The size 5 was the smallest body size made by Martin! It makes a perfect travel guitar for someone that wants a high quality instrument in a compact package. It's had a neck reset and the saddle slot recut for perfect playability and intonation. The original frets have hardly any wear and it comes with the original soft shell case. It has the typical repaired crack by the pickguard under the B string. It can be tuned to standard or up a minor third like a terz guitar (standard tuning with a capo on the 3rd fret) for players in the studio that want a different tonal flavor. This is likely the best sounding and playing 5-18 you'll find thanks to the repair work that was done. It would make a fine travel guitar or addition to your studio arsenal.
