Bill Maxim mentioned a bizz in a Steinway B. A few people mentioned some possibilities. Another possibility not mentioned is that one of the string tails might be just barely touching one of the rear duplex bars. I was called in on a similar situation with a brand new Steinway a few years ago - either an M or an L - I don't rember now. It was giving the dealer's technician a fit. He had put a felt wedge between one of the beams and a soundboard rib as a temporary fix. I found the problem, which turned out to be one of the string tails at the very low end of the rear duplex that was barely touching one of the duplex bars that it was not supposed to touch, and buzzing against it. One did not have to play that note to make it buzz. It did it on several different notes. Small item, big noise, easy to fix, after I found it. Jim Ellis Jim Ellis
