Ok, so I recently picked up a second mpc identical to what I play on a regular basis, and was curious how many people have picked up a second piece as a back up and not even played the piece; I was pondering this, I only got the 2nd one as a precaution to have around if the original ever is damaged. I have no reason to try to replace the first, I am happy with it. Anyhow, in the event the main piece was damaged, I know I have the closest thing to replace it with. I just have the feeling trying the new one out and comparing it to the main piece is opening a can or worms--I figure if I needed to play it I could get used to it, but I don't need to know any more about it until then...
