MG 4.5 Flamed Koa & Koa

Sale price$13,900.00

The all koa McPherson 4.5 delivers a uniquely focused voice wrapped in striking, organic beauty. Built entirely from koa for the top, back, and sides, it offers a tonal profile that is immediately articulate - clear and present in the mids, with a smooth, controlled low end and a sweet, chime-like top that never becomes brittle.

Visually, Koa brings a natural depth and chatoyance that shifts in the light, ranging from golden honey to deep amber and chocolate hues. It’s a build that feels as much like a piece of art as it does an instrument.

Tonally, the all koa construction leans toward clarity and balance over raw power, with exceptional note separation and a quick, responsive attack. As it opens up, the voice develops added warmth and harmonic complexity, giving it a refined, “played-in” character while retaining that signature koa sparkle.

Product video

OFFSET SOUND HOLE

Driven by the belief that traditional acoustics could be reimagined, Matt McPherson developed the groundbreaking Offset Soundhole. By positioning the soundhole off-center, the central part of the guitar's soundboard remains longer and uninterrupted, enhancing vibration across the top. The result is greater volume, clarity, and a richer sonic experience for the player.

CANTILEVERED NECK

Every McPherson guitar features a Cantilevered Neck, which is not glued or connected to the top of the guitar, but instead floats above the soundboard. This design allows the soundboard area underneath the fretboard to vibrate freely, which increases the sustain of the guitar.

OVERPASS / UNDERPASS BRACING

McPherson’s unique Overpass/Underpass Bracing System creates a larger, more even space for the top to vibrate. The soundboard’s braces cross each other but never touch or inhibit vibration. This frees the braces to vibrate independently while still lending structural support and maximizing soundboard vibration.

CARBON REINFORCED NECK

The McPherson Carbon Reinforced Neck is praised for its incredible strength and stability and is built around the largest carbon fiber truss rod ever used on a guitar. Attached to the body with a triangulated heel design, it stabilizes the neck and virtually eliminates the need for neck adjustments.
