These snare wires was a perfect fit for my 10" Yamaha Snare (made in Indonesia) both sonically and as for their design. They worked well right out of the box without any adjustments, nor fine-tuning. I didn't use those laces that are being delivered with the snare wires, but used some good solid mylar Puresound's snare straps.
Fat Cat FCS10 worked perfectly! It might not work for you, but it did for me!
