Pre amplifier circuit diagram

This is a Bass treble circuit diagram. I always need this circuit to make an amplifier. if we want to make a good-quality of sound then we need this circuit. every amplifier makes a raw sound. amplifier only makes the sound lower to higher. like small sound to big sound. this circuit is used as a pre-amplifier to make the quality of sound. if we want to make the sound as we want then we have to use this circuit. in this circuit used 4558 ic.

This is the easy preamplifier circuit diagram. We use this circuit to the amplifier to increase the sound. here used one transistor.

This is a PCB LAYOUT MASTER STEREO PRE-AMPLIFIER. Every amplifier needs this type of pre-amplifier to produce good sound
