Title: General reference on troubleshooting noise
Post by: taeagan on March 11, 2017, 11:52:19 PM
I'm wondering if anyone is aware of a good overall reference or troubleshooting guide for noise issues.  I have a whole bunch of homemade DIY pedals - some madbean, some vero stuff from tagboardeffects, some Anderton EPFM projects... A handful of them have noise problems - some only when the circuit is engaged, some even when it is bypassed, some sound like hum, some sound like some kind of interference (not radio, but like a scratchy pot keeps getting turned intermittently).

I was just curious if anyone knew of a good resource for best practices and general rules of thumb for troubleshooting noise issues.  Thanks.

Power supply, try a battery too, and then an audio probe to see where the noise is introduced.

Wiring, proximity of input to output wires. Proximity of LFO and clock signals to input wiring and circuitry.
