I had a volume pedal from my now ancient "Cordovox". I hooked it up to my PSR 2000 and it works. The pedal was ahead of it's time since the pedal served two functions- Volume and Glide which would bend the notes. There was a small flexible area on the pedal that would control the glide "hands free", The output plug was a stereo plug which carried both signals. I tried splitting the signal into two plugs with a common ground and plugged them into 2 separate inputs on the 2000. One set for volume and one set for glide but was disappointed that it worked for one or the other not both. It would have been a terrific pedal had it worked for both functions.
