สาย A ทำจาก Metal พันด้วย Stainless Stell Alloy
This string was originally developed as an alternative to the current A string for the Brilliant cello set. We had been concerned that the synthetic A string might be too fragile. However we solved the issue of the synthetic string durability and the metal core version started to take on a life of its own. It was tested by many players worldwide and the results were unexpectedly good. We therefore decided to add it to our range as a separate string.
