The Revival Pickups RPS2 Grey Bottomed Blues Vintage Style Alnico 5 Single Coil Neck Middle Bridge Pickups Set for Strat Style Electric Guitar, White. Fits Strat style electric guitar, neck/middle/bridge position. During 1964, grey bottomed pickups started showing up on the Strats that the players we all know and love use. The pickups got hotter, the magnet quality also improved and started to have much more consistency than they're early counterparts. This resulted in a pickup with more snap and more pronounced dynamics in terms of your pick attack. This set also features hand bevelled magnets, with consistent reproductions of the Alnico 5's that were used very commonly during this era.. Also featured on this set is our revolutionary polepiece stagger which is slightly different than a traditional Strat where they used to use a wound G, instead of a plain G; this allows for our pickups to achieve the best string balance on most instruments as much as possible. Neck, Middle and Bridge pickups all feature Alnico 5 magnets and have RWRP in the middle position. String spacing: 52mm (2-3/64 inch), mounting screw holes spacing: 76.5mm (3-1/64 inch). Resistance (neck/middle/bridge): 6.2K/6.5K/6.8K, tolerance: 0.5K; wiring: 2P. Package includes: 3 pieces pickups and mounting accessories. Note: Our screws maybe will not fit your usage, please use your own if you can.
