My next basswhistle is almost completed:
It’s a Low-Low-D. An octave below a low-D whistle.
This one uses a stack rod system much like the Boehm flute, currently it has six holes and extra key will eventually go on it for flats/sharps to make it chromatic.
This time, I bent the mouthpiece around like a bass flute to make it more compact and easier to hold.
I’ll put up a better picture when I get access to a better camera.

That is soooo cool

I wounder how that beast sounds…
Here’s a rough wav file of it playing a few notes. You might need to open it with media player.

Well, it’s low alright! What sort of fipple design did you use for that whistle??
1 1/2" Sched. 40 PVC, same fipple design as my PVC whistles. Only I used a piece of walnut (some large lying around the shop) to make the block. I need to replace it eventually with sometime more suited for fipple material.
It’s actually easier to build fipples for something this big and the macro scale of it kind of teaches you more about voicing whistles.
wow, I agree with the statements of lowness. Sounds very soft (no surprise) but also sounds very breathy in its tone… is that just a relic from the recording process or part of the actual sound
Okay, on second listen I think you may have just answered my ruminations upon how a whistle would sound through a distortion pedal (and hopefully I cause no offense with that comment)
A cheap computer microphone sitting on a plywood table. It’s not a pristine recording condition.
The upper register is a bit airy, I hope to improve it by changing the block to a better material and do some finer voicing work on it.
fires up Cool Edit and tries that
It kind of does sound that way, with all the popping. Also takes the breathiness right out of the Clarke Original, and turns it into one of those odd high guitar shrieks from 80s power rock. I would post a sound clip, but I don’t have any web hosting for it.
Neat! But I wouldn’t play that near a herd of Elephants, knowing that they communicate at a level humans can’t hear (subsonic? supersonic?) You might not want to find out

Elephant 1: “hey Clide, Isn’t that guy the schmuck that was whacking you with a stick last week?”
elephant 2: “Yeah Bob I think your right, Whos that guy with him? I’m going to charge them and see who runs first.”
Elephant 1: “Sounds like a good idea, I was just going to hose them off with some snot-water.”
Cutting-edge stuff as usual, Daniel. 
That’s way cool.
