i have a dimarzio pickup that's really low-end and muddy and sort of empty sounding.

could i send it to a pickup maker to have it re-wound to be brighter and fuller?
or should i just sell it and buy a new pickup?
Rewinding costs a lot of money for time, you might get a custom sound, but you might also be dissapointed. try winding one yourself using a fishing pole rig, if else, just buy a new one.
You just LOST the game >: P

After years of extensive research at Yale, it is determined that the game does not, in fact, exist.
