Recently purchased a set of D'Addario EXL190 40-100 strings.
The E string is producing a 'chorus' effect. A, D and G are fine.
I checked the string for twists, set my witness points correctly, checked the pickup heights and made sure nothing was loose on the bass.
No luck! Problem is still there. I've had XLs many times before this but never had this issue. Will I have to take this one on the chin and purchase a single .100 E?
Any ideas/thoughts welcome.
