Aha. This may be what I've been hearing on certain bass notes on one of my instruments. I thought I must be dreaming.pasigenyo wrote: ↑Wed Apr 10, 2019 2:15 pmSounds like a similar phenomenon with my guitar. It's like the string has a "chorus" effect and seems to come from the bridge area. Check if your saddle is too thin for the slot and if it rocks back and forth when you move it (with the strings loosened, of course). I have not been able to eliminate that effect, but I've reduced it drastically by replacing the saddle with one that doesn't wiggle. Hope this helps.

And the bass strings have not yet worn notches into the top of the saddle. ...Would be easy to explain if I could draw a picture. You might need to file more of a bevel on the back side of the saddle so the crown is sharper/more sudden.
