How do you measure string spacing? My guitar is neither a Fender nor a Gibson, and I'm not sure which one it was designed after. If I have a strat-style bridge, can I assume Fender? I just wanted to know because I'm ordering new pickups soon and I need to know which ones to get.

Just measure between the centre of the furthest away string saddles. Strat-like guitars are generally ~54mm. It also depends where you are putting the pickup. Neck pickups are normally spaced at ~52mm
