pre amplifier for amplifier

pre amplifier for the amplifier:

This is the pre-amplifier for the amplifier. this is the circuit to increase the sound. we use this circuit for the amp to get better sound. normally it is used with a bass tone circuit. here used 12 voltage. this is a mono-circuit diagram. for the stereo, we have to use 2 circuits to make stereo. 

5 band equalizer circuit:

This is a 5-band equalizer circuit diagram. every amp needs a good-quality bass-tone controller. we usually use volume bass and tone circuits. or bass midrange and tone. but here we use bass, semi-bass, mid, semi-treble, and treble. this is without this type of circuit board. here needs this circuit.

Always we need this type of circuit to make best quality of sound.
