Introduction
To increase the input power of any audio device, the term “amplifier” is widely used. Audio Amplifiers are the circuits that increase the power of an audio signal. Hence, different audio amplifiers are used in different audio equipment and instruments. One of those instruments includes the guitar. So, in this tutorial, we will see how to Make Guitar Audio Amplifier. The circuit contains power amplifiers and preamplifier circuits.
Remember, not every audio amplifier is powerful enough to look at all the factors and gives the perfect increased output. For example. We consider noise a major problem. So for the large output signals, reduction of the noise is also the biggest task for guitar audio amplifiers. For this purpose, we are using TDA7052 IC which provides low harmonic distortions and noise.

Guitar Audio Amplifier Circuit
Working Explanation
In this Guitar Audio Amplifier, we give audio input at the input pin two of an IC through the 10uf capacitor. We give supply at pin 1 of an IC. The high frequency, low noise output is observed at the output pins of an IC, which are pins 5 and 6. 220uf and we can use 100nf capacitors at the output side for the filtration purpose or for smooth amplified audio.
Applications
- This circuit is basically for the portable guitar instrument but can be utilized in different power amplifiers.
- Also, can be used in speech amplification circuits.
