PZM mics are great for pianos with the lid closed. Another mic to consider is a C tape. PZM mics are very sensitive and pickup other instruments if they are around so the lid needs to be closed. C-tapes are two strips that adhere to the bottom of a grand, one located near the treble, and the other near the bass. The strips are about 8" in length. These sound good and are not too tinny Alan Meyer Las Vegas PS I've been doing work in the showrooms here 22 years so I've seen It all. Good luck
