It required no tweaking or twiddling to make it work. It is different from other tone rings. I would recommend that you try a J.D. Crowe model to see if you like the way it sounds. I can't answer that. They are both good banjos.
Banjos are individual instruments.
You might hear a particular Scruggs model you like better than a particular J.D. Crowe model. I would recommend that you listen to many instruments before you shell out about 3 kilobucks for any banjo. But I will say this, chances are you will like the J.D. Crowe model, if you like the way J.D. Crowe sounds when he plays the banjo. I'm not through testing this tone ring. I haven't had a chance to put it in a tone bell rim, and I probably won't get around to it for a couple of months.
