Re: [Harp-L] feedback nightmare



i play through a danelectro centurin my mic is a blues blaster,i always get
miced . i dont always have this problem but last night was bad.my firsy
question is does the feedback come from the amp or does it start from the PA ?? what
are some ways to resolve this problem???

A technical explanation of feedback: http://www.tpub.com/neets/book8/30e.htm

Electronic solutions aimed at reducing the amplitude of the offending frequency.:
Tunable notch filters (less loss of frequencies adjacent to the feedback frequencies)
Adjustable equalizers (not as sharp/more loss of frequencies that are not a problem)
Tone controls (large change to the overall sound)


Electronic solution aimed at changing regenerative feedback to degenerative feedback:
Phase inverter.


Acoustic solution:
 Get your mic away from the speaker.
 Directional mic

Obvious solution:
 Turn that #@$%&* thing down :0)

Peace and music,
Dave
