Unlike many digital pianos, which are designed for semi-permanent installation in a private home and have design elements which make regular transportation difficult (e.g., permanently mounted legs, modesty panel, internal power amplifier and speakers, and a fixed sustain pedal), a stage piano generally has a portable, detachable stand, no internal amp or speakers (an output jack is provided so the instrument can be plugged into a keyboard amplifier), a detachable sustain pedal to be plugged into a jack, and a robust body. This enables a performer to remove all of the detachable parts and makes the instrument easier to transport to gigs and rehearsals.
