The Dunlop Joe Perry 257 Signature Boneyard Slide sounds bluesy and soulful whether you're jamming on an acoustic at home or rocking a shrieking electric in a packed arena. Aerosmith's Joe Perry is a guitar legend, and his material of choice for slides is porcelain. Joe likes the way the rougher interior surface absorbs moisture and keeps the slide on his finger.

Additional Slide Information


  • Between glass and brass for weight and tone
  • Glazed exterior - different glazes can create slightly brighter or darker tones
  • Porous interior absorbs perspiration and keeps slide in place


Slides typically are sized S, M, L, and XL, which refers to the inside diameter, specifically.

  • Small — Ring size 4–7.5
  • Medium — Ring size 8–10.5
  • Large — Ring size 11–13.5
  • Extra Large — Ring size 14–16

These are approximate — slides vary from model to model and are handmade. The basic process is to figure out which finger you want to use, get a ring size, figure out what material/type of slide you want, and get close. It doesn’t need to fit like a ring. A little space is a good thing: snug enough to stay in place and have control but loose enough to be comfortable


Shorter slides are useful if you want to wear a slide and switch back and forth between fretting and sliding. A shorter slide allows your finger to bend and tuck out of the way.

Longer slides can cover across the entire neck (all six strings) allowing more immediate note choices and possibilities.
