Fiberreeds last me about 10 months. It’s gonna differ for everyone depending on how much you play on it of course. I could see one lasting around 6-7 months of long daily use and up to 12 months or more for not so much use.
as for the lig I use it’s a Winslow and of course it’s got a patent.
I contacted John Winslow to see if he wanted to sell them on my site but he said no. Too many people have screwed him over the years.
I would see his lig on a site selling for $200-$300 when he sells them for around $80-$90.
There is a copy of his ligature called saxxas…it’s not as good but it’s a copy.
