The Resonators oscillating magnetic field offers a spectrum of frequencies from

which only string vibrations in phase are amplified. Finally, the frequency with the

largest amplitude is the winner. This frequency falls into feedback. At the same

time, reverse phase vibrations are damped. The amplitudes of the harmonics

change from zero to maximum along the guitar neck. However, phase and

amplitude changes along the guitar neck are the reason for the different feedback

harmonics on different Resonator positions.

If you like to go into more detail, you can see that the pickup selection has an

influence on the feedback harmonics too. Since the Resonator input comes from

the selected pickup, amplitude and phase of the magnetic oscillation depend on

the pickup position. The neck pickup for example shows much more key tone

amplitude than the bridge pickup where the amplitude of the first octave is much

smaller. As a consequence, the pickup selection also controls the feedback

harmonics. You can check this out simply by pickup switching while playing

feedback.

Last but not least the frequency characteristics of the pickups itself influence the

feedback harmonics. All this together makes clear why the Guitar Resonator

sounds individual depending on both, your instrument and your playing style.
