For now, again, off the board. I've tried a couple of times, but it still feels a bit weird, even on the flat boards. And funny thing, that I prefer mini wah on the floor even more, then full size. Because I just can not get a right sweep on my board. Tried in the first row, did not work at all. In the second raw it worked a bit better. But, after all, I realized, that better way for wah and volume, just on the floor, before my board.
