Re: Pickups for Explorer
Be careful with pickups that are very mid centric in a Explorer- they are already really heavy on lows/low mids, and light on high end so many pickups can sound like mud.
Since you will need to re-wire With 500K pots though, a Duncan Custom or C5 would be a good choice for bridge, and a 59 or Jazz is usually a good choice for the neck. I ran a Custom/59 in my main explorer for several years.
I'd bet that a Demon would be a really good match for an Explorer bridge.
I'd shy away from darker middy pickups like the SuperD, JB, CC, etc in the bridge.
