TwoTeiscos

High , I'm a 72 year old newby with an odd problem. I have two Teisco Audition 7002 I am rebuilding.
While checking out the electrics on the first guitar I found that the neck pickup was ok but the bridge pickup
was dead.Switches are working ok.
When I came to the second one it was the same.Am I missing something or do these guitars have a problem with bridge pickups ?
Cheers, Ken.

Pickups

Another question. Are the pickups on neck and bridge the same as I,m thinking of using the two working pickups on the same guitar.
Any comments on this and the above would be very welcome.
Cheers, Ken,

Hi Ken:
There are a variety of vids showing how to test pickups, and electronics, on a guitar.
Watch a few of them and determine if you have the tools, and can do it.

Watch some, then go from there.

I think one of the difficulties with many of the budget Japanese models, like your Teiscos, was that they weren't necessarily planned out to last decades for a working musician. They were, after all, the sort of instrument that would show up in department stores, "for the kids". If you take the pickups apart, it is not uncommon to find that any adhesive materials inside (e.g., tape) has pretty well decomposed, and that the coil is torn somewhere near the outside as a result of tape pulling this way and something else pulling that way.

They ARE reparable, but there will be some frustration along the way, partly resulting from trying to rehabilitate the unit amidst the goop that has emerged from the decomposing tape. The other part will be resoldering the tail end of the coil to a lead wire. Feasible but tough on the nerves.

A traditional trick for isolating the outside free end of a torn, but otherwise okay, coil is to use a pencil with a soft eraser tip, and drag it along the outside of the coil. This will pick up any stray ends without having so much force that it tears the coil in other places.

Hi, thanks for your reply. Just been watching Billy Penn and a couple of others on Youtube on pickup repairs and later tonight I will have a go.
In my first post I was really trying to find a reason for two pickups to fail in the same way and in the same position on the guitar. Or was it just bad luck?
Thanks again .Ken

Thanks for that Mark. I'm having a play with a pickup later tonight.

Hi, this might not be the case with your guitars, but since the players hand usually rests closer to the bridge pickup whilst playing, there is usually more tarnishing or corrosion on bridge pickups, and greater likelihood of failure due to moisture getting inside the pickup. I'm not familiar with that particular guitar but both pickups are probably the same, and putting the two good ones in one guitar would be a good way to know for certain that it is the pickups themselves that are the problem. Good luck with them.

It has to be something along those lines I think your spot on.
Thanks

Hi advice required again. I have just built up the first body electrics using my two good pickups and original wiring (no bridge, strings or neck) and everything seems to be working. Spotted something I have never come across before. The pickguard amplifies through the amp if you stroke your finger gentle along it's surface even at low volume.Is this normal with these old guitars?

What is probably happening is that you have microphonic pickups. When the coils of a pickup are loosely wound, or there are other loose parts within a pickup, it can be sensitive to all sounds just like a microphone. This is why many pickups are potted in wax or other substances - to stop the vibrations that cause microphonics. Wax potting was less common in the '50s and '60s.
