About Acoustic Feedback

Feedback usually occurs in the lowest octave of your instrument, gen- erally with two notes about a half step apart. The lower type of feedback (cavity resonance) starts when the sound pressure coming out of the speakers excites the resonant air chamber inside your instrument. We have found that it is effective to tune out an instrument’s cavity reso- nance feedback with the Anti-Feedback (notch filter) in the Loudbox

100.For acoustic guitar this occurs at G# on the low E-string, or at about 100Hz. Turn the Anti-Feedback knob to about 11 o’clock to dial out this resonance. Note that the circuit can be effectively defeated by moving the dial to the OFF (7 o’clock) position.

The higher range of feedback (top resonance) usually starts about a half or whole step above cavity resonance of the instrument. Top resonance feedback happens when the sound pressure coming off the speakers excites the resonant frequency of the soundboard of your instrument. For acoustic guitar this occurs at A and above on the low E-string. Push the Phase switch in and out until you find the position that subdues top resonance feedback.
