This Collings Guitars - OM1 A T Series, here with an upgraded Sinker Mahogany back and sides, is a bold and focused guitar that delivers the warm tone and rounded high-end that we love about the traditional series. Occasionally an OM shows up here in the shop that can hang, and in some ways compete with a dreadnought when it comes to overall volume of sound, and this Orchestra Model certainly delivers on that front. The Adi top combined with the Sinker Mahogany back and sides delivers a low-end that reverberates against your chest while playing the guitar, along with driving the top that only gets better as the guitar warms up.

The Traditional Series is marked by a return to just that, traditional building techniques and materials combined with the Collings exquisite attention to detail. This series is highlighted by traditional style bracing and tone woods which are adjusted, weighed and voiced to produce particularly warm, rounded highs while maintaining a full, rich low end. The extra thin Nitrocellulose lacquer finish, makes for a lively, expressive top that has the feel of a vintage guitar. This also OM1 features the T-Bar style adjustable truss rod that comes standard on Traditional series builds.

This Collings OM1 Traditional comes with a Collings TKL hardshell case, and includes a free setup to your specs from our luthiers.
