Abstract: A guitar multi-effects pedalboard is provided. The pedalboard has one or more footswitches, an electronic display, and a memory storing guitar-effect presets for processing an inputted guitar signal when the processing is triggered by pressing a footswitch. The presets include signal chains with two or more guitar-effect pedal simulators that simulate two or more guitar-effect pedals. The pedalboard also has one or more processors coupled to the electronic display and the memory. The processors are configured to process an inputted guitar signal when the processing is triggered by pressing a footswitch. The processors are also configured to display, on the electronic display, an image of the signal chains, which includes an image of pedals and an image of existing simulated connections between pedals. Signal routing in the signal chain may be changed by touching the image of a pedal and dragging the image to a destination position.
