A piezo disc will sound the same on the top as on the bottom, assuming the bottom is not a bridge plate.

Archtops are a challenge, since getting inside can be very difficult.

The best place to mount them is inside on the spots where the bridge feet bear down.

Best outside place would be as close to the bridge feet as you can get, either behind or to the side. If you have a choice, pick a spot where there is no brace underneath.

With a K&K like device, you'll get a decent sound but will likely have feedback issues, even at moderate levels.
