Isaac mentioned he'd like to see a double blind side-vent test to see what affect side vents might have on tone.
I already did the double-blind test several years ago. Can somebody please repost these as links for me? This is a side vent test on a Prewar Seydel Bandmaster, key of G and a Marine Band. On one of these takes I am closing the bottom vents only with fingers. My fingers come down from the above and don't ever get in front of the harmonica. On the Bandmaster one with the block/unblock I could only close the two bottom sidevents. I couldn't close all four at the same time because I would have needed more hands than I have.
I am moving my fingers in the same way on both these samples. On one, I cover the vents, on the other, i just kind of get them near the vents, but don't block.
On the manipulated one, I can hear two distinct tones. One is constant, one goes in and out.
You can also get an idea of how the effectiveness of the two side vents compare. I've already said the Seydel was more potent, so I've spoiled the objectivity of that I suppose, but I think it's extremely obvious.
Edited to say:

SPOILER ALERT! DO NOT READ THIS POST IF YOU DO NOT WANT TO BE SWAYED BY MY OPINIONS!!!!
Okay, I heard a definite change in tone on the second bandmaster sample, and the second marine band sample. The tonal change was waaay more apparent on the bandmaster sample than the marine band... By moving his finger on and off the the vent, it sounded almost like tremolo or vibrato.
Thanks for doing this Dave! I can really hear what's going on now, and am not second-guessing myself about whether or not I really heard something! I heard it fo' sho'!

You are welcome. Now you know why I like Prewar Seydel Bandmasters so well.

Interesting.....when Seydel sent me a Noble to try I did not look at it other than a cursory glance and then proceeded to play it. I was immediately struck by how much louder it seemed to me than a Classic or Silver. That's when I noticed it had side vents. I tend to use Noble's for my low pitched instruments (low Bb up through Low F#) to help with the projection. The cover plates play a huge part in how any harmonica sounds.

You know, if touching the coverplates were what was making the difference - and I think it's a real stretch to say it is - then the amount of difference in tone should be the same on the Marine Band and the Bandmaster. The main difference between the bandmaster and MB is size of vent. Bandmaster is bigger.
