[sdiy] Student successfully hacked flanger pedal

All I'm saying is that you can "linearize" it with feedback, if it is 
log. My guess is that Buchla wouldn't have added a breakpoint in his 
control circuit if it had an inherently exponential response. However, I 
don't think Vactrols are particularly linear either.
