Ian lamb low D ?

Hi! I receive my first low D whistle, it’s a Ian Lamb.
I would like to know if someones have comments about that maker and is product.

I’m not a (pro) on the whistle but i don’t realy have problem with the tin whistle. What i like to know if it is normal to have difficulty to obtain a good low D on the low whistle, i mean , i can make it sound pretty much ok but i’m not able to obtain enough volume, that’s almost a wispering!!
Since i received that whistle that low D became better but i always have that problem of volume. If i tried to blow a litle bit harder the sound become like a wave.

So, ok it’s probably just me but, if it’s not, do you have some tips to resolve that?

I think you intended to post this to the whistle forum – this is the flute forum.

That said, my experience is that a weak bell note in a low whistle either indicates poor design or some flaw in the construction. I had a Water Weasel low-F that was very weak at the bottom, sent it back to Glenn, and he tweaked it and improved it considerably. Some low whistles just have weak bottoms consistently. Don’t know about Ian Lambes, though.
