Stutr Hiss

[Droogie]

I just built the Stutr from the G boards projects and it works as expected except for a fairly pronounced hiss/white noise that follows the volume peaks. Anyone else experience this?

Definitely no hiss in the reference build. I would first eliminate your power supply as a noise source. Then I would check the pin7 and pin1 IC1 output to see where the hiss starts. Could be the IC itself or your photocell, I suppose.

Thanks! Will do!

Solved! It was just boosting some noise further down the chain from my testing rig at the front. Sounds great—as do all the others (except Sawse cuz no opto )!
