Most experienced players will tell you that there's almost always always a direct relationship between the weight of a guitar and it's volume and tone. For fun, I weighed a number of guitars in the DjangoBooks inventory to see how this panned out. The results were more or less what I expected...the guitars that have the best tone and projection are also the lightest.
Here's the data:
1) Jean-Pierre 1990 Favino 14 Fret D Hole
: 4.00 lbs
2) ALD GRANDE BOUCHE 14 FRET
3) Dupont Vielle Reserve: 4.15 lbs
4) DELL'ARTE D-HOLE HOMMAGE
: 4.45 lbs
5) Saga Gitane DG-340
: 4.8 lbs
As expected, the European guitars had the lowest weight and also the most outstanding tone and projection. The Favino and the ALD are very closely matched for sound quality...both being outstanding instruments and also very light weight. In general, I've found most Asian copies to be much heavier...and in this test that proved to be true.
It's interesting that the JP Favino is the lightest because it has the large Favino body proportions. So if you take the larger size of the instrument into account, it's even lighter! No wonder it sounds so good...
Both the Favino and Dupont have DR tuners which are probably a lot heavier then standard tuners. So both of those instruments are actually even lighter in comparison.
Just for fun I also weighed an archtop, which is light for an archtop, and it weighed 5.1 lb. I used to have a Gibson archtop and man, that thing was heavy!!
I also have a Martin D28 flatop which was 5lbs. Interesting that the Sagas are closer in weight to flatop and archtops then Selmers.
