I have a sp-404 and an sp-202 and the 404 pads are slightly larger than the 202 pads. You'd have to compare them side by side like I did, but I can't tell a difference between the feel of the two pads. From what I can tell the Fantom X and the sp-404 use the same pads, but I have not done a side by side comparison so I can't tell. The fantom is cool, and I've watched people use the pads and make nice music. I'm not a pad person, and part of that could be because I was never an mpc head, but I don't mind using them.
