    Is the a trick to soldering the black wires to the bottem of the pots? I'v been trying for about 45 mintues and I just can't get them to stick to it. Thanks

    What color are the back of the pots? If they are silver/grey, then just make sure your iron is heated up properly. If they are gold, you will have to file off some of the coating to be able to solder to them.

    I have silver pots. I'm using ne of those cold heat soldering irons, and I think that batterys are just going bad. So I'll try again later.
  5. If you're soldering to pots then you may want to reconsider your wiring design.

    That's the way the wiring diagram from fender's website says to do it.

    If you shield your cavity with copper foil tape it really isn't necessary to solder to the back of the pots, since they will be grounded from contact with the foil, plus the whole cavity will be shielded anyway. The point of soldering to it is to shield it.

    Your problem may be with Cold Heat. From anyone who knows how to solder and does it plenty, I pretty much hear it's a piece of trash over and over.

    However, just rough it up with Sandpaper as long as the pot is metal.

    Get a real soldering iron, you will be much happier with the results. :p
  10. The problem with soldering to the pots (other than that it's hard) is that you want each part of your circuitry to have only one path to the ground. If you've got foil that all the pots touch, and then they each get a wire on their casing as well then you'll make a loop. It would be easiest to send a wire to only one pot and let the foil shielding ground the other casings. Even easier would be putting a ring lug on the end of your ground wire and putting it around the threaded part of the pot like a washer. I realize that Fender's wiring diagrams are different, but Fender has some strange ideas about how to wire an instrument.

    If you don't have any foil on your pickguard then you will have to ground each pot casing somehow. You might want to consider adding some though, since it will help sheild your circuitry.

    If by some chance the "Cold Solder" junk ever gets the pot hot enough to flow solder, it will have been almost hot long enough to have melted everything inside the pot. Useless.

    You want a 40W iron so you can heat the pot casing quickly so the solder will flow but the insides don't cook.

    C'mon. A Radio Shack iron is like $9 and you can get a real Weller at Home Depot for $15. No excuses. Do it right and it's easy.

    That "Cold Heat" stuff counts on having a thin wire to solder to. What these soldering irons do is they send a very low voltage, but high amp bit of electricity through a small wire, thus heating it enough to flow solder. It is not for anything thicker than 16 ga. wire.

    I saw on TV where you can use "cold solder" to repair
    guitar strings. Anyone know if you can repair bass strings too?

    no, you cannot repair bass strings. they are to thick, and if you WERE able to fix them (say, after a breakage) it would totally mess up how they sounded. How can you fix a guitar string, anyways?
