If you're familiar with the 9000 single pedal, this won't come as too much of a surprise! This and the single are about the smoothest pedals I've ever played over the years, and they're tough as old boots too. In fact, I used to find 9000s too smooth and didn't like them until I played one for a week and then had to buy my own - a 9000 and a 9002.
There isn't much to say about them, other than they're super adjustable, super smooth and super hard wearing! I've seen some which are many years old and look like they should be on deaths door, yet they still feel amazing to play.
This new 9002 comes with a very nice soft exterior but solid case, as oppose to the old plastic hard case they used to come with. Also, there are a couple of nice updates from the previous model: no more annoying Velcro on the bottom, but rubber (which still never slips, but can be lifted from a drum mat without an award winning tug of war team at hand) and the new hoop clamp is really solid and does a great job of fitting the curve of a bass drum hoop. There are also a couple of other differences in the design.
Anyway, awesome pedal! If you need a single or double, the 9000 has my full backing. It may be pricey, but you get what you pay for!
