What We Think

Returning to your roots often yields the sweetest fruit--it just doesn't get sweeter than this new model from Collings!  This guitar hasn't just been inspired by vintage design; Bill Collings and his team have committed to making a genuine, thoroughly researched, classic OM.  The spec sheet alone had us excited (not to mention the handmade case that comes standard)!  You just don't see this level of care and consideration in many guitars and the result here is an instrument that truly sounds old, wizened, and complex.  The Adirondack top breathes all the more freely thanks to the hide glue, unusually-thin nitro lacquer, and scalloped bracing specific to the Traditional series.  The dynamic range is both sophisticated and balanced.  Very full, almost slope-shoulder-like bass, warm but never woolly mids, and clear, sparkling highs free from any trace of the strident voice a new Adirondack top starts with.  This OM1 AT sounds like its been singing for years--the music has only just begun!

Manufacturer's Description from Collings

The Traditional or "T" Series guitars reflect Bill Collings' return to his guitar making roots and offer a new tonal variation on the distinctive Collings sound. Each T Series guitar is built using animal protein glue and a very thin all nitrocellulose lacquer finish on the body, making them exceptionally dynamic and responsive. Bracing and tone woods are adjusted for weight and thickness to create a voicing characterized by warm, rounded highs and a present low midrange, while retaining a quick attack and strong projection. Each Traditional series guitar will come with a handmade lightweight Collings case designed and built in the Collings shop. The pairing of these new Traditional guitars and cases makes for a combination of old world quality and aesthetic that is unprecedented among instruments available today.

About Manufacturer

Sound Pure is a proud dealer of Collings Acoustics, Electrics, and Mandolins, with a large inventory and new guitars arriving regularly.  Each instrument in stock is professionally photographed, and we have video reviews with studio-quality sound and HD video quality.

Bill Collings has been inspiring generations of guitarists with his fine guitars and mandolins since the 1970s. After dropping out of medical school to pursue his interest in guitar building, he moved to Austin, Texas where he and his company, Collings Guitars, operate to this day.  From his humble beginnings as a one-man operation in a two-bedroom apartment to his current 22,000 square-foot facility and approximately 70 employees, Collings has built a reputation for producing high quality instruments with care and precision. 

Perhaps best known for flat-top acoustic guitars, Collings excels in a variety of classic-inspired designs and modern build concepts. Their D series guitars represent their take on the iconic 14-fret square-shouldered dreadnought and include the highly-favored D1 and D2H models with mahogany and rosewood back and sides respectively. These guitars are extremely well-balanced and have a strong reputation for reliability and consistently becoming stronger as the woods open up over time. The CW models in this series feature Adirondack tops, larger sound holes, and other specs especially coveted by bluegrass flat pickers for their volume and responsiveness. The Collings OM series guitars tend to be lively, balanced, and lyrical. These guitars are hugely popular amongst fingerstyle players for their dynamic sensitivity, size, and playability. One of the most versatile acoustic guitar designs, Collings OMs can also handle heavy strumming and flat picking easily when the player needs to dig in. The CJ is a fantastic slope-shouldered dreadnought, and the SJ is their incredible small jumbo design. Collings also makes astounding parlor-style 0, 00, 000, and Baby guitars, which are perfect for performance or travel and offered with the same variety of options as the larger lines for true customization of tone and appearance. Rounding out Collings’ acoustic lines is the C10, which is modeled after a parlor guitar but with a design concept that makes it a favorite of electric players.

Collings is ahead of the pack in the acoustic guitar game, but it certainly does not end there. Their electric guitars are highly regarded amongst players across the entire spectrum of musical traditions. Designed and built with the same knowledge and attention to detail as the flat-tops, Collings electrics are quickly gaining recognition as contending with the best of the best of electric guitars. Hard rockers and country pickers and everyone in between can find a Collings electric to fit their style, from the Les Paul-inspired shapes of the 290, 360, and CL series to the semi-hollow I-35s and SoCo Deluxe models. Collings also offers A and T-style mandolins, as well as concert and tenor ukuleles. 


Every Collings instrument has been built with the same standard of craftsmanship and quality that any discerning musician deserves to experience in the tools they select for their musical journey. At Sound Pure, we believe that the tools you equip yourself with can either enhance or hinder you on your journey, so we make it our job to research and choose what we find to be the very best instruments for our clients. We are confident that any Collings guitar that leaves the shop will meet their standards, as well as ours. If you find that we do not currently have the exact specs you need we are happy to make custom orders for our customers to build their own dream guitar.
