CJ MhThe Collings Jumbo, or CJ, is our version of the classic slope-shouldered dreadnought, a shape that has enjoyed renewed popularity in recent years. While the CJ is similar in width and depth to the traditional dreadnought, it has a distinctly different tone. Despite its large size this model works well with the optional shorter string scale, resulting in a somewhat percussive bottom end ideal for acoustic blues or other styles that benefit from a more controlled bass response. Of all the Collings body shapes, this is the one most often requested with a sunburst top finish, and the wide range of wood options, neck widths, and string scales allow the CJ to be many different guitars to a wide variety of players.
From the starting point of the wood's density and rigidity, each acoustic guitar top is hand selected, evaluated, and graduated to its own unique thickness; maximizing the tonal potential of each top.
Each Collings acoustic guitar, from our most affordable model to the highest end, are built with the finest tonewoods available. Each wood is acquired, acclimated, and hand selected by master luthiers here at our shop who pick each component with the whole tonality of the end instrument in mind.
A combination of exacting PLEK machine leveling and hand fret dressing ensures consistently excellent playability and a silky fret feel.
By meticulously hand-sanding between coats, our nitrocellulose lacquer finishes measure between .005” and .007” in final thickness, maximizing acoustic response while providing excellent protection and aesthetics.
Premium Waverly open-gear tuners offer exceptional tuning stability and smooth reliable operation with a vintage aesthetic.
The CJ features a fully bound top, back, neck and haircut-style peghead with black/white top purfling.
