I've just bought the Korg heavy duty sustain pedal as I'm fed up of chasing the lightweight pedal included with the SV1.
However the new pedal wont unsustain when I lift my foot off.
Help! Any suggestions? Faulty pedal or just incompatable?

Can anyone recommend an alternative?
I would really like to get this sorted before my next gig at the end of this month
Thanks in advance

Jon
