Boingy Slide

by Mark Henderson -
I was messing around with my acoustic when I came up with this one. If you have a slide (glass with rounded edges works best) you can use this effect. Bow the string with the slide on a fret. Press down so that the fret and the slide are touching, then lightly vibrate the note. The result is a boingy wah-type of sound. It also works with an electric guitar, but the effect isn't as prominent.
