Why do Fender Mustang guitars have solid covers with non-exposed magnets and not covers like Strats with raised exposed poles?
The Fender Mustang has (2) three position switches, the center being off. Sliding the lever switch either way from center reverses the electrical phasing of the coil in the pickup. The pickups are in series with each other and can be in phase in two positions or out of phase in two positions. Reversing the electrical phase of the coil can make the pickup noisier if allowed to come in contact with your fingers or strings. The purpose of the solid cover is to insulate the strings and fingers from touching the poles. If the strings touch the pole, it could cause the pickup to short out. If the fingers touch the poles, extreme buzzing can occur. Both can happen when reversing the electrical polarity of a pickup with exposed poles. If you install vintage style Strat pickups with raised poles, you will have this problem. Vintage style pickups have the coil wound directly around and touching the rod magnets. When the coil polarity is reversed the inner coil becomes positive and makes magnet r
