Here's what EMG say about the SA/SA/81 Set of Pickups
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.
Package Includes: EMG's exclusive Quik-Connect cables (3), prewired control set including volume, 2 tone controls, 5-way selection switch (black & white knobs), output jack, and battery clip, screws & springs.
