I saw Jaco live at this time (but with Weather Report) and if memory serves, he was using an ADA digital delay. It could also have been an Effectron 1024 as well. What year was this, by the way? It was the first time I had ever seen someone use a delay live with infinite hold and in a very rhythmic way. He looped harmonics with a compressor so that the harmonics and false harmonics were all really loud (never saw anyone do that before either) ...................he had an on/off pedal on one side of the stage when I saw him and at the end of his very flamboyant solo he ran fast across the entire stage and the slid across the stage like he was stealing home into his on off pedal turning of the loop simultaneously. It was so theatrical and punk. I was in awe. I thought I had seen god at that point. I had already experimented with infinite cassette loops and removing erase heads in tape delays (thanks to the inspiration of Michael Haumesser who was the first person I ever saw loop) but you could not control rhythm at all in with those methods or if you could it was very clumsy. Jaco was the first digital looper I ever saw and as a percussionist/drummer the future was clear to see. It would be all the way until Lexicon finally put out the Jamman that I was ever able to manifest my desire to be able to build up rhythm parts and that I think was in '95.
