Keeley OxBlood

[alexirae]

Hi guys,

For the ones who haven't see it this is the OxBlood:

Some sort of improved Klon.

I was wondering if there is any possibility to:

- Have a readable version of the Keeley OxBlood schematic, I found on his Instragram that the motivation to make the OxBlood is some sort of improved Klon so here are the different schematics prototypes, I think the last image is the "final" version.

- After have this done have a discussion about what are the main differences in comparison to the Klon Centaur

- Make a vero layout for this pedal!


Looking forward to hear form you guys!

Schematic:


What is missing here is to know what model of Transistor and OpAmp to use, any recommendations from experts?

Also other stuff is missing, the 3rd potentiometer (I guess Volume) and the Phat and Clip switches, it would be nice if someone else can extend this circuit knowing where to add the missing parts and the right components for the Trans and OpAmp.
