Hi,
I inserted some pictures of feedback mod to picture section. On one 
end of potemtiometer corus sounds normally. With turning to other end 
chorus become more enhanced, and between half-way and second end 
sound is the most "enhanced". But unfortunately undesired noise too. 
Next turning will "shut down" chorus at all.  <:O
I added mp3 into the Files section as well. 

Here is description of pot action:
0:00-0:22 chorus off
0:22s chorus on
aroun 0:40s  - turning pot to more feedback
46s - maximal feedback with FM-like distortion
58s-1:02 Pot in "max" position, but without chorus
1:02- turning pot back
1:32-1:45 - one tone , turning pot from min to max
, then some accord an playing with pot..

It is next "noisy" modification, so after all poly800 will be 
surprisly suitable for industrial music ))
