All four of my tables have RB300s on them. The cartridge that it helped with tracking was a Shure Ultra 500. It has done the same thing to an Audio Technica AT150MLX, a Dynavector 20XH,and a Stanton CS100. The AT tracked the best to begin with, but the Groovetracer seemed to clean up the sound. I played drums for about eighteen years, both rock and jazz. I pay a great deal of attention to the way drums sound on records. The Groovetracer makes drums sound much more real. Cymbals sound like they should and they do not have that fake "technicolor" sheen about them. There is a Dixie Dregs album called "What If". I use this album as a tool to find good sound a lot. I have never heard this record sound as good as it does with the Groovetracer installed.
The Kerry F2 is a really good counterweight. I owned one, until I heard this weight. The Groovetracer just sounds better to me. I have a couple of the Regas tweaked in rather odd ways. I had to have additional weight on two of the Groovetracers I bought. This was not an issue to the designer and the effect on the sound was equally satisfying.
I appreciate your questions. Feel free to write and ask anything else that you wish.
