Pretty sure these are uninstalled pickups, but the covers aren't the stock ones with the logos and have seen some shop wear. The leads appear to be uncut and never soldered. Either way, they are a pretty sweet set of stacked hum-killing pickups from one of the premier pickup makers. New, they retail at $170/set. These are 4-lead pickups, so you could actually wire them with a series/parallel switch for more tonal options. Not sure if running single is possible or recommended, that may be a question for SD. But I do know that S/P is possible and capable. If you're not picky about aesthetics, this would be a chance to snag some way cheaper! Get rid of those low-output, noisy singles and add some beef to your J. $75 shipped for the set to the US Paypal PM if elsewhere Would trade for some DiMarzio Model Js, if you have a set.
