I hope not... The new gunshots in GBU was the worst thing about the whole restoration IMO.
Sergio enjoyed playing with the design of the sound. They had a lot of meetings to discuss it. He hated silence. For instance, the revolvers are in fact Winchesters, and the Winchesters are little cannons. They sent the sound man off to a valley near Rome, where there are no roads or distracting noises. Sergio sent the man, who came back with "ping-pong-pung", ricochets and echoes. It wasn''t electronic. It was recorded in a natural setting, because he wanted air and atmosphere
I''''ve never seen so many gunshots wasted so badly... :''''(
