Martin D-222 Anniversary Edition

£3,599/$4,999

First up is the D-222 Anniversary Edition, which is limited to 100 instruments worldwide.

This 12-fret dread features a Sitka spruce top with Vintage Tone System torrefaction, mahogany back and sides, grained ivoroid binding, slotted headstock and ebony fingerboard and bridge.

Commemorating what would have been Lennon's 75th birthday, this special-edition D-28 is limited to 75 instruments.

The guitar's solid Adirondack spruce top with Vintage Tone System is paired with Madagascar rosewood back and sides, while the back is inlaid with an HD-28-style zig-zag peace sign.

Personal touches appear in the Madagascar rosewood headplate with self-portrait illustration, plus the custom pickguard.

There are only 50 of these Orchestra-sized beauties available, which feature an ebony fingerboard, bridge and headplate, plus a solid Adirondack spruce top and figured koa back and sides.

The back of the guitar features a compass design inlaid with flamed jarrah, Claro walnut, waterfall bubinga and Paua pearl, while the ebony headplate bears a True North design inlaid with mother of pearl.

The most expensive of this year's models, the 000-42 Authentic 1939 is crafted with hide glue construction, dovetail neck joint, solid Adirondack spruce top with Vintage Tone System, solid Madagascar rosewood back and sides, and black ebony fingerboard and bridge.

Like the 000-42 Authentic, the 00-18 Authentic 1931 is a faithful reproduction of its namesake year's instruments, with hide glue construction, dovetail neck joint, Adirondack spruce top with Vintage Tone System, mahogany back and sides, and black ebony fingerboard and bridge.
