@SerErris My post was not a reply to you but the thread topic in general. Most dealers have pretty good return policies so perhaps you can take that route. I hope you can get your issue resolved.
I just found that blog post interesting since it discussed the issues with Walnut. It seemed that the best of the best get used to produce veneer. I’d rather have solid Walnut with some character flaws than veneer. It does seem that Sequential should change the verbiage of their advert from heartwood to the actual lumber grade.

For more information on NHLA grading and defects, be sure to check out Understanding Hardwood Lumber Grades.
FIRST AND SECONDS (FAS)
Black Walnut lumber
Above grade Walnut can be found in wide and long boards but you will pay a premium for it.
This is the highest grade, and NHLA states for all lumber the following:
83.3% clear of defect on both faces
Minimum Board Size: 6″x8′
Minimum Clear Cutting Size: 3″x7′ or 4″x5′
Now for Walnut lumber, the rules are changed, and the bar is lowered to allow a wider sample of wood into the grade. The above guidelines are the same with the exception of the following changes:
Minimum Board Size is reduced to 5″x6′ with 80% of the pack yielding 8′ and longer
Minimum Clear Cutting Size is reduced to 4″x3′ or 3″x6′
Pieces 5″ x 6-7′ are allowed wane along the edges, splits not longer than 6″ on 1 end, and 1 defect
Pieces 8″ and wider are admitted 2 defects
SELECTS
Walnut hardwood
Shorter and Narrower Boards will be more common with Walnut lumber.
This grade is very similar to FAS, but now both faces do not have to meet the grade. The standard grading rule for all species is:
83.3% clear on 1 face only with the 2nd face being of #2 Common grade
Minimum Board Size: 4″ x 6′
Minimum Clear Cutting Size is the same as FAS but for 1 face
For Walnut, again the rules are changed as follows:
Minimum Clear Cutting Size: 4″ x 3′ or 3″ x 6′
Essentially, the rules for Selects Walnut are the same as FAS, but again only 1 face must meet the grade and the other face must meet #1 Common grade.
#1 COMMON
Walnut lumber grade
More knots means more chances for beautiful, crazy grain
The Common grades are much less in demand for most species, which is a shame, because as you will see there is still quite a bit of usable lumber in each board. Usually being able to work with and around knots will make you a great customer for Common lumber. The standard grade is:
66.6% clear on both faces
Minimum Board Size: 3″ x 4′
Minimum Clear Cutting Size: 3″ x 3′ or 4″ x 2′
For Walnut, again the guidelines are the same with the following exceptions:
Minimum Clear Cutting Size: 3″ x 2′
Again, the cutting size has been reduced, yet the percentages remain the same, which basically means smaller boards can be admitted into the grade.”
I hope you are able to resolve your issue.
The point is, they advertised it on their front page as:
The Whole Package
All of this punchy, powerful, analog goodness is housed in a full, five-octave, semi-weighted Fatar keyboard with USB, MIDI, Gate and CV ins/outs, and a premium-quality, steel and hand-oiled, sustainable black walnut heartwood body that make it as satisfying to behold as it is to hear and play.
The product shots reflect that.
Mine is on the front plate half heartwood and half sapwood. But it is in quality. So it is directly in your eyes every day.
