The Alesis ASP-1 MKII sustain pedal combines professional reliability with universal compatibility in a compact design that’s built to handle any performance situation. This sturdy footswitch features a fast-acting, quiet pedal mechanism that responds immediately to your playing, while the attached 5-foot cable with 1/4” (6.35mm) plug ensures you’re ready to connect straight out of the box.
The pedal’s low-profile portable design makes it perfect for musicians who need reliable performance across home practice sessions, studio recordings, and live stage work. Its non-slip bottom keeps the unit securely positioned during intense playing, while the compact form factor means it won’t take up valuable space in your setup or gig bag.
What sets the ASP-1 MKII apart is its built-in polarity switch, providing seamless compatibility with virtually any digital piano, portable keyboard, synthesiser, MIDI controller, or other instrument requiring a non-latching momentary switch. This universal approach means you can confidently use one pedal across your entire collection of electronic instruments without compatibility concerns.
