Some players put their thumb on the next lower string when plucking in order to dampen the sound that would occur from the plucking finger.
E.g. if you play the A-string, and your thumb is resting on the E-string, your plucking finger touching the E-string does not produce a noticeable sound any more.

to be honest I do do that, i use the floating thumb where my thumb is on string below one im plucking, but as im plucking my finger is hitting the muted string and this seems to create the sound. its not always noticeable, but its certainly there and is not something I've recalled when playing previous basses. I guess its partly technique but Im thinking there must be something else thats making it worse / more noticeable and was thinking that it may be my technique of stringing perhaps.
The action is on the low side (as low as can go without fret buzz), but then when increasing action it does lower the noise a bit, but then makes the bass harder to play.
The strings are Ernie Ball Cobalts on one bass and D'Addario EXL160's on the other. More noticeable on Cobalts with a pretty hot humbucker.
