490. Tweaks? Hacks? Mods?

2003-08-05 by Aaron Day

Hello all-

I just finished my 490. A fun kit to build and a really cool sounding 
filter.

But the resonance thing has got me going---mine flips at about "3.5"

I have read the archives about replacement resistors but was wondering 
if there was a consensus reached about particular values and their 
behaviors. I thought I'd ask before I put another in.

Also, has anybody hacked this unit? I don't need 3 inputs and was 
wondering if anybody had added any features--an amp on the input 
etc--and slapped another pot where one of the inputs should be.

Were there any mods done by the factory of the 904a when it was in 
production?

Best,

ad
