Here you go. It's not quite as described since I didn't save that. I've recreated it as an effects combi. Just put your amp'ed guitar (or anything else) into it. I've set up some controls on the combi. But you might get better results just changing the echo times/pitch values etc. I've found just striking a chord and hitting 'lock' produces quite nice sounds (since it's modulating the lock buffer and the feed back is being re-pitched).
Hopefully it should make sense but give me a shout if you have any questions.
I'd be interested in hearing other ideas for using polar.
