Upload a clip. Get reviewed.

One take, up to sixty seconds. Film from your front side with the whole neck in frame so both hands are visible - that gets you the full review. Hit record a second before you play: that bit of quiet is how I tell your guitar apart from anything else in the room.

Tonewood may keep this clip to improve its analysis. Your review works the same either way, and deleting the review deletes the clip and this permission with it.

The analysis takes a few minutes. Every timestamped claim in the report comes from signal analysis of your clip, never from a model guessing. Five reviews per day during beta. Your clip is stored only to generate and show your review.
