I am actually amazed that I read so many mails about Yamaha hammers being so hard. Could it be that Yamaha's prepared for the US have harder hammers than the ones prepared for Europe? II remember a time when there were stories here (in Europe) about US piano's sounding completely different but I have no real knowledge about that. Anyway, I do remember the early Yamaha's here in Holland, and they were hard indeed, like granite. That all changed in the seventies and they even became totally soft at the introduction of the new C series in 1995 but that had to do with the fact that the our Japanese colleagues started to use pneumatic voicing tools. They simply overdid it. Today, it seems as if the English made Yamaha's are too hard and the Nippon Gakki ones are back to a pleasant normal. The CFIII-S has Wurzen felt, which makes all the difference in tone building from the start. Friendly greetings, antares the Netherlands www.concertpianoservice.nl www.grandpiano.nl btw, we sell Japanese needles that only break if you have no experience with voicing.
