ToneProof creates secure registry records and uses patent-pending wood-grain signatures to help identify and verify qualifying instruments over time.
Trusted by musicians, collectors, builders, and shops who value provenance, documentation, and long-term confidence.
ToneProof registry records are designed to support provenance, resale, and insurance documentation.
Check whether an instrument already has a ToneProof registry record. Enter a Seal Code or, if signed in, compare a wood-grain image against the registry.
Check Registry
Create a secure ToneProof registry record with instrument identity details, archive images, condition notes, and optional wood-grain signature capture when visible.
Start Registry Enrollment
Book a guided ToneProof Verification Service session to strengthen registry confidence, document condition, review identity details, and support resale or insurance documentation.
Learn About VerificationWhen visible, wood-grain signatures can be captured during Registry Enrollment or a Verification Service session to support future registry checks.
ToneProof was designed to support the long-term identity lifecycle of wooden musical instruments — from manufacturer or builder origin records, to musician and collector verification, resale, documentation, and future registry checks.
At the center of this lifecycle is ToneProof’s patent-pending wood-grain signature process, which helps connect an instrument’s natural grain patterns to a persistent registry record.
Every wooden instrument has a naturally unique grain pattern. ToneProof captures that pattern and anchors it to a registry record so the instrument can be identified and verified over time.
A clear photo of the instrument’s wood surface is captured during Registry Enrollment or a Verification Service session.
ToneProof analyzes the wood grain pattern and creates a unique signature that represents the instrument’s identity.
The grain signature is stored in the ToneProof registry along with the instrument’s enrollment details.
Years later the same instrument can be verified by comparing new photos against the registry record.
