Bass booster circuit diagram 

This bass booster circuit is made using the quad op-amp ic LM324. This op-amp ic has  4 operational amplifiers, but in this circuit, only 2 op-amps are used. This circuit provides Low low-pass filter of input audio, which produces a Low frequency of input and blocks high frequencies.

Connect the circuit as the diagram below. Give input through the 47K resistor at pin no 2, another 47 K resistor is connected between pin 1 and pin 2. Pin 1 is the output pin of 1st op-amp, and this output pin is connected with the 2nd op-amp’s input inverting pin 6 through resistors and capacitors. Pin no 4 is connected with +9v supply. Pin 11 is connected with -9v and connect the ground with the given terminals in the diagram. Use a dual power supply for the operation of this circuit.RV1 is a 100k preset for adjusting the level of frequency. Pin no 7 is the output of 2nd opamp, and this pin is used in this circuit as the output also. The output must be connected to the amplifier input.
