Product description:The "RW/RP" in the name of the Seymour Duncan SSL-5 RW/RP Custom
Staggered Single-Coil Middle Pickup stands for Reverse Wind/Reverse
Polarity. This refers to the practice originated at Seymour Duncan in
the late '70s of reversing the winding direction and magnetic polarity
of one single coil pickup from a 2- or 3-pickup guitar. With this
arrangement, hum cancellation is achieved when 2 pickups are used
together. Reverse-wound, reverse-polarity middle pickups are for hum
canceling in positions 2 and 4 on a 5-way pickup selector
switch.Application:A high output, true single-coil pickup for warm
instruments. Perfect for Texas blues rock, classic rock, and heavy
rock.Description:Though it looks like the Seymour Duncan SSL-1 and has
that distinct vintage tone, the SSL-5's overwound coil yields higher
output, more sustain, and great harmonics. The result is a pickup that
rocks hard and cuts through the mix, but cleans up nicely when you back
off the volume. Includes white cover.Guitars:For heavier and
brighter-toned instruments with ash or alder bodies. Works well with
maple or rosewood fingerboards.Available modifications (sold
separately):Tapped version for dual output levels. Left-hand magnet
stagger.Players:Nick Lashley, Alanis Morissette, Mick Jagger, Rickey
Medlocke, Mike Estes, Lynyrd Skynyrd, and the Wallflowers.
