Title: Stutr Hiss
Post by: Droogie on April 05, 2016, 06:57:16 PM
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.

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 :()!
