Mini Heterodyne

[sndansby]

Hi,

I just finished the mini build and I was able to get it working, no minor feet for me. I just plugged it into my amp and I am getting a high piercing tone coming through even when the pedal is not activated. The tone increases in volume when you turn up the Oscillator. Does anyone have ideas on what may be causing this?

Thanks

Tough to say, most likely a short somewhere. Can you post pictures of both sides of the board?
