Thanks for the reply.

Yes, indeed so. I read some comments elsewhere that the Polysix  
schematics iss full of errors. This could be one of them.

Yes, that is right. Mine is 4.7K though, and that could be because  
Korg discovered that it was "too much" treble boost.

I have them! Thanks for sharing them.
I am going to implement them all, but with front panel switches, so  
that I can switch between the original and the modified versions. The  
bass and the treble mods are on/off functions, but the "bypass the  
post-effect VCF" mod needed some elaborate triple-switch thinking.
