Hello lovely people! I just build my first (functioning) kit pedal, and I am over the moon. I can see how it can be addictive despite the frustrations involved (or perhaps because of them?). However, I am having an issue with a weird noise I haven't come across in a pedal before. It's an EP Booster type. It works 'just fine' (and sounds amazing), but when it's on it's making a low, warbly humming noise which stays constant regardless of the level of boost. It actually took me a while to notice. My intention is to start over with re-soldering etc... but I thought I'd ask here assuming the noise is more familiar to you and you could perhaps point me to the most likely suspect. See video for noise: THANK YOU!! PS There seems to be a slight grounding issue as well. There is a slight hiss which goes when I touch the pedal (I'll re-check the grounding connections). But the video noise I am talking about is qualitatively different.
