"Beginning in late 1966, the 360 and 330 series 12-string models were available in a three pickup version known as the 370 and 340 models, respectively. This example has the same electronics as the 360-12, but includes a middle pickup, which adds a midrange tone to the guitar when switched to the neck pickup, as both middle and neck pickups are wired in sync. This example has been retrofitted with a 12-saddle Rickenbacker adjustable bridge."
