BM Brand Tri-Sonic Style Pickups — Set of 3
Standard issue on the BMG Special, these are modern replicas of the Burns Tri-Sonics that Brian May and his father installed on the Red Special and, whilst there are some technical differences, they produce a accurate reproduction of the original tone.
The three pickups are wired in series for increased output and a fuller signal. When more than one pickup is active the resultant tone is more akin to that of a humbucker, with considerably more warmth and gain than a traditional parallel wired single-coil arrangement.
In addition, the middle pickup is reverse wound and reverse polarity (RWRP) emulating the configuration employed by Brian and his father. The pickup's magnetic pole is reversed and its coils physically wound in the opposite direction compared to the other pickups. Hence, when the middle pickup is selected in combination with either or both of the other pickups in phase, a hum-cancelling effect is created, reducing noise and hum in the output of the guitar.
In combination with the phase switching system employed on the Special, the sound of the selected pickups can be tailored to produce an incredible variety of tones.
