Guitar amplifiers help define a player's tone, with early tube amps from Fender and Marshall setting the standard. Brands like Vox and Mesa/Boogie further expanded tonal possibilities with distinct British and high-gain sounds. Amps range from small practice models to large stage rigs, with tube and solid-state designs catering to different playing styles. Modern digital modeling amps offer even greater flexibility. Whether for gigging, recording, or practice, amplifiers shape the way electric guitars interact with effects and dynamics.
