Hi Alison. How're ya doin'? We've corresponded before on stuff so I'm quite certain you know the difference between a whistle,a flute, and a recorder. Mike Grinter makes possibly the most sought after flutes in trad and classical music. He also makes recorders I think, but this instrument is of no relevance to me (like many school children, my first experience of music was the damned recorder - it put me off playing music until the age of 18). He makes great whistles as well, but the one thing he doesn't do is update his website very often. That's why there's no whistles on there. I have a low D, which is fantastic, and I've been lucky enough to have recorded with it recently - it sounds even better than I thought. Other Grinter players include Paul O'Shaughnessy, Mike Katz, and I think John McCusker. His whistles are made of wood and take a bit of looking after - pretty fragile - but the craftsmanship and his experience as a flute maker mean the tone is spot-on. I would honestly recommend Mike's whistles to anyone who is serious about playing. a.w.
