Hello
I have a Excalibur Supra and E and B string buzz.
Action is exactly 1.5mm, as per specs and I like to keep this setting. If there was a truss rod I would check this setting.
Is there anything I can do to fix it?
Another thing: even if I got it brand new few months ago it's a model of 2012, therefore it has a single zero fret. Will I be able to change to a 6 pieces zero fret?
Regards

Where does is buzz ? If is is in the higher notes, raise the bridge. If it is on the lower notes, control the neck curve.
Yes you can put a ZerofretS
