bill uses one of those digitech 8 sec. stompboxes in his video, The Guitar Artistry of Bill Frisell. he no longer uses his compressor or vol. pedal. when i saw him a few yrs ago with paul motian he was using a jamman and having kind of a hard time with it. i think he might have just gotten it at that point and wasn't really sure what he was doing with it. =-) PJ
