Collings OM1 Made in USA Serial Number 11432 ‘OM’ stands for “Orchestra Model,” but 80 years after this body shape was firstdesigned it has become the most popular 14-fret model with fingerstyle guitar soloists whochoose to play on steel strings. Yet flatpickers also find it appealing, and when the graceful cutaway is added these OMs are often used by lead players who routinely explore all 20 frets much as they would on an electric guitar. 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 balanced tone and an immediate response.
