Guild M-120 Westerly Concert Natural Mahogany Left Handed

Full Description

Compact body with rich tone

The Guild M-120 Westerly Concert Natural Mahogany Left Handed stands out for its compact concert body shape, which delivers a voice that’s both delicate and defined. This size offers a well-balanced tonal response, with clear mids and focused lows that don’t overpower. Fingerpicking feels articulate, and light strumming produces a sweet, resonant tone with excellent note separation. The smaller body ensures clarity and dynamics, making it ideal for folk, blues, or solo acoustic work. It’s a comfortable fit for long practice sessions, writing new material, or recording, all without compromising volume or projection.

All-solid African mahogany construction

Built with solid African mahogany for the top, back and sides, this guitar produces a warm, woody tone that grows richer the more you play it. The all-solid wood construction is a key feature that elevates the M-120L above many guitars in its class. Solid tonewoods resonate more freely than laminates, offering improved sustain and depth of tone. Over time, the wood naturally opens up, enhancing the guitar’s character and making each one feel personal. Combined with the classic OX bracing pattern, the mahogany delivers warmth with just the right amount of punch, perfect for those who value expressive tone.

Effortless playability and vintage neck feel

With a 24 ¾” scale length, 1¾” nut width, and a vintage C-shaped neck, the M-120L is incredibly playable right out of the box. The slightly shorter scale means reduced string tension, making bends and chord transitions feel smoother, especially during fingerstyle passages. The wider nut spacing gives your fretting hand more room to move, adding comfort and control for both beginners and seasoned guitarists. Paired with a rosewood fingerboard, medium/high frets, and a modern 16" radius, this neck brings a vintage vibe without sacrificing modern performance and feel.

Iconic Guild styling and premium details

Visually, the M-120L draws from Guild’s rich heritage with standout features like the period-correct tortoiseshell pickguard and the Chesterfield headstock emblem—both nods to Guild acoustics from the 1960s. These details, combined with a sleek natural gloss finish and mother-of-pearl rosette, give the guitar a refined yet familiar look. It also includes high-quality hardware like vintage-style open-gear tuners, a bone nut and saddle, and ivory-coloured bridge pins. Every element has been chosen to complement the guitar’s tone and appearance, and with the addition of a Guild Premium Acoustic Gig Bag, you can take this acoustic anywhere.
