If a uni-directional microphone is mounted outside of an instrument,
it may be offset to cut its potential to feedback, by angling it to keep
front and rear of the mic pointed away from the main sound source
GOOSENECKS: External goosenecks with uni-directional ( cardiod
or hyper cardiod ) polar pattern microphones, are usually best
pointed at the upper bout, close to the top “E” string, but not directly
at it. Keep microphone away from soundhole. Do not point rear of
microphone at sound-hole
If an internal microphone is on a flexible gooseneck you may lessen
the problems by spending time finding the best sounding spot for
placement but caution is suggested in case it moves or changes
angle slightly, you take it to a different acoustic environment, as it
interacts differently with the room
ANTI-FEEDBACK ELECTRONIC DEVICES: If used correctly,
these can help a lot at the professional sound engineer level but the
sound quality that a good microphone can deliver is incrementally
compromised by use of anti-feedback electronic devices. The
harder they work, the more elements they lose from the sound,
which defeats much of the aim of using a microphone. Non
technical players may find these rack and half rack units difficult to
use effectively
POLAR PATTERNS: For optimal sound quality, Headway
recommends that, if used, microphones should be used externally
and with uni-directional, cardiod and hyper cardiod polar patterns
