Just bought a new Confidence Booster, and have been putting it together like mad for the past two days (my very first time with a PCB and soldering iron!
). After I finished soldering the last wire, I ran it over to my amp and plugged it in. To my dismay, no sound came out. So I hopped on to the forum, and saw I made two mistakes. I soldered the (brown-black-black-orange-brown) resistor in the 4th slot, and the (brown-black-black-red-brown) resistor in the 6th slot. In simpler words, I soldered the 10k into the 100k slot, and the 100k in the 10k slot. My second mistake was wiring stereo for out and mono for in. So I switched those as well. I took it back to amp, and this time I was getting a weird fizzing noise that seemed to be affected by the guitar. Ok, this is a step forward. After messing with it a bit, I found out that if I pressed down on the transistor joints and a few others (marked below), the sound would clean up and sound just great. If it helps, I broke the stock 2N3904, so I had to go buy one at Radioshack. All help is appreciated!
P.S. After I found the "pressing trick", I reflowed the joints, still same thing.
