Cello synthetic A string care.

- The synthetic core A string is quite fragile because the winding materials are very thin. This is why it needs to be handled more carefully.

- Repeatedly removing and refitting the A string will significantly shorten it's life . We recommend that you don't do this if you want your A string to last.

- It's durability also depends on the condition of bridge and nut grooves. The grooves should match the string diameter, be smooth, and there shouldn't be any sharp edges.

- Graphite (pencil) lubrication of nut and bridge grooves is strongly recommended.
