Hudson Hi-FI is an awesome company, easy to work with, fast shipping, and great prices. I purchased Hudson's Hi-Fi Turntable Phonograph LP Phono Cartridge Stylus Alignment Mirrored Protractor (V2) to dial in my vintage turntable and brand new AT150MLX cartridge. I have used many alignment tools over the years, and this one is superb. If you are an audiophile with expensive gear and the desire for perfect stylus tracking and alignment, then just go buy one of these.

How to: First adjust your stylus overhang and make sure that's right.. Then you just fit the protractor over the record spindle, position the tone arm cartridge over the outer most grid on the mirrored protractor. Adjust the cartridge position to make sure the cartridge is adjacent to the grid lines (with the stylus centered in the bullseye), then check with the inner most protractor grid. Keep making minor adjustments until the tonearm/cartridge are as close to perfect as you possibly can. Simple and takes 5 minutes.

This stylus protracter made it easy for me to install a new cartridge in my turntable. I haven't had to change one in decades, and this is an excellent tool!

Probably the best deal ESPECIALLY given the price. I got the bundle for $19.99. I was able to quickly set up the cartridge using both tools. Verified against HiFi Test Records Producer's Cut. Everything matched. Note, that you can get the same exact VTA adjustment tool but for $85 from outlets like Music Direct or Needle Doctor which I found ridiculously overpriced.

Oo nice bold, fat print. Easier on the eyes then other similar protractors.

Excellent product, well made (In USA!), worked perfectly. Very happy with the purchase. Gridlines and center line were detailed, (Not off or crooked) and aligned. Priced great as well. Highly recommend.
