so since i can't figure this out, i'm opening this question up for people who know more than me:

i'm doing work on a non-fender hollowbody with p90s, and i was working the knobs off the pot shafts (so i could put some vitamin q caps in) and broke one, so i figured while i was in there i'd switch the pots out.

so i grab four cts pots and replace all four pots using the tried and true "copy exactly what the factory did method"...and i've got a few issues.

These are 500k (just like the originals) and i'm pretty sure all four are logarithmic...the volume pots cut out pretty much at 5. the interesting thing is that the tone, when rolled off to about 2.5 and lower, actually cuts the volume out completely....basically, the tone gets warmer and warmer and then the volume drops out around there. another interesting thing is that when both PUPs are selected, killing the volume on one pot will lower both PUPs from about 5 and lower.

i'm pretty sure i messed up one...when the tone is at 0 and i strum hard the sound comes thru very crackled and sporadic. the other one does not send a signal when turned to 0.

i tested all the parts and all were within 3% of 500k...i matched. also the caps definitely work.

SO...if i directly copied the previous electronics (which functioned normally), then what did I do wrong? did i mess up the wiring (based on the crackle on the one tone pot)? did i mess up when buying the wrong kind of pots? let me know what you think, and help would be much appreciated...

For starters:

What is the DC resistance of your pickups?

Are you using a treble retention circuit?

Have you applied excessive and prolonged heat to the back (can) of your volume pot(s)?

If one of your tone pots is acting like a volume pot and/or you get a weak, distorted audio when it is turned down, that pot isn't grounded properly.

If you could post clear, large pictures, that would be most helpful.
