This improvisation was made using a JamMan and a Boss DD3 foot pedal digital delay, and was specially played for this web-site. There are no overdubs, just my voice and delays. I have tried to show a range of what they can do in order to keep the audio example short, but in a concert I would allow things to unfold more gradually. More recently I now use 3 Boss pedals - DD3 (digital delay), PS2 (pitch-shifter) and looper.
