It took the right strings to fine-tune my OM. I’d used D’Addario EJ16s on everything for twenty-some years, with the general proviso that strings don’t really matter. The EJ16s were fine – or so I thought.
Swapped out to the SCGC low tension set several years ago, and bang, the midrange on the instrument came out, string-to-string clarity improved (important for jazz chords), and the voice overall is better balanced. It handles dropped tunings better as well. And I’ve had to eat my words insofar as acknowledging that string choice really can make a significant difference.
Little things matter more than we let on sometimes.
ps I may have played that F – it’s a non-cutaway, right? That is a BIG guitar.
