Fender Stratocaster

This is a set of EMG SA/SA/81 pickups already wired to a selector switch, volume knob, and tone knobs. They are fully functional. The guitar input jack would need to be solder once installed. You should be able to drop this right into your strat.

Here is the detail from EMG's website:

Back in the early 80's the idea to add a humbucking pickup to a Strat™ caught fire. Since then we've added just about every conceivable combination you can think of, and they're all available factory pre-wired. Once you've decided on the system you want, it can either be fully or partially assembled depending on how your guitar is setup. Since all EMG's use the Quik-Connect system you can change your system at any time without any soldering.
