RosewoodIndian / BrazilianSelect

Rosewood is the classic pairing for a spruce top. It is denser and harder than mahogany, which pushes the resonant character toward a deep, reverberant bass with rich overtones and long sustain. Strummed, it sounds big; fingerpicked, it sounds lush.

Indian rosewood is the practical choice: plentiful, stable and consistent. Brazilian rosewood is the traditional and now heavily restricted material, with a wider tonal spread and a much higher price. East Indian rosewood is what most modern guitars actually use, and the trade restriction on it is a real thing to check before shipping an instrument across a border.

Where this fits: SelectChoose and season the wood. Species, grain, stiffness and moisture content are settled here, and nothing later can undo a bad choice made at this stage.

At this stage

Rosewood is oily and springy. It resists bending until it is hot enough, and then it moves quickly, so the bend needs to be watched closely rather than forced.

Works with

  • Spruce top
  • Hide glue
  • Ebony fretboard
  • Nitrocellulose lacquer
Safety
  • Rosewood dust is a strong respiratory sensitizer and causes contact dermatitis in some people. Extraction, a respirator and gloves are all warranted.
  • Rosewood species are subject to CITES trade controls. Check the paperwork requirements before you buy, sell or ship an instrument made from it.

Working notes

  • Wipe the gluing surfaces with acetone or naphtha to remove surface oil before gluing.
  • Rosewood is heavy. A rosewood dreadnought will be noticeably heavier than the same guitar in mahogany.
  • Scrape rather than sand the sides — the oil clogs abrasive paper quickly.
  • Keep the CITES documentation with the instrument. It is what proves provenance later.
