The strating point was this schemo. http://www.diyguitarist.com/Images/ICL8 ... ematic.gif
This is where I am now.
Here is a direct url to the schemo, it was too big to fit to the page.http://www.fileden.com/files/2007/11/17 ... 0mods2.GIF
I dug up the info for the modifications to my starting point here. http://www.datasheetarchive.com/pdf/1697144.pdf
I can test this on breadboard in next week because I,m on a holiday visiting my folks.
could someone check this for things that won't work. And feel free to comment. And if you are interrested enough to breadboard this, please tell me if it works and if it doesn't work we could brainstorm it to work.
My goals on this thing was to have adjustable output level, variable frequency and simple desing.
