My L&H 85 E semi grand was just regulated I had not been able to do a full string change prior to the regulation. Sence the regulation 5 strings have broken 3 in Octave 4 and 2 in 3. The strings are 2 years old an I know they should have been changed it didn’t work out that way. My question is should I change all the strings and will it adversely affect this recent regulation?
