I hope that if you are reading this you give it a go,
Step 1: What you will need
6 new geared tuners £7
Wood for the head (pine)
Wood for the strengthener (Mahogany)
Wood for underneath the bridge (Pine)
12 Sting nut 99p
And you are ready
Step 2: Modify the Head
After doing this I marked on where I was going to cut the top of the head because it had a curvy bit.(Photo 1) After this I took a tenon saw to it and cut it.
For the new head I had 15mm pine, this was the same thickness as the original head. As the original head went from 65mm to 75mm over 130mm I cut the new head to be 75mm at the bottom and 85mm at the top.
