Well I want to build an acoustic guitar but need help. Like what wood should I use? How do I shape it and all that. Basically any help would be great,
Get a book on the subject, there are plenty of them on Amazon.com and such. Also if it's your first build, I would either get a kit, or do a solid-body electric. An acoustics tone is formed more by the luthier's skill than the wood it's made of.
Buy the book "Guitarmaking: tradition and technology" by cumpiano and nateson. It is -the- book of acoustic guitarmaking. Read the book a few times before even buying materials.
