Comments about Roland KD-9 Electronic Drum Kick Pad:
Works well with my SPD-30 Octapad and DW 3000 series double bass pedal. It's louder than I was expecting, especially on the second floor of our house. It doesn't seem to bother my wife much so I'm keeping it. I'm pleased overall, it gets the job done, just wish it was a little quieter.
Bottom Line Yes, I would recommend this to a friend
