i just received an email, containing the secret to the mysterious tremolo.
there is a partition between the bellows and the reeds. in that partition is a little trapdoor, a bit like the one you have in your backdoor to let the cat in and out
at the bottom ,there were the trapdoor moves freely, there`s a little weight that makes it fall back.
So when you start playing ,the little door starts waving.
At one point the door is shut so you hear no sound, when it opens again there`s sound.
when you speed it up, like when your playing a tune it sounds like this:
sound - no sound - sound - no sound etc.
i had to translate this so i hope you get the point
I sure wish we could see the inside of that thing. I am trying to figure out how the trap door thing would work just as well on the pull as on the push. Any ideas?
Also, how does air pass normally through the partition without tremolo? Are there holes in the partition normally (non-tremolo) and you pull the trap door thing into place for a tremolo?
From the description of it being like one of those cat doors, it sounds like it swings open in both directions, one way on the push and the other on the pull. That's the picture I get anyway.
the trapdoor moves to both sides of the partition, so when you pull you suck the door into the bellows, and when you push, you blow it towards the reeds, that is probably the reason why the bellowbox on the treble side is deeper. The little weight attached, makes the trapdoor fall back at a certain point, when it falls it falls back through to the other side, because of the weight the door keeps swinging back and forth.
it`s realy best compared to a catdoor, it moves to both sides through the door......
Man i have a hard time trying to explain this
as for the sound...you all must have heard a hammond organ with a Lesley speakerbox attached.
it makes soundwaves by covering the actual speaker at a certain pase, it`s the same effect: sound - no sound.
When i meet the guy with the instrument il will ask some more questions, Ron will be there also, so he can help me
