From Collings: "OM stands for “Orchestra Model,” but 80 years after this body shape was first designed it has become the most popular 14-fret model with fingerstyle guitar soloists who choose to play on steel strings. Yet flatpickers also find it appealing. The compact shape makes the Collings OM equally easy to handle onstage or when sitting on the couch, and the relatively shallow body – barely over 4 inches deep – results in a balanced tone and immediate response."
This example is upgraded with an Old Growth Sitka spruce top. Includes OHSC.
