What We Think

We are really impressed with this 3.5 from McPherson. The body size itself allows the guitar to react a little bit quicker than the deeper versions without sacrificing much volume at all. The Engelmann top provides a ton of warmth and complexity. Combine that with the mellowness of Walnut on the back and sides and you've got a wonderful guitar. The setup and feel is absolutely perfect as it is on all of the McPherson guitars. This guitar is great for fingerstyle or flatpicking as demonstrated in our video. Don't hesitate to call us if you have any questions about any of our McPherson guitar inventory.

Manufacturer's Description from McPherson

Top: Engelmann Spruce 

Back and Sides: Flamed Walnut


Engelmann Spruce is light in color with rich, complex tone. This wood best suits a more gentle touch. Great for fingerpicking with warm bass and complex overtones.

Flamed Claro Walnut has a strong fundamental, with warmth and balance. Walnut has less depth and projection than rosewood and slightly darker tone than Mahogany.

About Manufacturer

The acoustic guitar is an instrument with a lot of history. Some of the most incredible acoustic instruments were made in America during what is known as the “Golden Era” of guitar building, but not much has changed since. Many boutique builders pride themselves on making the most faithful recreations of these aging instruments, and most of the focus is placed on looking into the past.  McPherson Guitars is not one of these brands.

Believing that there is more to strive for out of flat-top acoustics, McPherson introduced their revolutionary Offset Soundhole Technology over three decades ago. This allows for greater vibration in the center of the guitar top, as well as more volume and clarity in the ears of the player. Their unique bracing system also creates a larger, more even space for the top to vibrate, increasing the clarity and projection of sound. Every McPherson guitar features a cantilevered neck, which means that the fretboard does not actually make contact with the guitar top. This design allows the space underneath the fretboard to vibrate, again contributing to a larger area of flexible surface on the top. McPherson guitars also offer an enormous selection of tonewoods, from the classic Spruce, Rosewood, and Mahogany varieties to the rare and exotic. Some of the less common tonewoods like Acacia, Cocobolo, Walnut, Pau Rosa, Macassar Ebony, and others can be combined in interested ways to make very unique sounding instruments. While many of the advancements McPherson has made in acoustic guitar building result in superior tone, sustain, and resonance, McPhersons are also far less susceptible to damage than their “Golden Era” counterparts. Every McPherson neck is fitted with a carbon graphite truss rod in a triangulated system that is so stable that it eliminates the need for neck adjustment. If you are looking for an acoustic guitar that is more than just a replica, look no further than McPherson Guitars. In 50 years, they might be the ones being replicated.
