Hello Simon,

I have a fixed bridge, although I think I will be receiving an adjustable one from Adam as I emailed him yesterday about the measurements.

As for the measurements, I went and bought an accurate straight edge as I didn’t trust the tape measure I was using. Nut to centre of 12th is 312.5 mm Click image for larger version.

ID:	24119and 12th to bridge is between 314 and 317mm depending on which of the fixed points you use, (see pic) so I reckon it’s close enough for jazz. Obviously the adjustable tail piece will make this even better.
