Korg Poly800/EX800 Users

I was on this list for a while, but ended up selling my Poly800. 
Now I am back, this time with a EX800, it just has a sound you 
fall in love with and have to come back to..

Anyway. I had mod'd the Poly800 with filter and Q knobs, but the 
EX800 is straight. I am thinking of doing the 'moogkiller' mod, 
has anyone here done this? Does it make a big differnce than 
the 'regular' filt/q mods?

thanks
