I went to my local music shop and asked for my classical guitar to be restrung, and he made the 3 low strings steel and the high 3 nylon even though it's a nylon guitar.
Now the neck of my guitar is bent from the tension and I'm worried it will break.
What should I do now? I haven't tried any fix as I can't find one. I will be asking the shop about it in 1 week.
