Hi all,
I had the pleasure of trying the new "Pro-Mellow" and the "Pro-Plus" whistles yesterday. It's really great living only 15 minutes away from the Sweets.
You can read all about them now, on the Sweetheart website. The woodgrain is pretty and they are very lightweight. The transition from first to second octave is nice and smooth, and the second octave is sweet, not shrill. The "Pro-Mellow" is a little quieter than the "Pro-Plus". Being more quiet, I found the tonic note to be sensitive, and I overblew it easily, but I tend to do that on quiet whistles. Someone else may do fine with it. It could even be just getting used to a new whistle, and how to treat it. Being a little louder, the "Pro-Plus"' tonic note is nice and solid, my preference. I have an older "Sweetheart Killourhy" whistle in Blackwood, which is loud in the second octave, so I thought I'd like the "Pro-Mellow", but I loved the "Pro-Plus" best. The volume was about the same as the Killourhy, but the second octave was much more focused and sweet.
Don't forget that I am only describing my experience with them. Someone else could have a different experience. So, to know any more about them, I guess you'll just have to get one, or try one, if you're fortunate enough, (thank you Ralph and Joseph for the opportunity) and see for yourself.
