HI,

I wish I had time to figure out the AD999, I hope one of you will. You will find out there is something tricky in there - it does not work like any other analog delay I have tried. It sounds different at low and high delay time settings. But not quite like the MXR analog delay trick. It almost sounds digital at low delay times. Certainly not as good sounding as the AD-900 at long delay times.
DIY has unpleasant realities, such as that an operating soldering iron has two ends differing markedly in the degree of comfort with which they can be grasped. - J. Smith

I'm impressed - twenty four trimpots??

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

Yup.  Kinda makes sorting through a pile of 20 Ge transistors to find a pair with the right hfe for a "boo-teek" Fuzz Face look like child's play, doesn't it?  Correct me if I'm wrong, but those green things distributed all over the board ARE contacts for test points in order to accomplish those trim pot settings, right?  The board legend says CP1, CP2, etc., beside them.  I'm more accustomed to seeing the nomenclature of TP1, TP2, etc for "test-point", but that can't be for "capacitor" because the caps all say C1, C2, etc.

I'm not sure what's the bigger cost in the manufacture of these pedals, the parts, the assembly or the setting up.
