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.
- Polarity switch weight 2
- Half-damper / continuous weight 1

Buying advice: sustain pedal for keyboard
Pick piano-style or compact first
Pedal style is the first split. The SP-2 is a piano-style pedal with a chrome foot pedal, while the SP-1 is a compact pedal from the same brand. The karmiero, CAIHONG and VALDI pedals each have a switch on the side. If you want a piano-style pedal, the SP-2 fits; if you want a compact unit, the SP-1 fits.
Check cable length and plug type
Cable length decides where the pedal can sit. The SP-2 includes a 6 foot cable, the SP-1 includes a 5 foot cable and the karmiero includes a 91 inch cable, each with a 1/4 inch jack or plug. The VALDI includes an extended cable with a 1/4 inch jack. Match the cable to the distance between your pedal spot and your keyboard, and check the plug your keyboard takes.
Check the switch and the base grip
Every pick here has a switch for matching your keyboard: the SP-2, SP-1, karmiero and CAIHONG name a polarity switch, and the VALDI names a conversion switch. Grip matters too: the SP-2 has rubber pads, the karmiero has a rubber bottom, the CAIHONG has a non-slip mat and the VALDI has a natural rubber base with a diamond pattern. Pick the grip that suits your floor.
Frequently asked questions
Do I need a polarity switch on a sustain pedal?
It helps when you switch keyboards. The SP-2, SP-1, karmiero and CAIHONG pedals have a polarity switch, and the VALDI has a conversion switch that serves the same purpose. If your keyboard sustains without pressing the pedal, flip the switch to the other setting.
What cable length comes with each pedal?
The SP-2 includes a 6 foot cable, the SP-1 includes a 5 foot cable and the karmiero includes a 91 inch cable. The VALDI includes an extended cable with a 1/4 inch jack. The CAIHONG has a 1/4 inch jack input.
Which sustain pedal has a warranty?
The VALDI is the only pick here with a 1-year warranty. It also has a conversion switch, an extended cable and a natural rubber base with a diamond pattern.
Can I use a sustain pedal with any keyboard?
These pedals are built for wide compatibility. The SP-2 works with all electronic keyboards, the SP-1 works with all M-AUDIO MIDI controllers, and the VALDI works with all piano brands. The karmiero names Yamaha and Casio among its keyboards, and the CAIHONG names digital pianos, synthesizers, MIDI and electronic keyboards.
