Diki,
I just want a simple (inexpensive) volume pedal to control the volume on my version of Yamaha's Sweet Voices.  I've created quite a few of my own, and I currently use the D-Beam on my Roland.  I want to use a volume pedal for this so I can assign the D-Beam to another function.
The pedal doesn't have to be top quality.  I no longer play out.  I do my music as a hobby now, so an inexpensive pedal for home use is all that's needed.
