How we ranked these sustain pedals
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: portable sustain pedal
Check the polarity switch
A polarity switch flips the pedal signal so the pedal works with keyboards that expect the opposite polarity. The Donner, Alesis and midiplus pedals have polarity switches, and the VALDI pedal has a conversion switch for all brands. If your keyboard holds notes down when the pedal is up, flip the switch.
Pick piano-style or footswitch
Piano-style pedals look and move like an acoustic piano pedal, while compact footswitch pedals sit flat on the floor. The Casio SP-20 is a piano-style pedal, and the Alesis pedal works as a momentary footswitch. The Donner and VALDI pedals are universal pedals for keyboards, pianos and synths.
Check cable length and grip
Cable length decides how far the pedal sits from the keyboard. The Donner pedal has a 1.6 m cable and the Alesis pedal has a 5 ft cable, while the VALDI pedal has an extended cable. Grip keeps the pedal put: the Donner pedal has 6 slip-resistant pads, the Alesis pedal has a non-slip bottom, and the VALDI pedal has a natural rubber base with a diamond pattern.
