strange "effect"

[Gab124]

Maybe someone can help me figure out what I am experiencing. I recently changed my pickups out to try a new set. Been playing it for a few days only on my little 15watt practice amp (poor quality on top of that). When I play notes only on the e string and only around say the 15-17 or 18 frets I get a curious sound effect going on , something like a chorus. Does not matter if I pan pickups, engage or disengage preamp or adjust tone controls and it does not do it anywhere else on the fretboard or on other strings. It does not even matter if I move the amp into different positions etc. Weird. Any idea what it might be?
thanks

I have had that happen on a bass before too. i had an ernie ball stingray HH and it would do that exact thing. weird because i have owned many stingrays and only that bass did it. never found out what it was cuz i got rid of the bass pretty quick. is your E string properly intonated?

Yes, I set intonation a few weeks ago (maybe i will recheck). I did not notice this until the pickup change so I was wondering if installation, or pickup proximity to strings could do it. Sounds good in all the other positions. Did yours do it on all amps?

it did. it was there acoustically too. try playing unplugged and listen real close. it also may be pickup height too. good luck!

The chorusing effect up high is often due to the pickups being too close to the strings. Try either sinking the pickups or raising the strings and see what happens.

Hey thanks, I wondered about the pickups. I also rechecked the intonation, and what do you know it is out and mostly on the e string. I will reset tonight. This may have been the wrong forum but I could not help but think it was the pickup installation. To keep it forum specific, I put in nordy bigsplits, and so far I really like them over the bartolini they replaced.
