Inoffensive to whom?
I was pleasantly surprised when I got my Keilwerth stencil a few years ago. The cats and dogs who, with my previous soprano, would run to the farthest corner of the house and cower. With my "new to me" sax, they would actually stay in the room with me. The cats eventually wander off, because they don’t like loud things, but no more running for their lives. My daughter’s dog will still “sing" with me when she visits, but no more howling and whining with her tail tucked between her legs as she slinks away.
I am still not sure what to make of it, but I also prefer the sound.
