With the values above, this frequency is ~34Hz which means that the amplifier will never amplify the frequencies below 34Hz. This makes sense because in a standard-tuned six-string guitar the lowest frequency is 82Hz (low E). Even if you play a seven-string guitar (like me, hehe) the lowest frequency is 61Hz (low B) which is still in the bandwidth of the amplifier. | |
