Anyone have any scope camera shots of a Fuzz Face in action?

I have been running some spice simulations of the FuzzFace circuit, (checking for variations in output harmonics) and the output waveform is beyond distorted.  The out put is really crazy looking.  I have not actually built one to check with my oscilloscope.

I was wondering if anyone has any scope pics or any links to some.  

A google search turned up nothing useful.  :?

Cut it large, and smash it into place with a hammer.

Very clever construction. I like how the ground wire anchors  the  terminal strips.

As I suspected, there must be something wrong with the spice model.  I have already lowered the Beta of the transistors to a value near the "magic mojo" level.

I have to review the model to see what the problem is.

Those are not actually photos but screen captures of a software scope using the sound card. Must be close enough.

There are captures of properly biased (=magic mojo) and bad biased, so you can compare.

Which spice model did you use for a Ge transistor?
