<br><font size=2><tt>"You should try UA776 if you find some ... Not
they sound better , but you will get a better control range and less artefacts
at extreme <br>
frequencies/Q settings. Anyway i am happy you enjoy the sound of this unique
filter :), that the resonnance control would be better using UA776."</tt></font>
<br>
<br><font size=2><tt>and yes, i agree with jeff, it sounds wonderful. i
like it very much and it has a lot of character.</tt></font>

<br><font size=2><tt>I used the LM4250 instead (actually, the NJM brand,
Mouser part number <br>
513-NJM4250D). Only 34 cents each! But don't forget to change R10 and R11
to <br>
1.2meg or more.<br>
<br>
This is a woderfully filthy filter, BTW. I've got 2 of them in my modular
<br>
(http://www.guitarfool.com/synthesizer.html).<br>
<br>
Hope this helps,<br>
