If the Q-point is set too close to cutoff (zero current) or saturation (maximum current), one side of the waveform will flatten out early, causing asymmetrical clipping, which generates rich, warm second-harmonic overtones. 4. Power Supplies and Rectification
Frequency response describes how an amplifier affects different frequencies within the audible spectrum. A "flat" response would amplify all frequencies equally. However, guitar amplifiers are deliberately . The power supply, the choice of components, and the circuit topology all contribute to a unique frequency response that gives each amplifier its characteristic "voice." This is the basis for tone shaping. guitar amplifier electronics basic theory pdf

The unsung hero of any amplifier is the power supply. It takes alternating current (AC) from your wall outlet and converts it into the steady direct current (DC) required to power the internal components. A "flat" response would amplify all frequencies equally
Understanding how the signal travels through the circuit helps demystify how different knobs affect your sound. Inside a Guitar Amplifier – Part. 1 - Roland
