I just played a new Sindt d at our monthly gig last night, me and a guitar, no sound system, and wanted to say that it was the first time that I felt comfortable enough to let go and play a high whistle.
I’ve got a sweet Glenn Shultz whistle but it tends to clog. I’ve got a nice-sounding Shaw, but the intonation… And I’ve got a variety of other cheaper whistles. But the Sindt played wonderfully for several sets of tunes and the guitar player enjoyed it as well.
Thanks John,
Michael
In my experience, once people play a Sindt they rarely switch. It’s great once the Sindts take over your local session, because all the whistles are in tune with each other!
I have one of these with a delrin head and a silver tube.
Really a good whistle.
You can send that one to me. I’ll take care of it! 
I like the Sindt as well. John makes a nice whistle.

Get the metal head ferrule of the Schultz nice and warm before you play it (NOT by breathing through it: warm it with your hands) and it shouldn’t really clog much. Also, the soapy water trick helps a lot.
