I've just made a new pedal!

Based on the basic booster, but modified. It uses a darlington insteag of a bog standard tranny, and has clipping diodes; in my case two vintage TFK germanium diodes from the 50s.

It goes between light overdrive, and heavey (clipped!) metal. the darlington gives much more gain, and I've used a 20k pot instead.

Anyone want the schem?

Sure, can you post it?

What is a good program to draw schems with?

(preferably free!)

Express PCB comes with a schem program for free. Peter Snowberg turned me onto it. It is a pretty good program and fairly easy to use.

i have circuit maker 6, student edition.  takes some getting used to, but decent, I think...haven't used anything else, though.

:mrgreen: I use MS paint. Works great! :mrgreen:

seems like one could [with a Digital cam] draw a nice sharp feltip picture, and take a picture of it.

Give this a shot, its what I use. It has PSpice 9.1, so you can do circuit simulations, which is pretty cool, it takes some learning to do things other than just drawing circuits, which is straight forward.

After you get that, you may want to check out this thread about PSpice libraries for orcad:

You can IM me if you want the full PSpice libraries, or you may be in luck with that download (it might have everything already).
