Not exactly answering your question, but I have a small number of Yamaha cheaper guitars on the basis of what you are saying. A laminated ply top for club work was a bit better for throwing around. (Had an old Yamaha thirty years ago, can't remember the model but less than £100.00 out of CV Berry in Worksop at the time that had a pint poured in it and a hole in the top where a mic stand end pushed through it. Still sounded good enough for club work.)

This is an interesting guitar. The best quality Yamaha I own these days is a APX, and the LLX seems on paper to have the advantages c/w a bigger body, better wood and up to date technology.

The ART is of less interest, as if I am plugged up, I tend to use my trusty Rainsong with the LR Baggs gear. The ART will be state of the art as it were, but as ever, it depends on what you plug it into as far as the end result is concerned...

In general, with CNC profiling, accurate measuring and quality control of timber seasoning, computer modelling of vibration and stiffening, decent glues etc., the cheaper makes are for me better than the mid range makes of twenty years ago. Once you get the action etc set up correctly, (add £25.00 or so for a good job) I am convinced guitars are down to taste as much as quality now. The guitar in question has to be good...
