    Hey Guys, trying to replace my pickguard on my Fender 1995 USA P-Bass. The Tone knob set screw is buggered up to the point that I can not get that lil thing to turn. It is a tiny flat head set screw on a solid shaft in a chrome knob. Looks like it may be a brass screw?

    It was full of grime from nearly 20 years of playing live and practice's. I can see the head and it is not stripped, just really stuck. Have been soaking WD40 (applied w/ a tiny brush) in the hole and used a small flathead screw driver. And nothing. It worked on the Volume, but not the tone....

    Any tips? Should I seek out a better cleaner/lube or better tool?

    I would try some penetrating oil in the screw hole. Let it sit for a few hours and try to loosen it again.

    WD is a moisture displacer- sort-of does some other things on the side.
    PB Blaster is a penetrant/ lubricant: the best for getting stuck stuff loose, even rusted.
    ATF fluid will work in a pinch.

    Yes. Get the right screwdriver. You'll know because it fits "right" with very little play. You can apply more torque with the correct tool before the head strips.

    WD works ok, but there's better stuff. Lacquer thinner, brake cleaner and carb cleaner are my faves. If you've got a friend that's into old machinery, like antique cars, motorcycles etc, let them have a look.

    Like JustForSport said, ATF works good too. And if you've got a nitro finish, be very careful with all the stuff mentioned in this thread.

    I work at a motorcycle shop... I have everything at my fingertips.

    Thanks!

    WD40 won't get you far at all. As mentioned previously, PB blaster is a fairly safe bet. It's gotten me out of numerous similar pickles.

    Put a little gasoline on it with the brush, just a little.

    If you have a pointed tip for your soldering iron, or even a flat tip small enough to reach the set screw, warm up the iron and put the tip against the setscrew for a minute and see if it won't come loose.
