If you want to hear some of these check out the many videos of Marc Ford playing with The Black Crowes, Ben Harper, Ryan Bingham on You Tube. These are absolutely the coolest P90's available. Take an Epi Zepher Blues Deluxe and install these and absolutely smoke any 50's era rockabilly guitar. These pickups in a LP special or early 50's style LP reissue sound amazing. These will make you a better player. Alnico 5 magnets. Dog eared or soap bar style. Carefully wound to produce very sweet tone with just a touch of growl. Calibrated for neck/bridge. I don't like to overwind my pickups. Get the best tone from your guitar-then let the amp do the work. Please let me know if you use a hollowbody or solid body guitar. What your amp is like, what strings you like.
