There is
no 3-way pickup selector switch on this version of the 459 guitar. The
left-hand rotary control pans between the two pickups in order that various
degrees of output from each pickup can be dialled in. There is then a volume
rotary control, a switch for turning the fuzz on or off, and a rotary for
controlling the “depth” of the fuzz. All in all, a very neat control
system.
