This is a sweet little OM, I wasn't sure if I'd like the all mahogany, but I do - very much so. I also have a maple back/sides-spruce top 12-string jumbo, and a rosewood b&s-spruce top 6-string dreadnought. I was looking for a very different voiced guitar, something more focused -not so rangey as a jumbo or a dread.
This little doll is great for Sunday afternoon noodling, or as a darker woody voice in a Friday night 4-pc ensemble, or a Saturday country or blues jam session. The latter categories is where the Guild has excellent communication abilities. Pull out your best Woody Guthrie, Bob Dylan, the Civil Wars, the Decembrists, Sara Jarosz stylings and the M-120E will nail it. It has a tight punchy voice that belies its small as a minute size. And it is rather ergonomic in regards to the guitar-human interface that I wasn't prepared for, but love. Now the other place this little bugger shines is swampy Delta blues. I slacken the strings a bit and slide a small metal screw driver under the stings@the but and get my brass slide and conjure up my best Robert Johnson, Muddy Waters, Howlin' Wolf imitations. Again, I wasn't prepared for how adapt the Guild is in these circumstances.
It's not a lot of money, but it delivers tons of enjoyment. One could easily spend 2.5 Xs the money and get noticeably less tone & return on their investment.
Plugged in to an amp it delivers an acceptable tone for small venues; mic it with a Sure 57, or better yet some steam-punk goodness from Ear Trumpet Labs and it sounds full and sweet with very clear definition.
I am one of those guitarists that cannot leave well enough alone: so I sanded to neck slightly with steel wool then buffed it using carnuba wax & a buffing wheel to make the neck faster because it's a tad slow with the factory satin finish. I also replaced the black pick guard with a tortoise shell one, change the strings to Cleartone, & lastly changed out the OEM plastic bridge pins with Martin ebony pins. Visually the new pick guard lends an old time look to it, circa 1920s-30s. The new bridge pins tune the tone slightly warmer. I have to say this is a go-to kind of acoustic, and it even comes with a nice factory Guild case! Which is becoming rare at this price point.
