Call 570.321.8070 or e-mail us for assistance. If emailing, please mention 1. the type of instrument (violin, viola, cello, or bass), 2. the size of the instrument, and 3. the name of the string needed. We will mail a replacement string immediately. Strings are the only part of the rental outfit not covered by insurance, so payment may be made from the credit card on file. The teacher can put the string on the instrument for the student.
