When bagpipes don't take their meds.

[FretlessSix]

Anyone have any idea how to make one of these?

Had Helmholtz been in charge of the air raid warnings in the 40s, WWII would have had a much more pleasant tone to it all... function and style.

[jackiAntenna]

That's amazing... Where I can buy this Helmholtz???

Thanks Martin Carlè...

[mandolin333]

Awesome.

Opportunities such as these don't come along very often in life.

An experience to remember. Bravo Bill.
