Guild has lifted the lid on two new USA-made concert-sized acoustics, the M-50 Standard and M-40 Standard, with smaller bodies and wider nut widths aimed at singer-songwriters and fingerstyle guitarists.

A concert-sized body is essentially smaller and less deep than that of a standard acoustic guitar, and so is ideal for smaller players, or perhaps those seeking a travel guitar.

Both the M-50 Standard and M-40 Standard are available in acoustic and electro-acoustic configurations, with the latter featuring an L.R. Baggs Element VLC Pickup System, designed to “faithfully reproduce the guitar’s acoustic sound when amplified or recorded”.

Though similar, each guitar sports a slightly different build; both feature a solid Sitka spruce top, while the M-50 Standard features an Indian rosewood back and sides, and the M-40 Standard features a back and sides built using African mahogany.

Both guitars have two finish options; the M-50 comes in either Natural or Antique Burst, while the M-40 comes in Natural and Pacific Sunset Burst.

Guild says the Indian rosewood of the M-50 Standard contributes to a “full and rich tone with excellent articulation”, while the M-40’s African mahogany means “warmth and an earthy richness”.

Further specs present on both models include a mahogany C-shaped neck, Indian rosewood bridge, compensated bone saddle and bone nut, tortoiseshell pickguard, white binding, Guild Peak headstock inlay and Guild Deluxe Vintage open-gear tuners.

Of the L.R. Baggs electronics featured on the M-50E and M-40E, Guild explains: “By detecting soundboard movement rather than picking pressure, the pickup captures the full and balanced tone of the guitar while eliminating the high-frequency ‘quack’ typical of undersaddle pickups.”
