String Action - Peavey Spectrum Bass Owner's Manual

String Action

String action refers to the distance between the strings and
the frets on a stringed instrument. Peavey technicians care-
fully set optimal string action on each bass guitar before it
leaves our factory; however, changes in temperature and
moisture (humidity), changing string gauges, making neck
adjustments or tuning can alter string action enough to
require a height adjustment to restore your guitar to factory
specifications. Undesirable low action causes buzzing, while
abnormally high action makes your bass difficult to play.
