It always becomes a debatable topic when you compare building a guitar or buying a guitar. Actually, my brother is willing to invest in building a guitar, and I am totally against it. I think as a beginner, you shouldn't risk money based on some online instructional stuff.
Yes, he found several sources like the following ones to build guitar and select guitar kit. He is probably willing to make an acoustic guitar.
Do you think he is making the right decision? Or it is just a waste of time and money. All in all, we are confused and little curious about his investment. Because he is going to spend all of his saving that he earned via his freelance earning. He is only 18 years old. But yes, he is good at playing acoustic guitars and have good knowledge of guitar gears as well.
I would be thankful if you share some more sources and suggestions to build guitar. (If he insist to build his own as compared of buying a new one)
