Actually I did build an axis fuzz, and it works exactly like I expected, I just couldn't come up with a title that sounded tempting enough to attract people to this phenomenon I ran across while playing with the perfboard while it was out of the box.

If I touch the ground terminal of the volume pot with one finger of one hand, then touch the tip of the output jack with another finger on the same hand,  I get a strange squealing sound that would be kind of cool to open some sort of hardcore show with because its kindof creepy.  It doesn't sound all that bad, until I press my finger completely making contact with the tip of the jack, where the squealing still happens, but I hear some sort of noise that reminds me of putting a probe into a nest of networking wires when trying to weed out ac mains noise out of coaxial tv cables.  It sounds very digital, and I have a hunch that it has to do something with the transistors and their clipping.  If someone could explain to me why this is happening, that would be nice, maybe R.G. because of your almighty knowledge of this sort of thing.
:lol:
Its not a big deal seeing as how I wont be casing a human hand into the enclosure, and don't have to worry about this happening in a practical situation, but maybe I've stumbled upon something useful, and want to know if its just some sort of creepy eerie sounding noise, or something useful.  
Thanks,

Now, don't you start that again!

You're a human resistor!  when you press on something with your hand and something with your other hand, you're making a high value resistance between the two points you're touching.  The resistance gets lower if you press hard, or have sweaty hands.  You could even measure your hand to hand resistance if you have a multimeter.  If one is measuring high resistances in other stuff, and you have your hands on both probe ends, it can throw the measurement off.

Didn't they make old coin-op games with metal posts that you hold with each hand that tell you your love quotient.  The love-o-meter.  It really just tells you how sweaty you are.  :oops:

Jimi must have figured that same thing out (or his tech).  I also ran across it and decided that was the effect he used to record EXP off the Axis album.
