What if an acoustic guitar swapped wood for stone? BeBeau Builds answers this by crafting 48-pound acoustic guitars from 18 pieces of slate. Weighing a hefty 48.7 pounds, this guitar defies norms by functioning as a traditional acoustic instrument despite its unconventional build.
Transforming flat stone into a resonant body through unique design
Creator BeBeau Builds begins by experimenting with body shapes, ultimately choosing an angular form. Using 3D-printed templates, he transfers these designs onto slate, but cutting the inch-thick material proves difficult. The process involves assembling around a repurposed acoustic guitar neck, highlighting the challenge of forming a closed volume from irregular stone slabs.
For another innovative twist in musical instrument design, explore how Brian Yu’s 3D-Printed Piano Revolution pushes boundaries with futuristic technology.

The initial attempt reveals alignment issues, as variances in slate thickness affect cut angles. A second attempt uses exterior dimensions to guide construction. Temporary hot glue frameworks allow for adjustment as construction adhesive sets, accommodating the natural behavior of stone. This meticulous method is part of the journey of making these distinctive musical instruments.

From slate to sound through innovative construction techniques
The project advances as BeBeau Builds replaces a broken stone panel and fills gaps between sections. Mineral oil coats the slate, providing a smoother finish before the instrument is strung. Despite its weight and planar aesthetics, the crafting of the stone guitar retains the outline of a traditional acoustic.

Surprisingly, the guitar’s sound resembles that of its wooden counterparts, though notes from the slate version fade quicker. The heavy body feels awkward, but pressing strings still produces a recognizable tone. The transformation in this ambitious project lies in weight and construction rather than voice.

Ultimately, BeBeau Builds demonstrates that a guitar built from stone can still resonate musically, answering the project’s central inquiry by merging familiar acoustics with robust materials through his unique crafting methods.
