This thread prompted me to do a little research and then pick up an older, first version, Visual Volume pedal off of reverb. It looks more like an Ernie Ball with the base sticking out on one side than the later version that looks like it was designed by Darth Vader. I used it for the first time tonight. Very nice volume pedal. Nice feel, smooth sweep. It works as a passive pedal or plug in 9v power and the line of lights on the left side of the pedal comes to life.
I found the visual display easily in my line of sight while I was playing. The reference provided by the LED really helped me keep my volume under control. It was especially useful coming out of a jam where I want to bring down the level as the vocals come in. The LED readout made it easy to hit the right volume level quickly, so I could concentrate on my vocals. Similar to my experience with my first LED equipped Alembic, the lights turned out to be more useful than I anticipated.
