Re: Sound holes in Ribs. Do they work?
I had red a review on a Condino mandolin once that had 3 side ports that could be left open or blocked off in 3 different configurations. I located the review from JazzMando.com on his green "Cricket" mandolin. Here's a excerpt from that review.
"We mentioned the three-hole design on the face, but let's look at his "mirror" of the three holes on the side. Side ports can be a bit problematic in that the sound that comes gushing out of the top to the audience likely won't be the same sound to the player; not better, not worse, just different. Another problem is the way it affects the aperture of the air in the chamber, we found a striking difference in the tone of both instruments when the side holes were covered. James offers custom-made plugs for his instruments, and we would likely opt for this, as it boosts the bass significantly, and adds a dimension of richness to the bottom end. That said, we found you can vary the amount of hole-covering by blocking only one or two of the ports, very much like adjusting individual bands of EQ on your stereo. Practical? We might never use this, but a musician with more creativity might unravel a whole new world of tone variety, right within the same instrument!"
