Ah, you see Dan, if you used a self-resonant design (just kidding, it would 
not be easy to make a feedback based audio SSTC) , then many things are 
possible, including the jaccob ladders ive built with my SSTCs.

For some cool experiments see this:

also, other experiments in the SSTC index:

have fun!
