These use vacuum tubes to amplify signals. They are prized for their "warm" organic tone and natural harmonic saturation when pushed.
These use transistors for amplification. They are often more reliable, lightweight, and offer "clean" headroom at higher volumes. electric guitar amp
While an electric guitar produces a signal, it is the amplifier that defines the instrument's final voice. Beyond simply increasing volume, an amp acts as a critical signal processor that colors the tone through saturation, equalization (EQ), and compression. 2.
