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.

Check polarity switch first
A polarity switch decides which keyboards a pedal matches. The M-AUDIO SP-2, the AODSK pedal and the UPELLA pedal have a polarity switch, and the midiplus SP-2 has a positive and negative pole switch. If switch type matters to you, compare the switch line for each pedal before buying.
Compare cable length and plug type
Cable length and plug type decide where a pedal sits. The M-AUDIO SP-2 uses a 6 foot cable with a 1/4 inch jack. The AODSK pedal uses a 63-inch cable with a 1/4 inch input plug. The UPELLA pedal uses a 6.25 feet cable with a 1/4 inch straight plug. The Casio SP-20 and the midiplus SP-2 use a 1/4 inch plug. Compare cable and plug details before buying, since plug shapes differ.
Match pedal style to your setup
Pedal style and build decide how a pedal sits on the floor. The M-AUDIO SP-2 and the Casio SP-20 are piano-style pedals. The AODSK pedal uses a chrome metal pedal with a non-slip rubber base. The UPELLA pedal uses ABS plastic and alloy steel with 4 non-slip rubbers at the bottom. The midiplus SP-2 uses an adjustable pedal stroke.
