The WARCHAL AMBER Cello A string is available in two options: metal and synthetic.
Because any cello synthetic core A string is quite fragile both in handling and durability we also offer a metal version of the Amber A string. It is the first time that WARCHAL newest invention, the helix solution, has been applied on a cello string. This improvement was originally invented by Bohdan Warchal in 2013 to solve the sound difference of metal E strings and whistling problems on violins. After its tremendous success Warchal applied their invention on metal viola strings too. Now cello players can benefit from a metal A string with increased elasticity which offers the most wonderful sound.
