FV-500-H : Superb!

Reasonably priced and very well made. Aluminum construction means that it's a lot lighter than its size would suggest. Just be aware that it's a large pedal and takes up a lot of space on the pedalboard. Most importantly (for me at least), it has a nice taper that is excellent for doing volume swells, which is not the case with some other pedals. The torque is adjustable as well so you can dial in the 'feel' of the pedal to your liking. The only disadvantage I can think of is that it has a potentiometer inside, which, if you use the pedal frequently, will eventually wear out and will have to be replaced. Potentiometers are also notorious for developing unwanted crackling noises. There are pedals on the market (Morley etc.) that use a light sensor in place of a pot, but the one I tried had a different taper that was too abrupt for my purposes.
