I am delighted with the combination strings I have received for my Cello . Larsen Soloist A & D ..Spirocore Tungsten G & C . The strings arrived when you said they would - well packaged . What a difference to the sound of my French Cello ..singing sound at the top & the wonderful rich sound at the bottom ..particularly enjoy playing my C string now 👍 I read your comprehensive guide ..& as a consequence , now have a set of strings which show off my French Cello to the best 😃 I have recommended you on FB & Instagram ..the sound now produced is so, so much better ..& friends have noticed 👍 So ..I’m delighted 😃 Thanks 🙏🏽
