Luthier

"From a young age I've always found myself wanting to know how mechanical things worked from pulling my vintage cassette and record players apart to finding vintage electric guitars and amps at flee markets and breaking them down and building them back up again. I'd Frankenstein several supposed junk guitars into one with  the best parts from each. 

As I got older my obsession continued from swapping pickups in brand name guitars and refinishing or stripping back paint jobs to reveal the natural wood to dressing fret sprout. 

When I became a pro touring and studio guitarist I found one of the best guitar techs in L.A. but always hated waiting several weeks to a month to get my guitar jobs completed. At this time, I figured I had to fill in the gaps of the knowledge I didn't possess and learn how to do a pro setup myself. This led me on a journey to learn electrical wiring, fretwork, finishing and everything needed to build a guitar from scratch into a highly playable and tone-laden instrument. I decided to start GJM Guitars to facilitate my desire to design guitars that I could produce to my needs as well as other experienced players. The only way I felt I could get great at fretwork and manufacturing was to find a job working at a guitar factory. That's just what I did. In just a few short years I fretted over 600 guitars and worked side by side with some of the greatest luthiers in the business at the same time.  It is to me one of the most fulfilling endeavors to create instruments that other guitar enthusiasts love and can pursue their passion with one of my creations. 

 

My designs are familiar to true classics but with a twist. I quite enjoy working with Limba and other wood species that are naturally beautiful . I'll either apply a hand rubbed satin gel or high gloss poly as well as offer one of a kind nitro-distressed finishes and other unique finishes such as the aged barn wood and white-washed fence look.  All of my necks feature a 22 fret, 25.5" scale length with a comfortable C-shaped neck profile.

 

I offer two price points; the "Standard " with an aftermarket neck that I fret, level, crown, and polish for maximum comfort. The second is the "Premium" which you can select the woods for necks, fingerboards , and body as well as selection from two neck profiles; chunky and standard C . For the premium level guitar you will also have the option to choose the fret wire as well. Both options will offer selection of body wood type, finish, pickup configuration and pickup model and brand and other features such as tuners, bridge and other hardware options.

 

"Standard" prices are $1899 and "Premium" start at $2499. 

Each and every guitar is hand built by me at my shop in Southern California. I look forward to creating a truly unique guitar for you to enjoy for a lifetime!"
