What we build are not just guitars. Each one is a portal. Through its wood, its shape, its hidden lines, it carries codes woven into frequencies and resonance. When you touch its strings, you’re not just creating music. You’re crossing into a conversation that flows between worlds.
We don’t invent these instruments. We discover them. Every curve, every imperfection, every vibration exists because the language demands it. Playing a Tetro guitar isn’t performing. It’s opening a doorway.
There’s more beyond what you hear. Tetro exists because reality stretches far beyond its edges. And for those ready to listen, the guitar becomes a portal into something waiting to be found. Once you feel it, you can’t turn back.
