The Blackstar FS-19 is a two-button footswitch designed to work with specific Blackstar amplifiers, most notably the St. James series. Its primary functions are to provide hands-free control for channel switching and to engage the boost function on the amp’s second channel. This allows a guitarist to switch between clean and overdriven tones and add extra gain for solos without having to touch the amplifier’s controls. It’s a simple, rugged accessory that is essential for gigging musicians who use these compatible amps.
