Dauz 6" pad. It did trigger a roland sound module but it wasn't sensitive to the light (p) soft notes. Either I am expecting too much, the sensitivity on the module needs to be adjusted, or the piezo internal trigger needs to be replaced so that the lighter dynamics can transmit. I don't want to spend any time playing with adjustments so here it is for cheap. Structurally sound top and body. The rubber is good. The plastic clamping cap on the bottom has a scratch or the beginnings of a crack, but it tightens down nicely. Thanks for your consideration.
