So being a guitar player many years ago I always replaced a broken string with a new one of my favourite brand at the time . Poked the end of the string through the tuner and left the excess hanging in the wind as it were.
I’m in the process of tidying my old faux-Gibson SG bass and thinking about strings.
I have a set for 34” scale bass but the SG is only 30” so do I …
1/ Use the strings and cut off any excess
2/ Buy specific strings possibly flats for a short scale bass
