I think it may well depend, guest, on what you like as well as what you do. These particular Yamahas are expensive and the reviews differ. I like the dreadnought bass boom, and I find that cutaways are often short on that department, unless one is going to pay ten times more for Lowden.

If you play mostly unplugged, I think you may well find that this guitar will not suit you.

It will however undoubtedly mellow with several months thrashing, although the question is "how much?" and if the Yamaha specs do not prohibit it you might care to try 13-56 or 13-58 strings like we all used to play. You might also try getting your guitar fettler to raise the bass side action to 2.7 mm in stead of the factory 2.3. I like Elixir Nanowebs both for sound and durability (but they don't come in 12-58 so mostly I play 12-56s in that brand).

It is a personal choice. Two friends of mine have gone for the top of the range Seagull - both certainly are loud, very loud, one more so than the other, but I find them a bit brash. Maybe they will mellow.
