How we ranked these sustain pedals
Every pick ranks in Amazon's best-seller list for its category and has 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: professional sustain pedal
Check the pedal type first
A piano-style pedal copies the shape of an acoustic piano damper pedal, while a compact footswitch is a smaller momentary switch. The On-Stage, KORG, Casio and Nord pedals here are piano-style, while the Alesis is a compact footswitch. A polarity switch matters when a pedal sustains in reverse on your keyboard: the On-Stage and Alesis pedals include one. Half-damper control gives partial sustain on keyboards that support it: the KORG and Nord pedals list it.
Match the pedal to your keyboard
The Casio SP-20 works with Casio keyboards and digital pianos with a pedal jack, and the Nord NSP2 is made for Nord Stage 4 keyboards. The KORG DS-1H is made for KORG keyboards. The On-Stage and Alesis pedals use a polarity switch for universal compatibility with instruments that have a 1/4-inch sustain input. Check your keyboard pedal jack type before ordering.
Weigh warranty and cord length
Four pedals here carry a 1-year warranty and the Nord carries a 2-year warranty. Cord length also differs: the On-Stage cord is 6 feet and the Alesis cable is 5 feet, while the Casio pedal has a long cord. If your keyboard sits far from your feet, a longer attached cord saves an extension. Keep the receipt with the packaging until the pedal is in use.
Frequently asked questions
Do I need a polarity switch on a sustain pedal?
It helps when a pedal sustains in reverse on your keyboard. The On-Stage KSP100 and the Alesis ASP-1 MKII include a polarity switch that reverses the up and down signals.
What is half-damper control on a sustain pedal?
It gives partial sustain instead of only full sustain, on keyboards that support half-damper control. The KORG DS-1H and the Nord NSP2 list half-damper or continuous sensor control.
Will the Casio SP-20 work with a non-Casio keyboard?
It is made for Casio keyboards and digital pianos with a pedal jack. Players with other brands should pick the On-Stage or Alesis pedal, which use a polarity switch for universal compatibility.
How long is the warranty on these sustain pedals?
The Nord NSP2 carries a 2-year warranty. The On-Stage, KORG, Alesis and Casio pedals each carry a 1-year warranty.
