eBay item #7390654562 is a Chordorama, a big, beautiful, blue-glitter finished pedal that was a bit like the mid '70s equivalent of Ableton Live. Insert a specially-made 8-track tape of you backing track, and each of the footpedals triggers a different instrument: "The first eight buttons play the individual tracks and the ninth button to the right played all eight tracks at once. For example the tapes may be recorded as such: Track one is usually the drum loop. Track two is the drum loop and adds a bass line. Tracks three and four all add a chord here and there or incidental percussion." A few hours to go, and it's just $46... (Thanks, Jaimie)
