The AXYS slide works best if it fits snugly on your finger, just like a ring. That way, the Delrin "ring" section will stay put when you rotate the bronze "sleeve" section.

We suggest using your RING FINGER.

Many slide players have designated their pinky as the slide finger, probably because with the traditional tubular slides or bottlenecks this was the best way to gain some limited use of the other fingers for fretting. Since the AXYS offers such unrestricted use of all the fingers, we encourage you to consider reassigning the slide to the ring finger or even the middle finger. Most players find this to provide greater control and versatility. It will work just fine on your pinky, of course, but this is a whole new ballgame now and you don't want to overlook any good possibilities!
