To prevent howl, would delaying the signal-path help?
Low volume or headphones helps, but play guitar "live" and problem of feedback surfaces.
An idea I had is to use a passive analog delay-line in the input circuit.
I have a circuit for this, somewhere...
Hopefully this would decrease the feedback frequency to sub-audible (my theory anyway).
Would this work in practice?
Otherwise how do stage performers overcome this problem?
Guitar is nylon-string acoustic, fed to amp up to 4m away via several alternate methods:
600 ohm balanced mike on stand, into FM transmitter,
acoustic clip-on soundboard pickup (in hole),
also tried an old turntable pickup, sensor pressed on soundboard (poor audio response).
If I remember, the delay-line used multiple inductors / caps in a "pi" network.
Cheers, Clive.
