Diodes? For the ZVEX Machine? Or dual crossover distortion diodes?

[jimbob]

Does anyone have any idea what type diodes are used in the ZVEX Machine? Are they 1n914 type or Germanium? Or better yet, what would be the ideal diodes for a dual crossover distortion?

Try 'em both, or even something else and see (er, hear) what you like best.

Come on, be daring! Throw caution to the wind and experiment!

Germanium. 1N34A is ok. 1N260 is probably fine too.

I used germanium in my build and it worked out fine.

In Tim Escobedo's Tripple Fuzz, upon which the Machine is very likely based, he uses Si clipping diodes.  I have tweaked Tim's designs every time I build them, and I can never improve them.  So I'd imagine Si works well.

That said, the Machine is basically two Tripple Fuzzes in line, so maybe Ge diodes at the end make the pedal slightly less fuzzy.  Maybe the fuzz was too much with the Si diodes.

BTW, the SHO section diodes are certainly Si.

Use 1N34A.

I used 1n914 but just for the hell of it I might try the 1n34a. Or-m use a spdt to switch betwen the two assuming it makes any audible difference. Great effect when used with another effect such as a fuzz face.

ok- per Mr Vex himself on his website I found this:

a pair of back-to-back germanium diodes to the output in order to fuzz out the taller direct guitar waves and make them about the same size as the crossover distortion triangles.

So for those who thought it was germanium-YOU WERE CORRECT.

I'm gonna make one myself soon.
