What is the difference between a "Regular" pickup and an "F Space" pickup? I am looking to upgrade my pickups and don't know what the difference is.

- Ibanez SZ720FM (EMG 81/85)
- Ibanez RG1570(D-Sonic/Air Norton)
- Schecter C-1 Classic
- Carvin CT6M (Deep Blue on Quilted Maple)

- Mesa Boogie Rectifier Road King II w/ RK 2x12 Cab
- Boss GT-8
- Ibanez TS9DX
- Monster PRO 2500
F Space - Floyd rose tremolo, fender or any guitar thats equipped with a trem. so you would want just regular pickups
