D'Addario Composite J4505C - 5th string (A), normal tension .035

Exactly what I needed delivered promptly with attention to customer service. I will return as a need arises.

I find that this string can be combined not only with the 6th from the same set (4506C) but other 6th strings of both normal and high tension - it's bright but not excessively so and has great volume and projection. The D'Addario composites seem to be more stable than many other types, so after a few days of playing in, little or no tuning is needed day-to-day.
