I like that the protractors are made to manufacturers specs. of different turntables and arms. Having an arc along with grid allows for fine adjustments of cartridges. Very Happy with results when using it. The graphics are etched into acrylic, so they won't wear off but would like to see them a little brighter to see them better. Using a light helps. Definitely the only protractor I will ever need and use on my turntable. Shipping to USA was super quick! Very Happy with purchase!
I’ve used tonearm specific arc protectors for setup in the past and find this method so much easier than just the two points variety. This product is very high quality and I expect it will outlive the tonearm. Thank Vinyl Source.
using this protractor is very easy - much better than a paper one. very accurate and the system sounds much better!
It brings my Thoerns to life!
