• Check that "Range" control switch is set correctly
to remove unwanted low frequency amplification
• Use EQ controls to cut frequency of feedback
• Covering or blocking the sound hole(s) of an
instrument may often help give a few more dBs of
level before the onset of feedback
• Sound absorbent materials such as drapes and
heavy banners in room may help to damp sound
reflections which cause feedback
• Where using two pickups or pickup + Mic and
feedback is encountered, increase proportion of
saddle/bridge pickup or magnetic pickup and
decrease proportion of Contact Pickup or Mic; or
Increase proportion of Contact Pickup and reduce
Mic level
• Where using Mics, avoid Omni-directional and use
Uni-Directional / hypercardiod
• Move source closer to any Microphone in use
• Electronic feedback destroyers are rack units
which, when set up correctly, automatically tune
into and attenuate the troublesome feedback
peaks allowing the remaining frequencies' volume
to be increased. However, they may be complex to
use correctly and will remove frequencies from the
sound which may defeat the point of using Mics
• The overall level may be increased by playing
harder and getting the instrument closer to any
microphones
