Alluvium Guitars is the vision of Todd Flak, an innovator and artist who approaches electric guitar building as both engineering and creative expression. Each Alluvium instrument is custom built to order in the USA, with no off-the-shelf templates or mass-production shortcuts. Central to the design is a louvered magnesium face paired with traditional tonewood back and sides—a deliberate material choice that reflects Todd’s focus on responsiveness, balance, and articulation. Magnesium shares many desirable qualities with aluminum, including rigidity and corrosion resistance, while being even lighter, allowing the guitar to remain highly reactive to the player without unnecessary mass

Todd’s use of magnesium is not a novelty, but a functional solution that supports precise louvered designs to manage airflow and vibration in ways conventional materials cannot. The result is an instrument that translates string energy quickly and evenly, producing clarity, dynamic sensitivity, and a distinctive tonal character that complements the organic resonance of tonewoods. This hybrid construction embodies Alluvium’s made-to-order philosophy: every guitar is built with careful attention to feel, tonal response, and performance, resulting in electric guitars that reflect both advanced materials engineering and the personal artistry of the builder.
