VPI JMW Jig Question


The JMW jig I got with my Classic arm has an adjustable length. How do I know if my jig is set to the proper length? You would think that VPI would make a scale on the jig for their various 10 to 10 1/2 inch arms.

Yes, second to the Mint LP protractor. Much more precise and accurate on my VPI SSM, makes audible improvement.
