ToneProof captures the unique wood grain signature of an instrument and anchors it to a registry record — helping musicians, collectors, builders, and shops document provenance and verify identity over time.
Check whether an instrument already has a ToneProof registry record. Enter a Seal Code or compare a wood grain image against the registry.
Verify
Builders, luthiers, and partner shops create origin records when an instrument enters the registry, anchoring its identity from the start.
Access Partner Registry
Create a structured record of an instrument’s current condition through a guided session. Ideal for collectors, sellers, and insurance documentation.
Schedule DocumentationWhen visible, wood grain signatures can be captured and linked to registry records to support future verification. This step may be completed before a documentation session.
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 enrollment or verification.
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.
