Arsenio Novo's v.2: distortion + octave up + booster

[mac]

A new version which is more similar to Arsenio's original drawing.
I used a pair of matched NPN PNP silicons.
This version now has distortion, octave up and booster by simple changing the base bias.

Thanks Arsenio... wherever you are!

Interesting, thanks

El control de Drive es tambien "Crackle okey"?

Saludos!

Hey, pedis mucho!!!

I forgot to say that drive should be lowered when on octave mode.

Who says there is nothing original out there? Looks like a very odd Bazz Fuss variant, but very cool. I wonder if other NPN/PNP pairs would work, like 2n3904/3906 or 2n5088/5087? Thanks.

IIRC this design dates from 95 - 96. And it is like a Bazz Fuss. Or the BF like this...
I recently posted a circuit, a mixture between this and the BF,

The tuning condition for distortion is that the PNP base current is zero, so its base-emiter path is just like the BF diode. IIRC, one could replace the PNP with a diode with bias adjustment.
