I have heard it said more than once that fresh strings are a prerequisite for a recording session. Being one who changes their strings fairly often, this is never a problem. But the other day, I picked up a used guitar that was quite inexpensive due to some issues, and decided to record it, before doing anything to it other than truss rod adjustment. The strings were obviously old and tired, yet I really liked the sound of the guitar as is. It had a very dry, snappy, and bluesy sound, with a respectable bottom end. After recording, I changed the strings. I did not like the sound as much, but frankly how it sounds on tape is the more important aspect. O.K., I know my computer has no tape, but it sounds much better than saying how it sounds on "ferromagnetic hard disk platter material" Well, truth be told, I liked the recording of the old strings better, and by no small margin. I am at a loss to understand this.
