WS did a piece on Riedel about 2 years ago and the Riedel-needle pronunciation was specifically stated in the article. Maybe worth a look back, if you want to flaunt it to your mates. Kinda' like the Moet (this damned keyboard won't let me put the two ..'s over the o). Since the founder was Dutch, the French pronunciation rules go out the window, and it sounds a bit like Mo-et, with the e very soft.
