Larry Robinson (Valley Ford CA) has been building guitars since 1972 and specializing in inlaying since 1984. He has has customers on six continents; his work has been featured in many museum shows and is in permanent collections of the CF Martin Co., Fender Instruments, Gibson Guitars, and private collectors.

John Mayer, Katy Perry, Dan Auerbach of the Black Keys, Jackson Browne, and David Grisman all have David's work in their collections. He worked on the Millionth Martin Guitar with world-class inlay artist Larry Robinson, and his work has been exhibited at the Museum of Making Music in Carlsbad, California.



Bob Hergert (Port Orford, OR) started doing scrimshaw in 1978, strongly influenced by the Bellingham school in Washington State. A chance meeting with Eric Galletta of Galletta Guitars opened the door for Bob to do scrimshaw work for the Allman Brothers Band, the Beach Boys, and many other guitarists. He continues to work with other luthiers and inlay artists, including Larry Robinson and Harvey Leach. He collaborated with Leach on Martin Guitar's 1.5 millionth guitar – “da Vinci Unplugged” – now on display in the Martin Museum, and, more recently, with Robinson on the Steve Klein da Vinci homage.
