Travel with us now Back to the – no, not the Future, but – the 1970s! Back when things were all natural and stuff! Back to nature. Long hair. Deer-hide jackets with fringe. Back when the taste for things au naturale began to show up in guitars. Back when clearcoat finishes began to reveal alternating laminates of light and dark wood, often maple and mahogany or walnut. Back to a time when Martin built this 1979 Martin EM-18. Say what? Martin??
