Built the Egodriver, and its squealing and feeding back like crazy. My soldering iron was too hot so it took off the pos pad of C10 and also the led. I removed C10 and soldered wires to the top side of the board for the led. Lights up, gets bypass, OD works but theres an overpowering squealing and chaos going on. It can be controlled by the gain pot. Could be a cool noise device but I really wanted an OD. Any suggestions? I remember I asked about C10 previously, I think it was fine to leave off. Is my gain pot broke maybe? Anything I should try?
