Official Luthiers Forum!

I ran across this in a guitar site linked to an artist posting. I see all kinds of problems with the concept and, likely, this guy has more of an artist understanding than luthiers.

He calls it a Multi Chamber guitar. The concept is an individual bridge to each individual chamber so one could tune each string seperately. or thus goes the theory. It allows even different materials to be used at the same time as long as they fit the mounted chamber format.

I don't think this guitar exists but is a photoshoped workup. As it's interesting, I thought I'd post it here so you OLFsters can have a gander.

Acoustically it will never work very well .. you cant drive a top from that bridge location with any effectiveness ... look at the A string, the top is about as stiff as can be where the string/bridge attaches, and then the top area is pretty small fro driving that frequency, no matter how well you tune it. My guess is even an Ovation would sound better

Artistic, sure .... but we were supposed to have flying cars by 2000

Besides the fact that it probably wouldn't work well...I don't think its very attractive at all.

This is very similar to what you see with very high-end speakers, separate, tuned chambers for dedicated acoustic response. This implementation of the idea won't won't work very well though as Coach Tony pointed out.

Oh no................

Since I am now officially a guest and can't see the pictures of this guitar, I can only guess at this reinvention of the wheel.

The basic problem is that the single big chamber of an an acoustic guitar is barely large enough as it is to support the fundamentals of the lowest notes. Any attempt at making even smaller chambers is doomed to failure, not by me, but by the laws of physics. This thing keeps coming up in the solid body guitar world where luthiers imagine that they have made multiple tuned chambers in their guitars. It's a crock of wishful thinking.

Rick, post in the problems logging on thread. Also, some have had some luck using <Control Panel> <Internet Options> <Delete Cookies> and try again.

Nahhh...

I think I'll just go to Tasmania next week, stay off line for a while, and come back and register under an assumed name like so many other folks here. Then I can be my usual feisty self, and nobody will know who I am... It must be fun to be able to say stupid or nasty things and not be held responsible for them...

'til I get back, I'm happy to be a guest.

Signing with his real name...

Not a big fan of modern art, huhn Sam?

I see basically a big misunderstanding of how a guitar works or at least in realationship to what I understand. The losses of energy through the bridge alone would be substantial. It looks aluminum, by concept, which of course would resonate without offering much output of sound itself. The "light and rigid" ideal isn't addressed well by this.

Without the rigidity one has a.... banjo! Without the light soundboard one just has a thud! I like looking at it for the lateral thinking and it has given me some other ideas but no, I'm pretty sure it would sound bad!

Yeah! and where is my flying car! Popular science promised flying cars by 2000!

*sigh*

I love the saying, "If it ain't broke, don't fix it"..............looks like something that Eccentrica Gallumbits might try and play to impress the lads, but in reality?

Yeah, great concept, I'll try and design the same with a 42-string Linda Manzer Picasso guitar....

i actually really like the look a a lot. It's a cool design but i don't think that it would work very well. I'd defiantly go for it if it was an electric, that would be SWEET.

That bridge/saddle arrangement is actually a hydroacoustic coupling devise. The top is actually drive by a hydraulic pumps with input from the bridge and series of pulleys and levers that drive the top, these are hidden inside each chamber. It's an amazing device!

Got give em credit for thinking out of the box.
