Got this beauty a week ago. It was used but in perfect condition and came with a real good softcase. It has solid woods, sitkaspruce for the top and mahagony for the back and sides (therefore the M in the title). It also has got a passive pickupsystem, so there are no knobs and battery in the guitar. You need a good pa with enough gain or an acoustic preamp. No problem for me because I own such a preamp. The chinese built Yamaha is perfectly built and plays like butter. It sounds rich, full, warm and round with strong bass, present mids and mild highs. I would say it´s close to a J45 which is a good reference and not as mighty and loud as a dreadnought. Real nice guitar for affordable money.
