Aim straight at the front of the instrument. Fill the frame (≈80–90%),
avoid glare, keep it sharp. Turn off HDR in camera settings.
Upload 1–3 photos of the instrument's front. We’ll scan its
unique wood grain signature and check it against our secure registry.
✅ Good: Centered, straight, full top, no glare
❌ Bad: Cut off edges, glare, or angled
Verify an instrument
Upload 1–2 photos of the front. We’ll check against the ToneProof
registry and return a likelihood band.

If this instrument has a ToneProof hang-tag or seal, enter the
code printed on the tag. This tells ToneProof to look first in
that builder’s registered instruments. If there’s no seal,
just leave this blank.
If you know the make/model, adding it reduces compute and
false positives.
Having trouble with photo quality?
Fill most of the frame with the instrument’s top (≈80–90%).
Keep it sharp and in focus (no motion blur).
Use good, even light (no heavy glare or deep shadows).
Avoid fingers, capos, or labels blocking the wood grain.
Turn off HDR in your camera settings.
