Genius invention or crazy person?

It's basically this, with a wood clamp instead of a needle.

Same principle as the Stroh violin:


I vote genius.
 
Ordered this for $2.48. Won't arrive till some time in January but it'll be interesting to see what kind of sound I get from it.

In theory I should be able to get somewhere close to the sound in the OP video. The cone is simply amplifying the vibrations of the headstock and the clip on should do something similar although being so cheap it may lose a lot of frequencies. We'll see, and i'm only out less than a cup of coffee.

Keep us posted
 
I actually think it's a pretty nice sound he's getting. Clever - even if an acoustic resonator is not exactly a new concept as others here have pointed out. Definitely for studio use most times however. Live there would be problems. Because in addition to picking up the sound of the bass, I'm guessing that cone would also tend to capture all the ambient sounds in the room. Like when you cup your ears.

Price is certainly low enough to get one just to try it out.

Reminds me of an early headphone "amp" i had.

It was a stethoscope with a long tube and a clamp to hold a modified chest piece against you headstock.
 
In the sixties a friend gave me a stethascope. I promptly taped it to my electric bass body. I had "invented' the silent headphone monitor. I knew that it was a great practice device then and thought " I should market this and make a million dollars" yea ....never did it. And then a few years ago I see that someone brought it to market. Same deal with my fishing pole, in the 70's tied a lure without a hook and went "cat fishing" in the back yard. I could cast to the back fence and the cats would chase it till they fell down from exhaustion. Now they sell the same thing in pet stores. Don't know if the "inventors" of these things are getting rich. I do know I'm still a starving artist.

I had one of those too, except the you didn't clamp the "chest end" of it to the bass. It was a suction cup.

I can't remember where I got it from but I completely lost track of where it went until about two weeks ago. We cleared out a spare bedroom to paint it and the "amp" was buried in the closet. I hadn't seen it for several years but I wish I could remember where I got it from.
 
This device looks like it would be useful in evaluating the acoustic properties of a bass guitar. You can place the body against your ear but this takes it to another level.

An important question is, how linear is it? That is, does it amplify all the frequencies evenly? I suspect that there are some dips and peaks that it might not be a big deal. Playing style can compensate if necessary.

Wouldn't know till you tried it but at $29 Canadian ($22 USD) it isn't a big gamble.
