You can get everything from sound systems, porta studios, brass and reed instruments, pianos and motorcycles that are branded "Yamaha", but the topic of this thread is "Ever played a Yamaha GUITAR?"

My ex wife had an FG180 which was inherited by one of my sons. My other son owns a better quality Yamaha, as does one of my brothers. My wife's first guitar was an LG75, which we now have strung up in Nashville tuning. These are all quite playable guitars with satisfactory tone. None of us use these as our primary instruments, but they work fine.

HuwG said in his original post that the Yamaha was "on the scale of a D-45". While Yamahas are about the size of a Martin dreadnought, they have a unique shape that is different from the dreadnought. If you place any Martin Dreadnought, D-18, D-21, D28, D-42... back to back, they will match exactly. If you try a square shoulder Gibson like the Hummingbird, it will match exactly. a dreadnought shaped Guild matches as does a Goya M-26. The Yamaha is quite different, although many refer to it as a dreadnought shape, it is unique.
