Applying lacquer to, or shellacking, a tweed-lined speaker cabinet helps preserve the aesthetic integrity of the instrument. When dry, lacquer creates a glossy clear coat that can protect the amplifier's tweed body from scratches, tears, dirt, liquids, stains and other visible flaws. Before beginning the shellacking process, remove all hardware components or mask them so the lacquer does not dry on surfaces where it is unwanted.

Things you need
- Denatured alcohol
- Mixing bowl
- Nylon bristle brush
- Masking tape
- Tape measure
- Plastic sheeting
- Steel wool
Lay plastic sheeting on the floor to prepare the shellacking area.
Unscrew the handles from the top and sides of the speaker cabinet.
Measure the grille of the speaker cabinet. Cut a piece of cardboard that will fit into the face of the cabinet to shield the speakers during the shellacking process.
Apply masking tape to any cabinet surface that is not lined with tweed.
Mix equal parts denatured alcohol and lacquer in a mixing bowl.
Apply the first coat of lacquer evenly using a nylon brush.
Check the surface of the tweed for any raised tweed fibres once the first coat has dried. Remove any raised fibres with steel wool.
Repeat steps 6 and 7 until the tweed surface is smooth.
