The Martin Style 3 is one step down from the 5K, but was also intended for use by professional musicians. It is still a very highly sought after instrument. Top quality vintage 3Ks can sell for many thousands of dollars.

The most distinctive features of the Style 3 is the } shape on the body and the stripe down the centre of the neck. The 3K model is exactly the same as but made from solid koa rather than mahogany. Today, the koa model tends to fetch a much higher price than the mahogany. Partly because koa is now much rarer and partly because they look much better (and, of course, there is the Hawaiian connection). There is some difference in tone, but I wouldn't say one is superior to the other - certainly not enough to justify the price difference.

Like the 5K, the 3K's popularity has lead to Martin resurrecting it. They currently offer a Koa Style 3 (at $1,899) and also a Cherry model (at $1,499).
