I use this slide for steel string acoustic guitar, and it performs well in a number of situations. It arrived well packaged and the quality of the item is very nice, smooth brass with well rounded edges and no imperfections.
I have fairly small hands and this fits on my ring and little finger well. I use this slide in a traditional blues and slide guitar way and it produces a lovely sound in both a solo guitar and band setting. I also use this slide in a more experimental way in combination with guitar effects pedals (In the same way as an E-Bow)
