The vents are regulated with the forefinger. The bottom cover is identical but non-vented.

Ivan Saric used to (maybe still does?) cut a hole in the cover of his sp20 and use it to effect I suspect rather similar as this would be.

Superbee, That's cool, it adds a bit of legitimacy to this design. I couldn't find anything specific about that on the web but I did read about Ivan using unconventional hand techniques.
I understood that includes sealing everything off then playing while releasing backward air pressure through one reed hole. It's something real easy to do on the Big Six for example. I can easily imagine Ivan exploring something similar using a hole in the cover plate.

Not really what it's for, but I played with toothpicks in the back of my harp, like they were fingers on strings... I'd slide them along the reeds to change pitch.
I got some interesting effects. No idea what it does to the durability of the harp. I even considered mounting them above through holes in the cover on a pivot for better control. To fiddly for my fingers (I'm actually heading out to get assessed for carpal tunnel in a couple minutes) but I get the impression that if someone worked on it it could be an interesting technique.

Nate, The reed lever is a very creative idea. I can imagine it would take a very delicate touch.
I sure hope things go well for you.

This is an interesting design, but I don't see what/how it is supposed to aid in playing. Volume?
Nate your idea to mess with toothpicks over the reeds made me think of a clip I saw, somewhere, where an Asian guy was running smallish magnets up and down or close to steel reeds as he played, made some odd sounds, not what you'd expect, rather otherworldly sounds. I have tried to find the clip just now, no idea where I may've seen that. I know about Seydel's adjustable "All Minor" harp, but the clip I'm referring to yielded a totally different bunch of sounds. Wish I could find it again, maybe someone of you have seen the same clip?

My favorite thing about that design, is the shape of the cover plate. It combines the Manji type cover, with a pro master type. Love the 4 through hole type screws.

I started looking at the effect of side vents. I decided to get more extreme. Yes the above harp is louder when the vents are open. There is also a change in tone. The change of tone and volume is pretty obvious when the vents are rapidly opened and closed with the forefinger.
I am a big fan of the shape of the Manji covers. The deep finger cradle also works well for easily sealing the vents.
I made another set of covers without vents. The bottom cover of that pair is threaded so the four fasteners just screw right in. That results in a totally smooth bottom cover and no more fumbling with nuts.

Thiscover design would certainly make it easier to adjust the reeds' gaps, if need be. I understand the idea now, guess it could be pretty cool, actually.
