Nomad, I was wondering there were any Grand Symphony or Dreadnought models at your local dealer made of similar woods that could be compared to the Grand Orchestras ?
The 510ce & 516ce have Engelmann spruce tops standard, rather than Sitka, but the 610ce and 616ce are close to the 618e, as well as the 910ce and 916ce, other than the bracing pattern with Adirondack spruce and the side bracing.
I've heard the GO described as a big GS and just another Taylor.
From that description, I think the Grand Orchestra would be a great line of guitars.
They don't carry a lot of Dreadnaughts. There was a 310ce which, given the similarities of Mahogany and Sapele, is close enough.
To my ears, the GO had a rich, almost "gooey" bass quality that the 310ce didn't have. "Gooey" probably isn't the right word to use, but it was just so luscious that it really does describe it pretty well. It's not so much a description of the sound, but rather how the sound makes you feel. The bass from the 518e was deeper, richer and more distinct. The same could be said for a comparison to the 316ce they had.
The dealer got hit pretty hard over the holidays, and they sold a
lot of Taylors. They were waiting for the NAMM Show to order stock, so I was only able really to compare the 518e to anything.
