Electric guitar effect enhancement circuit

How the circuit works: This circuit is a high impedance amplifier. Since the electric guitar
sensor sends out an attenuated low-frequency oscillation wave, which is equivalent to the inductive impedance ,
during the amplification process, the high-order harmonics of the signal are greatly attenuated here, and
continue to change through the adjustment effect potentiometer RP, The degree of limiting of the signal peak can enhance the bass strength.
