I delivered a Hammond Aurora to a house many years ago, it was a posh house they had dogs. The chap I was with love to demo and after we had put it in position the lady made us a cup of tea and she listened to use playing for about 60 minutes. After about the fist ten minute we could smell dog sh*t, we both looked at each other and it appeared to get worse the more we played. We just ignored it, we packed up and ready to go and looked down, my friend had it on his foot and by now it was on over bass peddles and up into the swell, the Leslie fan was circulating the smell around the room, we just left it there and went!
