While doing the "Moog Slayer" mod on my EX-800, I was surprised to
find a lot of other trimpots in there.  Anyone know what they're for?
 Are other mods possible--a dedicated chorus switch, maybe, or filter
attack and release?

Never mind, just searched the history

What did you search for alternative? Are there other mods to do?

Well, people basically said that the other trimpots are not useful
functions to bring to the front panel.  However, someone mentioned a
mod for creating a dedicated mod for the chorus, and I got to thinking.

I don't like the chorus on this machine--EX-800--and am thinking of
building in a Boss or Yamaha chorus, from a stompbox, and putting
knobs on the face to control it.  I wonder--where's the chorus board?
 Perhaps I could just replace it with the board from, say, a CE-2, and
then when the chorus parameter is set to "1" the signal would be
passed through the Boss board instead of the original one.  And I
could solder in leads to knobs installed near the others.

Forgive me if I'm insulting those of you who like the chorus, but it's
so noisy I can't bear it.  It makes me Juno-60 sound quiet by comparison!

Odd I never had a problem with the chorus being too
noisy. If anything, I wish it was a more pronounced
effect.

If you do choose to mod out the chorus, take some pics and let us know how you did 
it. I am attempting the Moog Slayer mod tomorrow! Wish a non electrical guy luck!

re the "moog slayer"
the key to soldering is patience!
