my guitar is also 17" and 43" long-2 and 7/8 deep-i just measured it to be sure in responding to you
i can tell you first hand, as i have two styles of cases, one a TKL for an L5 is great and deluxe.
And one in silver fibreglass by , i think, Musicians Gear-(looks like a silver molded cello case) -very lightwieght and has strap points, seemingly strong-both fit and protect well-the silver is significantly lighter
as i had the silver i recently bought the TKL -a wes montgomery on Guitar center close out-
i still own both
- simply because i prefer the black of the TKL, and the way the lid handles, and the way the case itself, while a good deal heavier, lies flatter and stands in the corner better, because everything is a plane rather than the swoopy molded curves
the molded one would be great for travel-but unknown if it would withstand the airlines-but its a good snug fit and prevents any movement inside the case-has a tiny accessorie pocket though,compared to the TKL
since the TKL is multi-ply lam wood-i assume it will be stronger for those odd angled knocks |
