Eth that's cool! I'm glad it works for you :-)It sounds different than a cap but in a cool way.

Eth, to be honest with you I was just bored one night and it was getting pretty late. I was also a bit sleepy, which is when the wacky ideas come to me! (ha, ha) Sooo..I said what the heck. I gave it a try. I figured if it sounds terrible then I've only wasted about about 30 seconds of my time. Fortunately it sounded pretty cool. Different diodes give you a different tone and also alter the frequencies differently.

"Besides eliminating feedback and maximizing nonlinearity, which a bypass capacitor does, a Diode would cause no time constant. It does sound different than a capacitor though, definitely-I think."
 
 
True, I can dig that man! :-)

" I haven't tried putting a cap accross the diode or putting one in reverse though. I tend to hear with my eyes a little bit, and I can't think of any effect that it would cause!"
 
 
I've never used the cap in parallel with the diode because it get's a bit too mushy for my tastes but you may like it. You never know  
 
Give it a try!
