What does an amp head do and how does it contribute to the overall sound of an electric guitar?

An amp head is the part of an amplifier that controls the tone and volume of an Electric Guitar. It amplifies the signal from the guitar pickups and sends it to the speaker, shaping the sound through settings like gain, EQ, and effects. The amp head significantly influences the tone, volume, and overall sound of the electric guitar by boosting and modifying the signal before it reaches the speaker.
