M-Audio SP-1

I used this pedal for KORG Kross SE-61. I found a problem that sometimes the sustain pedal is not working. To solve this problem, I have to unplug and re-plug to the jack, or calibrate the half-damper function in the keyboard.
Actually, the pedal default polarity is same with KORG default polarity, and the pedal has a switch to change polarity.

Even though it's primary use is as a sustain pedal, the M-Audio SP-1 also works as a momentary switch. I hook it up with my hard disk recorder (Yamaha AW16G) to pop in and out of the rec mode - great for fixing little mistakes or adding overdubs without having to erase unwanted in-between noises afterwards. So far, it has not given my any trouble, but I only use it at home where sturdyness is a non-issue.

This is a good, basic sustain pedal. It doesn't feel specially sturdy, but has lasted me a good time anyway. Big plus for switchable polarity, so it work with any sustain-input keyboard. Long lead is also good thing to have.
