As rock music developed and grew in popularity, amplifiers became
larger and featured higher wattage, and the music became louder and
more powerful sounding as a result. This led to a call for a more
versatile pickup that could split coils through a push/pull knob and
prevent microphonic feedback from occurring when the volume was
turned up to maximum levels. Gibson answered this call with the
introduction of the revolutionary 490T and 490R pickups ("T" for
treble and "R" for rhythm), which have the traditional
characteristics of the original Patent Applied For pickups, but
with two key modifications. First, a four-conductor wiring scheme
allows the 490s to be connected to any push/pull knob, which lets
players split the coils and increase versatility. Gibson also
introduced wax potting, which does away with any air space,
minimizing microphonic feedback. The 490R is a humbucker with the
tonal characteristics of an original Patent Applied For, with a
slight increase in upper midrange response. The 490T bridge pickup is
calibrated to match the 490R, with pole pieces aligned a little
further apart to accommodate the spacing of the strings at the
bridge, which is different than the spacing of the strings at the
neck.
