Our process restores any instrument safely, using premium materials. Now offering annual subscriptions for ongoing care—keep your guitar in top shape year-round.

Whether restoring function or upgrading with custom wiring, we ensure clean, noise-free installations that preserve and enhance your tone. Expect clarity, reliability, and peak performance from your electronics.
STRUCTURAL REPAIRS
Structural integrity is key to an instrument’s tone and playability. We repair cracks, breaks, and internal components with precision, preserving character while enhancing durability. From seamless restorations to neck resets, our expert craftsmanship ensures your instrument remains strong, resonant, and perfectly playable for years to come.
