To properly mount a phono cartridge, you need to be able to position it so that it remains tangent to the record grooves at all diameters. This is always a compromise. This gauge helps you to mount the cartridge to the headshell for the best compromise.
The protractor lets an amateur do professional phono cartridge alignment. In just a few simple steps, the Protractor gives precise alignment for better sound and longer stylus life with any standard phono cartridge and radial tonearm.
Made of durable 2mm ABS plastic allowing you to precisely adjust your cartridge/stylus by providing a clear top view. Easy to follow instructions included! Unlike similar market alternatives, our protractor is UV Printed and cured for 3 hours ensuring the highest quality print: so you'll never have to worry about paint peeling off like with comparable products!
