Overview

A jumbo acoustic guitar with a powerful voice and exquisite appointments.

The Martin J-40 Standard Jumbo acoustic guitar is a beautifully crafted instrument that delivers a balanced and powerful tone with exceptional projection and sustain. This guitar, featuring a tight-waisted jumbo body shape and premium tonewoods, is a favorite among singer-songwriters, touring musicians, and session players alike. With its comfortable playability, vintage-inspired aesthetics, and modern enhancements, the J-40 is ready to inspire your musical journey.

Jumbo Body and Golden Era Bracing for a Powerful and Balanced Tone

The J-40's jumbo body shape, combined with the Golden Era forward-shifted scalloped X bracing pattern, produces a tone that is beautifully balanced with a powerful response and projection. This combination of design elements allows the guitar to deliver a rich and resonant sound with exceptional clarity and sustain. The solid spruce top and East Indian rosewood back and sides further enhance the guitar's tonal complexity, providing a warm and expressive voice that's perfect for a variety of musical styles.

 

Modified Low Oval Neck and Ebony Fingerboard for Effortless Playability

This Martin jumbo acoustic guitar features a comfortable Modified Low Oval neck with a High-Performance taper, making it easy to play for hours on end. The ebony fingerboard adds a touch of smoothness and responsiveness to the playing experience, allowing for effortless transitions between chords and fluid lead lines. The 1-3/4" nut width provides ample space for fingerstyle playing and complex chords, while the 20 frets offer a wide range of musical possibilities.

Hand-Crafted Quality and Vintage-Inspired Appointments

The J-40 is built with the same hand-crafted quality that Martin has been known for since 1833. The hand-fit dovetail neck joint ensures a strong and resonant connection between the neck and body, maximizing sustain and tonal transfer. This guitar is adorned with vintage-inspired appointments, including Golden Era binding, an angled nut, a traditional volute, and antique white binding. These details not only enhance the guitar's aesthetic appeal but also contribute to its classic tone and feel.

Modern Enhancements and Plek'd Setup for Optimal Performance

This Martin acoustic guitar features modern enhancements that elevate its playability and performance. The aged toner finish gives the guitar a vintage look, while the gold open-gear tuners offer precise and reliable tuning.
