Default Same Model - Different Weight?

I have 2 Epi 339s, one '12 w/HB and one '16 w/P90. Epi says both have the same features/design, laminated maple bodies/tops, same hardware other than pickups, necks feel the same size/shape.

But, the '12 weighs .8 pound more than the '16 (7.4 v. 6.6 on a good digital scale). I get that no two guitars will weigh the same due to variations in wood used, etc., which is why manufacturers don't typically list weight, but almost a full pound? That seems like a lot, it's a high percentage of the total weights we're talking, and I wonder if anyone has any Epi-knowledge of what could account for the sizable difference.

Also interesting is how different even 12-13 oz feels when you pick up the guitar. It's really noticeable.

Are they made in the same plant?

And I have seen variations in the range of + or - 200 gr. on electric guitars.

I can't find any plant markers. As for your observed range of variation, isn't 200 gr. equal to 1/2 ounce or so? That would make more sense than the 12-13 oz I'm seeing between these.

I see others have had the same question, and the differences are more pronounced with solid body guitars, so I should have mentioned that the 339s are semi-hollow, with a center block.

With any species of wood there can be significant differences in density, even in the same species, same tree, and same board.

454 gr. is approximately equal to 1 pound, so 200 gr. -

That's only a 12% difference, could easily be due to different wood densities, even if they are the same species.

Again with the math! I'm surprised to learn there could be such a percentage difference in weight due to same-wood composition, when the design/dimensions/hardware are the same, and the overall size relatively small, but there really can be no other explanation, assuming Epi's correct about using lam maple for both guitars.

I could more easily see such a difference between Gibson's 339 and the Epi, with the Epi the heavier of the 2, due to more individual wood pieces for the top/back, consequent glue, and perhaps an added veneer to visually unify the frankenwood pieces. The Gibson version's weights I've seen are 7-7.2 pds, but it wasn't clear which of the 2 offered necks (heavier '50s or lighter 30/60) was in place.

I've got two Gibson Les Pauls, a '74 that weighs 9.8 lbs and a 2018 that weighs 7.8 lbs. Now, the 2018 IS weight-relieved, with a system of eliptical cavities routed into the body.

Is there any chance that one of the two guitars is weight relieved? And yes, the difference in weight between the two guitars is profound. Both sound great. I've played the '74 since '77 and it has grown rather fullsome to carry for a two hour gig or a long session as I've, ummm... matured.

Very good example of how to ruin a Les Paul...ok my Classic has the swiss cheese to same abotu 250gr, but that's massive.

In terms of weight I know Gibson select the mahogany backs, the lightest non relieved go into the 1959-1960 reissue, the heavier into the Customs as the Custom has a reputation of being an heavier sounding guitar, in that case the difference might be about 500 gr.

Norlin Les Pauls were even heavier than 4.5 kg, Yamahas SG2000 from the 70s were above 4.5 and generally heavier than LPs (they had more maple), SG3000s from the early 80s might get to 4.7 kg, mine which is from 2009 is "lightweight", 4.45 kg. My 2009 SG2000 in comparison is 4.25, and I can feel the difference on the shoulder and in the sound.

Nothing I've seen in Epi lore suggests that possibility. The 339 is already a semi-hollow (2 empty chambers with a center block, and F holes), and both look the same through the holes. I suppose it'd be possible to lighten the center block some, but not the case here.

I should add that the heavier of my 339s is part of a limited "Black Royale" run that has a little metalflake in the paint, as well as a double sparkle binding on body and neck (oh yeah, it's pimped), while the lighter one's less sparkly. It's possible something about that Black Royale finish and accoutrement adds a bit to the heavier one's number.

If they were made in different plants it might be possible one had a mahogany block and the other maple.

That size piece would certainly get to the difference here. Gibson specs maple for their 339 block, while Epi specs "solid center block."

I have owned a few guitars/basses that were the same model and same woods. Weight varied, as did the tone.

It's pretty common. Not in Epi specifically, but in general. I have a Tele that's super light and comfy, and another one that I could use to drive railroad spikes. And they sound just about the same.
