BeBeau Builds Constructs 48.7-Pound Acoustic Guitar from 18 Slate Pieces
BeBeau Builds has crafted an acoustic guitar that features a body constructed from 18 pieces of slate, totaling 48.7 pounds. The endeavor started with the observation that struck slate produces a prolonged metallic sound, suggesting its resonance capabilities. By utilizing a repurposed acoustic guitar neck, the creator designed body shapes using 3D-printed templates. The first assembly attempt was unsuccessful due to inconsistencies in slate thickness, but the second try proved effective by employing exterior dimensions and hot glue for temporary support. After repairing a damaged panel and sealing gaps, the guitar emitted a tone akin to that of a wooden acoustic, albeit softer and with reduced sustain. This process is showcased in a September 2026 YouTube video titled 'I Made a Literal ROCK Guitar,' which addresses the difficulties related to weight and neck angle.
