Alex's Octave-Up Rabbit Hole

[Ale_jellybelly]

I kept potentiometers for both sides of the common "nulling" mod. Having both of these pots external is definitely overkill. If I redid the boards/schem I'd still keep one external, and have the other either be a set resistor value like in traditional null mods, or keep the other as an internal trimpot.

if I was to add a Null pot to my green ringer build, following the schematic you posted, I'd wire it like this right?:
lug 1: r7
middle lug: Q2 emitter
lug3: c3

noob question but just getting started into modding some circuits and reading schematics

Yup exactly! Doing this Lug 1 and Lug 2 will be connected together as well which might be an easier way to think about it as you wire it up to the board. No bad questions either, we're all learners here

Thanks!
If I can use your help, I populated a board from PCBGuitarmania (I know, I'm sorry, the kit was cheaper...) and I'm having a hard time figuring out where I should wire the pot
This is the board



And this is the schematic:



Which side of R6 and R3 should I connect?
Q2 is a 2n3906 so I guess the left lug is the one to wire to the pot (EBC pinout)

I think I got it:

I'll try it in the next few days and report back

How would you compare Tim Escobedo's Octup Blender to Anderton's Green Ringer? I absolutely love my Shinei Superfuzz clone and want to build an octave-up pedal to recreate different flavors of it with my other drives. I'm also intrigued by the blend feature and the seemingly more robust octave, but I'm not sure if it can sound evil enough to compete with the SF.

Any input would be appreciated!
