Redwood Burl – A legendary wood from the ancient giants of the California coast, Redwood Burl represents nature's most dramatic and prized grain formation. Born from stress and time in the majestic Sequoia sempervirens, these burls develop into massive growths with wild, unpredictable grain patterns that create some of the most sought-after wood in the world. Each set reveals an intricate tapestry of swirling eyes, deep mineral streaking, and explosive figure that ranges from rich burgundy reds to warm amber tones with dark mahogany accents. This is old-growth character at its finest, with dense, complex figure that only centuries of growth can produce. The depth and visual complexity creates an almost three-dimensional effect, as if you're looking into the heart of the forest itself.
Our Fall 2025 Caldera Open LTD in Redwood Burl features black rods and grille with striking maroon grille cloth, creating sophisticated contrast against the wood's warm, organic tones. Choose between a black aluminum chassis with Ruby BBB hardware, or upgrade to our new Custom Mg12 chassis in Ruby with matching BBB for reduced weight and a unified aesthetic.
Sonically, Redwood Burl's dense structure provides excellent damping and tonal control, enhancing the Caldera's legendary resolving power while adding natural warmth and textural richness. Each set is ethically sourced and represents a piece of living history—a functional heirloom connecting you to the ancient redwood groves of the Pacific coast.
