Not sure what you are meaning by the F and G type scales?

Yes it's a bolt on neck but the neck heel doesn't have any drill holes(yet, haha).

I will reverse the bridge so the screws face the bottom of the guitar as you suggested but first.

Before measuring do I need to reposition the saddles to the far forward position again like you suggested before, with the high E and low E?
