Mayan Obsidian Epoxy Resin Guitar knobs
Introducing Mayan Obsidian, a one-of-one handcrafted set of resin guitar knobs blending deep carbon black with rich, metallic Mayan gold. Inspired by volcanic obsidian and ancient goldwork, this set adds a bold, luxurious, and historical character to any guitar.
Each knob is individually poured, sanded, polished, and fitted by hand in the Epoxica workshop. No two will ever be identical — the resin swirl patterns form naturally, giving your instrument a true artisan-crafted aesthetic.
Price range: $18.99 through $50.00
Hand-Poured Epoxy Resin Construction
Each knob is produced using premium casting resin and pigment blends to achieve depth, durability, and a polished boutique appearance.
Forged Grip Design
The textured grip profile provides improved tactile feedback when adjusting volume or tone controls during performance.
Stabilized Insert Casting System
Our knobs are produced using a stabilized insert casting method that holds the internal brass insert in position during curing to ensure:
• Accurate insert alignment
• Clean bottom surface finish
• Reduced internal porosity
• Consistent structural integrity across production batches
This method results in a stronger, more refined knob compared to traditional post-installed insert designs.
