I have 2 regular bores that I love – one tuneable, one not. I’m thinking that a narrow bore would be even quieter, and therefore nice to have for traveling. I have some clogging problems with my nontuneable (which is an older whistle).
Is there enough difference between the regular and narrow bores to warrant having both? How about clogging – is it worse in the narrow bores?
Tery: I own an aluminum non-tunable Hoover set in various keys, plus an extra CPVC D, a whitecap, and a narrow-bore aluminum D. The narrow-bore D has the lowest volume level of any whistle I have ever heard. It is significantly softer than the standard bore Hoover D. Since I use the liquid soap method to prevent clogging on all my Hoovers, I have never noticed clogging on any of them.
Modulating the air flow on the narrow-bore can be a bit of a challenge at first. The whistle is very easy to overblow. When a person finally gets it right, the narrow-bore makes an inspired practice instrument, and under mic’d situations, can be used to create a very soft and gentle high end for tunes like Captain Picard’s Air, no matter how large the audience.
