One of Guild's Original Designs

This Guild M-20 6-string acoustic guitar marks Guild's return to the US-made model that was the first to roll off the company's Westerly, Rhode Island, factory line in 1967. This stripped-down guitar boasts a top, back, and sides constructed of solid mahogany. The M-20's concert body style's compact dimensions ensure that it's very comfortable to play and sings with a midrange-focused tone that is marvelous for strumming or fingerstyle playing. The Guild M-20 6-string acoustic guitar offers vintage-style looks, feel, and tone.

Guild M-20 6-string Acoustic Guitar at a Glance:
  • One of Guild's first acoustic guitars
  • Straightforward mahogany construction
  • Comfortable concert body
One of Guild's first acoustic guitars

The Guild M-20 6-string acoustic guitar is a modern version of the very first model to ever be produced by Guild's Westerly, Rhode Island, factory in 1967. And it appropriately coincides with the reintroduction of US-manufactured instruments for Guild Guitars. Even many of the materials and machines used in the crafting of the M-20 acoustic guitars came from the original Westerly factory and were responsible for many of the company's earlier models. Sweetwater is proud to offer you this piece of Guild's history.

Straightforward mahogany construction

The M-20's neck, top, back, and sides are constructed entirely from solid mahogany. This tonewood was chosen for its centered tone that exudes warmth without ever becoming muddy, and clarity that never sounds shrill. The rosewood fretboard and bridge further help to enhance the guitar's harmonic overtones, and the M-20's appearance is as warm and inviting as its tone. Minimal aesthetic appointments give the instrument a vintage look that works as beautifully onstage as it does around a campfire.

Comfortable concert body

Smaller-bodied acoustic guitars such as this Guild M-20 have been a popular option among players since the dawn of the instrument. Its concert-style body in particular is a favorite for this midrange-focused tone that helps each note come through loud and clear. This makes the M-20 a wonderful option for fingerstyle players and flatpickers alike. And the guitar's smaller dimensions are very comfortable for the performing guitarist that needs to have the M-20 slung over a shoulder all night long.

Guild M-20 6-string Acoustic Guitar Features:
  • 6-string acoustic guitar built to vintage Guild specs
  • All-mahogany construction offers a warm, balanced tone
  • Thin satin finish lets the wood vibrate freely
  • Minimal aesthetic appointments offer a vintage appearance
  • Concert body style is comfortable and even sounding
The M-20 is a great example of Guild's rich history.

The Small Mahogany Throwback I Was Looking For

I was looking for a small-bodied solid mahogany acoustic guitar that could translate the feel and warmth of a vintage tenor ukulele to the 6-string format. This Guild M-20 fit the bill and beat the competition for several reasons. Martin's 00-15M is a nice instrument, but is larger in scale than I was looking for, as the ability to play at home in an easychair is important to me. Smaller, more comparable vintage Martin 0-15's are too expensive and precious, though the scale of the M-20 is closer to the 0-15, or perhaps Martin's "retro" acoustic electric, or even their spruce-top "whisky sunset" model, which I wasn't crazy about the phony "aged" looks of, given their high prices. I found the Taylor GS mini to be uncomfortable. Well, I played 'em all, and found that I liked the wider 3/4" nut spacing of the M-20 best for the fingerpicking I'm accustomed to. I also liked the modesty of the dark satin finish. I found the price to be more fair, and found a friendly local dealer. ;) But most importantly, it had THE SOUND! The Guild M-20 is warmer, mellower, woodier and well-suited for fingerpicking. It is not as bright, metallic, or piano-like in tone as any of the alternatives. In my case, its distinct mahogany tone was just what I was looking for! The videos online are a fair and accurate representation, but I suggest trying one for yourself.

Best guitar I have ever owned

I purchased the Guild M-20 from Sweetwater about a month ago. I was a little hesitant about ordering a guitar online-- especially one at this price range-- but the experience has been flawless. Aaron, my sales engineer, was extremely helpful and professional. Unlike other sites, Sweetwater provided a high-res photo of every angle of the guitar. Several guitars actually, that I could then choose from. And what a beauty it is! This was the first guitar I have bought that I would consider "high end". I know its all relative, but I add this just to get a sense where I'm coming from. For instance, did you know some guitars don't come with the end pin in place? I didn't, and found it in the case compartment. BTW- this guitar does not have a strap pin where the neck meets the body-- if you need a strap it will need to be the kind that fastens to the headstock. The finish and understated look of the guitar is just awesome. No fancy bindings and bling, just tastefully austere, which fits my style. I was thinking about the M-120 for a while, but I just couldn't get over the glossy finish. That and the desire to buy an authentic American guitar. The M-20 is really small, lightweight and comfortable to play. I was looking for the ultimate couch guitar and I think I have found it. I know tone is subjective, but it brings a smile to my face every time I strum it. Perfect for the music I tend to noodle around with: Bob Dylan, Townes Van Zandt, Elliott Smith, etc. String action straight out of the box was good for me-- low action, very easy to play, no noticeable buzzing. My wife, who is just beginning to play guitar, finds it much easier to play than the old Ovation we have sitting around. Simply a stellar guitar, that makes playing music more enjoyable. If you are waffling between the M-120 and M-20, I would go for M-20 if you can swing (the not insignificant) extra cost. If you are looking at a Martin 00-15 or similar, I think this guitar more than holds its own. I highly recommend it.

Excellent Tone!!

I'm a mahogany fan and this was my first all 'hog guitar. All I can say is that I'm blown away by the sound that comes out of this thing. It is clear and punchy from lows to highs. The body is so comfortable to hold and the finish is great! Definitely recommend to those looking for a break from their dreadnaught.

Sweet Parlor Guitar

Just a sweet little player. It sounds great and I just don't think you'll find a better deal on an American made acoustic guitar. I've always had a soft spot for Guild and now, under the Cordoba umbrella, the brand is back to making really nice, straightforward players. Of course, Jim Watson was easy to work with as always. I've never had a bad experience with Sweetwater.

Guild M-20 - Natural

Absolutely the best deal in a USA made guitar. Sweet , full, rich mahogany sound. Inch and 3/4 nut with 2 1/4inch saddle spacing makes for great finger style. Shallow body makes for great sofa noodling. Bone nut and saddle! Surprisingly loud living room filling gusto. Frets and intonation spot on. Neck finish not the greatest (we are talking inexpensive here) but still slick and fast. As always, Sweetwater set up best in the industry (I should know, # 4 from them). I will add bone bridge pins, but I do that with all my acoustics even those with ebonies. Great serious starter guitar (having an easy playing, great sounding instrument makes practicing a joy) or a must have mahogany for your budget minded collection.
Music background: Thirty years of mostly fingerstyle.
