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.

- We have been treating the nut groove area of the A string since May 2010 with graphite varnish. The treated area should match your nut unless your tailpiece is too short or long. The bridge area cannot be treated, and this is why lubricating the A string bridge groove with pencil graphite is important.
