BUILT AROUND THE PHOTO
Start with what you can actually see.
Keep evidence in view
Review visible grain observations alongside material candidates, their evidence, and the limits of the photograph. A useful next angle should be easy to understand.
Context with clear limits
Read a visual assessment and, when reviewed sources are available, typical tonal context. These are not laboratory measurements or promises about an instrument.
OBSERVATION IS NOT CERTIFICATION
A photo can suggest.
It cannot certify.
An opaque finish can hide the wood. A surface image cannot establish species with certainty, solid or laminated construction, moisture, stiffness, authenticity, market grade, or the sound of a finished guitar. Treat results as a starting point for informed questions.
MADE FOR THE WHOLE GUITAR COMMUNITY
Electric. Acoustic. Classical. Jazz. Bass. Tonewood.
One approachable field guide for players, buyers, collectors, and luthiers. Save observations and lightweight guitar notes on your device, and keep the attention on the instrument and its materials.
Look closer.
Stay curious.
ToneGrain is being built for people who care about what a guitar is made of—and know that the best answer starts with good evidence.
