Once in a while I hear a distortion on the upper frets on all strings. Could this be the old pickups?

As it is not all the time, I wouldn't suspect the pickups.
Look at other items, amp, cables, volume pedal, effects, etc. |

| I agree with Jack. Distortion is usually a problem with the amp or speaker, or sometimes something in the sound chain going into the amp. |

Back down your pre-amp a bit also, see what happens. I agree with Donnie and Jack.
Check for moisture and/or build up [oxidization] in the jack socket!

I don't know if you have observed this in different amps or not. I have a Nashville 400 and it had been setting in storage a long time. I got it out and hooked it up and it would distort / cut out when I hit certain notes. Turned out the speaker plug on these plugs into the chassis upside down and has not strain relief and was loose enough to vibrate on certain notes.

Jim jogged my memory...I also had another thought, if it's a Peavey...The Reverb connector above the speaker are known for moisture corrosion and cause all kinds of distortion, as the signal goes through the reverb tank...I have had that on many peavey amps.
Pull it off, clean pins and load connector with dielectric grease.

Speaker connectors (the blade ones) on certain Peaveys are notorious for that especially after standing unused for a while. Also some 1/4" jacks were real bad although they do usually clean up OK with contact cleaner or Inox. I have a 130 bass amp that does it regularly vintage early/mid 90's.

A bad PU, when put on an ohm meter, will usually show real high numbers. Way out of the normal range of 7 to 18k. It would sound weak and out of phase. RP

Or abnormally low numbers: they can short as well as open.

"Out of phase" is a relative term. Out of phase with what?

 Barry, have u checked all your signal cables? Some cables develop probs as they age and create capacitance and resistance issues that can roll off the topend  |
