Karate shop : HUM

[add4]

Hello

I finished a karate shop the other day. Love the effect, hate the HUM that comes with it. It's like 1/10 of the signal volume and very hearable. Is that Normal for that circuit?


Thanks

Might be an open ground. Check your grounding points on your jacks and board and make sure they are all secure and soldered well.

Mine does not hum, so I don't think it's normal.
