Gonzalo Madrigal started out at Fender in 1996 by binding and sanding guitar bodies on the production line. A superior craftsman, he gradually made his way to the Fender Custom Shop in 2004, where he worked on Benedetto guitar bodies, binding and neck fitting. He too worked on various high-profile "tribute" projects, including the Fender Custom Shop Eric Clapton "Blackie" Stratocaster, Stevie Ray Vaughan "Number One" and "Lenny" Stratocasters and Andy Summers Tribute Telecaster, and the EVH "Frankenstein" replica guitar.

Madrigal’s exemplary work also brought him to the attention of Stern and projects at the Gretsch Custom Shop, where he contributed to the Brian Setzer and Eddie Cochran 6120 models, the Billy Zoom Silver Jet, the G6128T-GH George Harrison "Tribute" Duo Jet and the G6131MY-CS Custom Shop Malcolm Young “Salute” Jet™.

After 12 years under Stern's tutelage, Madrigal was promoted in early 2018 to a Master Builder.

In his spare time, Madrigal enjoys playing soccer and basketball, and going to the movies with his family.

Chad Henrichsen joined the Gretsch Custom Shop in 2008, after spending four years with Fender as a guitar tech and, later, group lead of quality control/inspection.

Henrichsen brings that developed eye for subtle nuances and perfection to the Gretsch Custom Shop, where he specializes in crafting custom necks.

A tinkerer at heart, Henrichsen enjoys woodworking, modifying amps, fixing cars and building computers. Proficient on the guitar, bass, piano and drums, he says he takes the most pride in being challenged by requests from artists like Zac Brown (Custom Falcon and Custom Penguin), or Cheap Trick’s Tom Petersson (Custom 12-string bass) or Mike Campbell of Tom Petty and the Heartbreakers (Billy-Bo).

“I enjoy taking things apart just to see how they work and thinking of the different ways it could be made. So naturally, I enjoy a build request that is outside the norm which makes me figure out how to make it work.”
