Glossary &gt;Technical &amp; Sonic &gt;Buzz: The higher harmonics of 60Hz noise from a pickup or guitar's wiring that is typically emitted from lighting, dimmers and other mains powered electrical appliances. Buzz can not be cancelled by a pickup, it must be minimized with shielding in the wiring cavities of the guitar. So called noiseless pickups are not immune to Buzz. Kinman's are advertised correctly as Zero-Hum pickups. See Noise-RFI.  Can also mean gossip or newsworthy information.  Glossary &gt;Technical &amp; Sonic&gt; Hum: The 60Hz noise reproduced by pickups that originates in mains wiring and appliances powered from mains supply. Unlike Buzz, Hum can be very effectively cancelled by a hum-cancelling pickup. Buzz can only be minimized with shielding in the wiring cavities of the guitar. See also Buzz &amp; Noise.
