Guitar Doctor has been Orange County’s trusted destination for expert guitar repair and restoration for over 40 years. Master luthier Doc Pittillo brings decades of hands-on experience to every instrument that crosses his bench, from routine setups on student guitars to meticulous restoration work on vintage six-figure Gibson Les Pauls.

As an accomplished guitar maker himself, Doc understands the nuances of construction, tension, and finishes that many guitar techs overlook. This builder’s perspective informs his repair philosophy: use accurate restoration techniques that preserve an instrument’s original character and value, never doing more than necessary. His shop services the full spectrum of stringed instruments, including acoustic and electric guitars, bass guitars, mandolins, dobros, banjos, ukuleles, and lap steels.

The mellow, unpretentious atmosphere reflects Doc’s approach to his craft. Walls lined with Gibsons, Fenders, and custom boutique builds tell the story of his expertise, while glass cases display his handcrafted Pittillo guitars. Professional artists worldwide trust Guitar Doctor to keep their instruments in peak performance condition, a testament to the exceptional craftsmanship and attention to detail that defines this Costa Mesa institution.
