For the entire time I've had my beat up Yamaha, the electronics have always been a problem. Its a 9 volt active EMG situation, but the problem is actually the jack- it cuts out. I took out the jack (which was jammed, so I destroyed it on the way out) With the intention of replacing it, but I soon realized that the only spare jack I had was a stereo one. I figured I could probably use it as a mono anyway, so after trial and error I found the right contacts to solder. The strange part is, I have to ground one of the contacts to the sleave of the jack, and I can only do this when it is going through my finger. If I solder a wire attaching it to the sleave, no dice. I figure it needs some resistance or something, which is why it works through my finger, but why should this happen in the first place? Does it have to do with the fact that the jack is stereo and cannot be used as mono? The other odd thing was that I pulled a jack out of guitar and hooked it up and it didn't work. Somebody help me!
