Korg Poly800/EX800 Users

Hey Poly 800 fans. I did the standard (non-moog slayer) filter cutoff 
and resonance mod to my 800 and am happy with the results, but the 
range of effect of the pots is not ideal. I used pots of the same 
values as the trimmers that the pots replaced (100K for the cutoff and 
10K for the resonance) as advised by this german page ( 
http://www.msc175.de/projekte/poly800/ ). They only seem to have 
effect at the very top end of their movement. Anybody out there have 
better luck with different pot values? Would you mind sharing them 
with me? Thanks!
