Warchal Amber Cello A String synthetic core wound with hydronalium-stainless steel provides a slightly warmer tone than the alternate metal Amber A string
This string sounds really neat especially since I now have machine head tuners on the Cello & always keep the bridge & nut lubricated, plus I got a CodaBow Joule w/ Clarity Rosin, Coruss Synthetic Bow Hair, & a CelloPhant. I never had issues w/ this Synthetic Core A string breaking because a really neat trick I learned from a couple of other musicians (and my friend Michael Soares) is to let your A String stretch.
Reviewing a string is difficult to make meaningful. My cello has a very bright A string, almost stringent. I’ve tried many different A strings and have not found one that adds a sweetness and keeps the projection. The Amber Synthetic is almost there, but still looking.
I love these strings, and will buy another set soon. My cello was built in Germany and finished in Minnesota by Andrew Fein. It was delivered with Larsen strings, and these were too bright for me. The synthetic core Amber strings are perfect. I have a friend nearby and have recommended them to her. In order to be kind to the A in this set, I start the day before and tune the A up to an E lower. Then after a few hours, up to F. Then the next day I tune it up to a G, and finally after another few hours up to the A. This works very well, and I am still able to practice every day if I need to. The Amber Strings have a warm rich sound and are much louder than I expected, loud enough to be comparable to any other strings.
Didn't work out on my chinese cello because it is to bright, so the sound was too metalic for my ears. Someone told me they had a warm sound, but not for me. After, I had to buy a larsen, that was more expensive but gave me the sound I wanted.
