Sea Urchin volume

[muddyfox]

Hey peeps!

How would I go about adding a volume pot on a Sea Urchin?
The way I see it (astigmatism and all), if I just add a pot at the output, I'd only be able to make it quieter. If it's already too quiet, what are my options for increasing the volume range?
Would it be better to somehow increase the circuit gain with a trimmer somewhere in there or perhaps add a booster at the output?

Thanks!

Easy enough to do. Increase R5 to 47k and put the volume pot right at the output. This will give you unity plus more.

Thanks Brian!

So I'm guessing (and I really shouldn't be needing to guess certain things by now  ) that would be lug 3 to pcb out, lug 2 output, lug 1 ground to get the "normal" CCW-quieter CW-louder?

That's correct. 100kA should be fine.
