I just got Syn whistle and i have to say i really fell in love with this whistle. for an inexspensive whistle its really really good.
i bought a set and has exchangable keys D, C, Eb
the first octave on the whistles are nice and smooth / warm sounding and the second octave is nice loud and crisp.
i love these whistles
It’s nice to find a whistle that ya love! Give it a real workout every day!
Yes, I agree. They are very nice whistles. I got the complete set (from A to E) several years ago and haven’t bought another whistle since. My WHOA is completely under control . . . for now.
I got the whole set too and I’m very pleased with it. I bought a dixon trad and a dixon tunable aluminium both in D because I heard some good things about them, but still I like my Syn the best. I bought it because I didn’t had any good D whistle and I also wanted some other keys (WHOA 
) and I read some things about this set and desided to buy one, the complete set is cheaper then a good high end D, but for me these are just perfect.
It’s very good posible that I’ll discover another whistle one day that will I like even better then the Syn, but for now, the Syn’s are my favorites.
I love mine. I have the Eb through Bb. All have a great sound.
Got a Syn whistle set (Eb,D,C and Bb) for Christmas and I REALLY like it alot. The bell note is nice and solid. The tone is bright and the fit and finish are good. Haven’t had a chance to play anything but the D but hope to be able to tackel the rest of the keys this week.
Several YEARS! Your WHOA really IS under control!
