If you are looking for a modern version of Audio Technica's AT6002 known as the Autocleanica or similar, this is Tonar's modern quality all metal solution. Well, except for the carbon brush!
Cleans records as you play - reduces record and stylus wear by keeping those grooves dusted while you play - Eliminates static build-up. Will not interfere with tracking force and anti-skate like the brush that attaches directly to your tonearm. This is because it mounts on the left side of your deck and so does not interfere with any tonearm operations.
