Weird noise on DIY pedal...

[Pierre]

Well I built a OLC circuits Thunderchief to take care of my blues tones and everything went fine, but after a while it got weird. I turn it on and it works fine, but after 20 seconds the output drops entirely and I can only coax out fart like noises out of it. It's a JFET emulation. Any idea on what it could be?

I don't think it's a bias issue, since it starts out fine.. maybe a bad solder joint? I know back in the day when I just started modding pedals, a tube screamer was doing the same thing... It turned out it was just a resistor that was poorly soldered.

They're all socketed and the pedal used to work fine for about a week.
