| Glaesel/Scherl & Roth is now part of the Conn-Selmer music conglomerate. The model number you list does not appear on their current list. At one time, S&R, based in Cleveland, was known for imoorting some of the better student/intermediate grade strings from Germany, and the "Roth" part of the time was one of the brothers of E.H. Roth.
More current S&R instruments come from China, Romania, and, in some cases, from Germany. The overal quality is not as good as earlier products, but their better models may be somewhat decent.
You might want to try and contact Glaesel/Scherl&Roth and see if can proved some info as to your specific instrument. Be warned, however, that they are not very receptive to inquiries and may well ignore you or blow you off with some useless response. |
