Well, here I am replying to my own post ;-)
After I finished at Rockfield (I play a "single" from 7 to 9:30, and then
play one of the bands breaks around 10:30), I went next door and sat in
with the band there. I just plugged my JT-30 into their PA. In the
middle of a particularly loud tune, I flashed on the "feedback"
discussion, and covered the face of the JT-30. When I put it in front of
the woofer, it did make a musical tone that I was able to control by
slightly altering hand position. As I was in the middle of a smoking harp
solo, it went over quite well. (I do crazy things when performing live,
like lay on the floor, etc. After all, this is the "entertainment" biz
I don't think I can use it when playing solo, but it looks like it has a
lot of promise with bands.
