I too have heard that bass string should be put on soon after being made. On the other hand, I had a set made one time for a Marshall and Wendall grand. Then the project got set aside and I finally got back to it probably ten years later. I decided to try the strings and they sounded just fine. I certainly have had other sets for much longer than 30 days which also sounded fine when finally installed. Perhaps Dave Sanderson will get on and shed some light on this subject. Or has anyone heard a good answer from Mapes? Ted Sambell would probably also know the answer. My suspiciojn would be that there would be a tendency for the core wire slip back inside of the sinding (winding) if left too long without tension. Remember, the string is made on the string widing machine under considerable tension. I forget the exact amount but sort of recall a figure in the range of 70% of the tension when pulled to pitch on the piano. Obiously, if the core wire then slipped back inside of the winding, when the string would then be pul led up to tension, it w ould tend to open the windings and that would not be desireable. I too shall wait for a more definitive answer. Ed Hilbert Vermpont Chapter
