S.B. MacDonald Custom Instruments vintage Gibson L-00 guitar headstock is a climate-controlled and fully insured guitar and stringed instrument building and repair center located in Huntington Long Island, New York. Clients are seen one at a time, by appointment only to ensure a personal touch and pay complete attention to your needs.

My goal is to take such good care of your instrument that you'll never go anywhere else. The workshop contains the best machinery, fixtures and tools, and matches the humidity levels at major manufacturing companies to provide the proper environment for stable repair, restoration and custom guitar building. The shop has 4 workstations, including a dedicated bench for neck resets and vacuum-clamping. Each zone is specifically allocated for certain tasks, to facilitate consistent results and quality control.

Broken Martin Neck (before and after)

There were fragments of mahogany missing from this shattered neck due to an accident where it was stepped on. After the neck was structurally repaired, graining pens were used to carefully paint in the grain to recreate the natural look of the wood before respraying and buffing the neck. The final result is nearly invisible, and virtually undetectable to the touch.

Martin J-21 Crushed Side (before and after)

The rosewood lower side on this Martin J-21 was splintered and shattered, with bits and pieces missing. The damage was repaired by gluing, filling, and carefully sanding the area level. The grain was painted in where missing to recreate the look and spirit of the wood. The area was then resprayed, feathered in and buffed to a gloss. More samples of structural repairs like this are in the articles above. (There is no photo retouching in any of my photographs).

Banjo and Ukulele Repair and Resotration

I am also a banjo and ukulele historian and have many parts dating back to the 1800s.

Guitar Refinishing and Touch-ups

Finishes and touch-ups are done in traditional lacquers as well as cutting edge ultra-violet cure lacquer. This means work can be performed on Taylorm Tacoma, and other manufacturers using UV lacquer and the results will blend in with the factory finish.

These articles contain many detailed photos and explanations of the work as it's being performed, as well as general care and maintenence advice.
