I've had this pad for almost two years now, so time to write a review.
First off, I'm using this pad with my ddrum3, so no 2box module.
It's a very quiet and very nice feeling playing surface. The triggering is of course perfect because of the FSR-technology. The only minor drawback with the surface itself is that it's a bit slippery, not like a normal coated head, but more like a clear one. The surface seems very durable, there are still no signs of wear.
The major issue that I would like to inform of is the velocity response, which is quite different from a piezo based pad. I think the best way to describe it is that it "bottoms out" with harder velocities. In other words, the output doesn't get very hot, but has a pretty confined range.
For modules that have several velocity curve settings, the limitied velocity range will probably be a minor issue.
My plan for the pad was to build a "snaredrum" with it, so that I would have rim, head and cross-stick zones. For this it has worked very well, and the limited dynamic range of the FSR-pad suited it quite well. When playing rimshots, the signal from the FSR is not too loud, so it works well even without any zone switching, both head and rim can play simultaneously with no issue.
The pad does require the original "inbox" or a DIY solution (which should be current limiting) to power it.
