Start off by getting everything you need together. I'm using Martin .010's. 80/20 Bronze strings
Start by removing the face plate
Pick a set of two strings to remove. I'm starting off with the G's
If your mandolin has a floating bridge, NEVER remove/apply more than two strings (one set) at a time.
When loose enough, unhook the string
Get your new strings
Hook on your new strings
Feed string through the eyelet
Bend string and start winding
Repeat process until finished
Replace the base plate once finished
Cut excess string
Old and excess strings? You can throw them away, or do something creative with them. I make dream catchers with mine.
