I strung natural gut once with my stringing machine, but 'bruises' natural gut too much, so I stopped stringing. I don't have an option to adjust my tensioner. Somebody on this forum already told me to wax and pre-stretch the string. Does anyone has more tips to keep it from bruising and will this bruising affect the charicteristics of the string? Maybe it is better if I don't waste my money on NG? thanks in advance.
