I like the Behringer VP-1 so much, I have two of them!. They are from different batches, thus the different painting on the front panel, but the sound the same (and great) to me. Sometimes I use them in a stereo configuration, with one channel handling the Left channel and the other one dealing with the Right one. The out-of-phase and de-synchronization between the two pedals adds new sonic texture to the sounds, and makes the MicroKorg sound amazing.
One word of caution, though. These pedals do not handle the hot Line signal as well as the newer pedals from Behringer (indeed they are not rated for keyboard use), so they sometimes distort the sound a little bit. However, this adds an analogue warmth to the sound, as long as you keep this distortion in check.
I hope you enjoy it as much as I do.
