German patent application for a music amplifier featuring a modular tone modification stage. The amplifier has an input stage, output stage, and a tone modification stage containing separate effect circuits (distortion, tremolo, and reverb) connected as individual modules via plug-in connections. Each effect can be independently switched on or off without affecting amplifier operation, and failed modules can be easily removed for repair or replacement.
