Is there a Sound Difference Between Square and Slope Shoulder Dreadnoughts

[William2]

I was wondering if these two body shapes have a certain sound like more midrange or treble differences. I have one of each, but they aren't from the same makers. And while we are on the subject, does a jumbo instrument with its narrower waist have a more articulate sound than a dreadnought?

My best guess is that any tonal difference between a slope-shouldered dreadnaught and the square variant must be negligible.
I  say this because the upper bout does not resonate anywhere near to the degree as the lower bout. This I have seen myself by virtue of an audio spectrum analyzer.

And while I haven't personally A/Bd them side-by-side, I have conducted a few same make & model, with the only difference being full body vs cutaway, and I could not hear any difference. Of course YMMV.

I am more drawn to the aesthetic appearance of the slope-shouldered style.
Likewise to the aesthetics of the jumbo body compared to the dread. But that's just me.
Judging from the sales numbers, I can only assume that my personal preference for the jumbo makes me something of an outlier in this regard.

The shoulders themselves don't do a lot to the sound, but they are referenced as two different types of dreads because they indicated differences in production, historically speaking. These days, you can find the same build with both types of upper-bout and, in that case, the cosmetic considerations are probably more important than the sonic ones.

I was watching a review on Alamo Music today of the new Gold Label 510 square shoulder Dreadnaught. They compared it to the new Gold Label Grand Pacifica 517. After playing both, they assigned sonic characteristics to each. I didn't hear much difference but was wonder if shape mattered.
