Road RunnerRRMAJBO ABS Molded Jumbo Acoustic Guitar Case - JUMBO ACOUSTIC
1/5
Independent shopping perspective
The Korena take
Molded ABS hardshell sized for jumbo acoustics — 17.1 inch lower bout, 6.25 inch body depth. For hauling a big-bodied acoustic that dreadnought cases won't hold.
Strong match
Who this is for
- Jumbo and slope-shoulder acoustics too wide for a dread case
- Acoustics that live in a van or trunk between gigs
- Damp climates where a plastic shell beats wood
Consider the trade-offs
When to look elsewhere
- Dreadnought, concert or parlor bodies — they'll slide around inside
- Bodies deeper than 6.25 inches, including most archtops
- Tight storage; it's 47 inches long and 20 wide
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
6.25 inch body depth
Deep enough for a full jumbo. Anything thicker through the rim won't let the lid close without pressure.
Detail 03
12.6 inch upper bout
Narrow up top relative to the lower bout. A guitar with wide shoulders can bind before the body seats fully.
Detail 04
44 inch interior length
Fits full-scale acoustics end to end. Measure from strap button to headstock tip, not just the scale length.
Detail 05
ABS molded shell
Sheds water and ignores humidity swings that make wood cases swell. It flexes on impact instead of denting.
Detail 06
8.25 inch exterior depth
Thick. It won't lie flat under a bed, and two of them fill a car trunk on their own.
Final check
Know before you order
- 01Measure lower bout, rim depth and total length — jumbo sizing varies a lot between makers.
- 02A dreadnought fits lengthwise but rattles sideways. Pad the gaps or size down.
- 03Case only. Humidifier, strap and strings are separate.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will a dreadnought fit in this?
It will physically fit, but a dreadnought's lower bout is narrower than 17.1 inches, so the guitar moves inside. That movement is what damages finishes on a long drive.
02Does it fit a 12-string jumbo?
Yes if the body measures within 17.1 inches across and 6.25 inches deep. Twelve-string jumbos usually share the same body as their six-string version — check the headstock length too.
03Is ABS as protective as a wood case?
Different strengths. ABS resists moisture and impact by flexing; wood resists crushing under stacked weight better. For a guitar in a car, ABS is the easier choice.
04Can I check it as airline luggage?
It is not built as a flight case. If checked, loosen the strings and pad the headstock. A hardshell like this handles baggage handling better than a bag, not perfectly.
