What Did I Do To Cause This?

I just finished my first build, and when plugged in to my very old practice amp, I get sound from all three pickups. If I plug the guitar into a difference amp, then I get nothing. I have tested the other amp with other guitars, it is working fine. I have switched guitar cables, plugged in the just finished guitar, same thing, beat up old amp... sound - nice new amp...silence . I have a mono jack, and as I said sound in one amp, but not the other, but only with this one guitar. What in the world could cause this?

what sortof pickups do you have in the guitar ?

actives ? any active electronics at all ?

Using a stereo cable?

It is a mono cable, Bill Lawrence Pickups. Last night while working on the electronics, I noticed that a few strands of the ground to the jack were touching the plug, I cleaned that up, and most of the noise in the amp that works disappeared, and the signal improved dramatically. I did not have a chance to try the other amp, and the little man who moved into the house decided to throw a fit ( as only 3 year old do ) and I will have to wait to get to this again. Could the loose strands have bleed off enough signal to prevent the one amp from working?

I'm not an electronics guru, but I think it may have been able to. Electricity will follow the path of least resistance and a direct path from wire to cable plug has less reisistance than through a solder joint.

Nope that did not solve the problem, so I am back to square one. I think I will rewire the whole thing.
