In the past, if you wanted humbucker tone, P90 tone, and Strat tone, you would have needed three different guitars. But now, the P-Rails humbucker delivers all three sounds in a pickup that is a drop-in replacement for any stand sized humbucker slot. Using any 3-way (on-off-on) mini-switch, each unique hybrid humbucker can be split to give you an super fat P90, or it can be split to the Rail coil for Strat like tone. With both coils on, you get a big sounding humbucker that packs a nice full punch. The neck version is wound RWRP so that, you can use both P90s or both Rails together and get hum-canceling tone. Hand built in Santa Barbara, CA, each P-Rails humbucker uses a pair of alnico 5 bar magnets, comes with a 4-conductor leadwire for all of the wiring options, and are vacuum wax potted for squeal free operation.
