Assembling the raw materials (e.g. tonewoods)
Making or sourcing the mold
Making the soundboard
Book matching the top
Marking out the soundhole and installing the rosette
Planing and thicknessing the soundboard
Bracing

Assembling The Raw Materials
The guitar building process begins with the assembling of raw materials, aka tonewoods. When it comes to building an acoustic guitar this means selecting the wood for the body (soundboard, back, and sides), the neck, fretboard, and bridge.
Each component of the guitar plays a different role in how the guitar sounds and plays, and as a result, may utilize different materials and different species of timber that have different characteristics.
