Lehle Stereo Volume

I use a moderately complex keyboard setup, and use stereo volume pedals to fade different sound modules in an out of my base tone. I purchased this pedal based on the great reviews, but after trying it out, the pedal tension is simply too light for professional use. I cannot spend all my time focusing on my pedal tension while I'm playing. I need a little tension so that when I take my foot off the pedal, it simply stays where I had it. But ANY movement at all by my foot, and the volume pedal goes to minimum or maximum instantly. This is with the tension screw set to max also. I'm not sure if I got a bum unit, but I use volume pedals for my guitar (Ernie Ball and Headrush), and have never had a pedal tension issue. To me, I simply can't recommend a $300 pedal that just flops around.
