Ovangkol has a similar tonal range as Rosewood, but the midrange is 'boosted' rather than 'scooped.' So the 410 should definitely have a noticeable sonic distinction from your 810.
I personally prefer Ovangkol to East Indian Rosewood (like in your 810), but not as much as some of the brighter-sounding woods (e.g., Cocobolo, Koa, Maple).
Hi Tim,
I actually have Martin D-18 (solid spruce top over solid mahogany back and sides) and not a 810. I was using the 810 (Rosewood) as a reference to what I had read about the sound of the 410 (Ovangkol). How about comparing the 410 to the D-18? Any thoughts?
Thanks,
Rob
Sorry, Rob; I didn't read your post closely enough.
I personally have only played one Martin guitar; it was Spruce over Mahogany, but I'm not certain it was a D-18. I was comparing it to the Taylor 510 (also Spruce over Mahogany), and for all intents and purposes, they were sonically equivalent to my ears. So let's assume for the moment that your D-18 and my 510ce are similar enough in tone to qualify my 510ce as an analog for your D-18.
I've not directly compared a 410 to a 510; but I suspect that they would be largely similar in tonal profile. Both Mahogany and Ovangkol project 'boosted' midrange frequencies, with Mahogany favoring a bit more of the high end and Ovangkol being a bit 'warmer' to my ears. I think the primary difference would be in their overall tonal ranges; Ovangkol has a much wider response range (both toward high and low ends -- hence the reason it is often compared with Rosewood), whereas Mahogany tends to 'live' in the midrange frequencies. I also don't generally find Ovangkol to have the clarity of Rosewood (or even Mahogany), which is one of the properties that I do like about that tonewood.
I think you could hear some differences in tone between a 410 and your D-18, but whether those differences would be different
enough to satisfy you is a bit harder to pin down; it's a pretty subjective topic... I suspect that a Rosewood guitar -- as opposed to Ovangkol -- would really be closer to what you're wanting... But your budgetary considerations seem to be pushing you away from an 810... Have you considered a used 810...? Or, if you're a fan of bright-sounding guitars, a 'legacy' 610? That would definitely be different from your D-18.
Regarding the Grand Auditorium (GA) compared to the Taylor Dreadnought (DN): Both are similar in size, but the DN shape promotes the midrange frequencies, whereas the GA seems to provide a more even overall tonal balance. So a 514 might strike you as quite different from your D-18, even though they both have solid Mahogany bodies. If you can try out a 514, it wouldn't hurt to consider it.
