Pedalboards, power supplies, and cables form the foundation of an effects rig, organizing and powering multiple pedals while ensuring signal integrity. Early players simply placed pedals on the floor, but as setups became more complex, dedicated boards became essential. Key manufacturers include Pedaltrain (Classic and Novo series), Temple Audio (Duo and Trio boards), Voodoo Lab (Pedal Power series), and Strymon (Zuma power supply). Pedalboards range from minimalistic to highly modular, while isolated power supplies prevent noise and interference. These are crucial for gigging musicians needing quick setup, reliable power, and clean signal paths.
