Body and Construction

This popular dreadnought-style body has a very warm yet rich tone. It’s a result of the solid spruce top and mahogany back and sides. The new scalloped bracing adds rigidity to the spruce top. It provides a full and present performance.

The traditional western body cutaway gives the acoustic a classic look. But it’s the A.R.E. (Yamaha’s high heat treatment) that gives this guitar it is a beautiful color.

On the back side, the mahogany and binding look great and are finished to perfection. The back and sides on the A3M, made also from mahogany, also contribute to the thick overtones of this guitar.

Neck and Headstock

The neck on the A3M is made of mahogany with a straight taper. The fretboard is rosewood with hand-rolled edges, 20 frets, and a 25.5-inch scale length.

The neck has great string spacing and a nut width of 1.7 inches. This makes for a very comfortable and easy-to-play guitar. Especially with the standard diameter neck shape. The headstock on the A3M is the signature Yamaha-looking shape that is found on most of their guitars.

The Yamaha A3M uses a Urea nut and saddle as well as PVC bridge pins as stock parts on this guitar. The chrome-plated tuners were smooth and functioned without any tightness. They held tune well and did not let up when we truly dug in and played hard.

The A3M also comes with Yamaha’s own S.R.T.2 (Studio Response Technology) system. This is a combination of a piezo pickup and a microphone. The pre-amp is controlled with a master volume control as well as a 3-band EQ (Treble, middle, and bass).

Sound Performance

The A3M is an amazing sounding acoustic! The guitar is solid wood and has that well-balanced rich tone to it.

But it is very bold and has a stunning sound projection. This is still very articulate thanks to the solid spruce top.

The SRT2 electronic system really captures the rich sound of the acoustic and is dynamic. The EQ responds great, providing a good range of control. It just might be one of the best pickup systems we have heard of at this price point.

It is a great feeling acoustic for sure! The action was nice, the guitar almost feels like an electric model. It’s easy to play all the way up the neck, thanks as well to the cutaway.

The string spacing and neck thickness were right on, it’s definitely easy to play. It is easy to give the Yamaha A3M a good review when it feels like this.

Yamaha At NAMM

Yamaha can be found at NAMM each year and always brings some great guitars among other things. I always enjoy visiting their booth to see what they have cooking.

I find that the A series guitars are always a big hit, and it is no wonder.

One of the reasons we choose the A3M to be part of our recommended guitars is because they are a hit with players! So if you are a beginner, rest assured this is one great guitar!

Final Thoughts

With a good deal of acoustics under 1000, it can be tough to find something that is exciting and new. The Yamaha A3M is on the higher side of the price range, but for good reason!

This guitar is really impressive and will bring you an exceptional experience. Whether at home or on stage, you will be golden utilizing the electronic system.

Yamaha is a well-known builder and has many years of making great guitars. Their “A” series guitar brings the goods. It tells of their experience in manufacturing!

This is another one of those guitars that are hard to put down. It sings when you strum and barks when you really dig in!

The spruce top and mahogany body make a killer combo. Yamaha really created a wonderful acoustic here! If you are upgrading your current guitar, you will be very happy with the A3M for years to come.

If you own some very expensive acoustics, the A3M will fit in quite well and may even be quite the contender.
