As I understand it, there was a banjo player back in the late 20s who requested that Martin make a guitar with a slightly longer scale, which may or may not have been 25.5 specifically, but that's how the OM Martins came about. It's not so much an advantage' date=' it's just a choice. I 'get it', I just can't put it into words. A longer scale guitar is like a group of (equally talented) singers but you can pick each one out even when singing together. Their voices blend smoothly and it all comes out as "one voice". Not getting all poetic, but one person described a shorter scale guitar as having a voice like a group of family members singing together. Made sense to me and I believed it as soon as I went from a 30" scale bass to a 34" scale. The notes seem more clear and defined and less like rubber bands.Ī longer scale guitar will have greater string tension but I can't quote the physics involved and I'm not prepared to defend it, I only recall reading (way before the internet) that two strings of different lengths tuned to the same pitch, the longer one is under greater tension. I never paid much attention to the scale length on a steel string acoustic but I will state a preference for a longer scale on a classical.

Again, it's all in the player's preference. The scale length will have a definite impact on the tone, all other things being equal.

It's not so much an advantage, it's just a choice.
