well all the more reason to further investigate this. the Juno uses  
DCOs, but the GR-300 uses some kind of bizarre fuzz-to-trigger-to- 
relaxation core which is then clipped to maintain consistent  
amplitude, as discussed here, and which until 2 minutes ago i had  
never read:

which is just too freaky. it's also exactly the opposite of what i  
remember hearing, which says more about my poor memory than the  
explanatory skills of the very respectable Mr Bissell.

yeah actually i _am_ going to do this tomorrow. under a new thread  
title, i promise.
