Custom Builds

Hand-Made Guitars

We build custom, completely handmade guitars for professional and amateur musicians to their specifications, based on their playing style and preferred sound.

All of our instruments are completely hand carved and shaped in our workshop, using both classic and modern methods of lutherie. Our steel stringed instruments employ pre-war scalloped x-bracing, and we offer a wide variety of tone woods for tops, sides, and backs.

We take pride in providing our customers with guitars that  far surpass the quality of factory-made instruments, each with an individual personality and hundreds of hours of craftsmanship.

Currently, our available models for order are:

Parlor, Orchestra Model, Classical, Dreadnought, Electric, Electric Bass

The process all begins with a conversation, and selection of top, back & side tone wood, neck & fingerboard woods, rosette and bindings, tuning machines, and more.

We only build ten guitars per year, so please contact us to start designing a hand-built guitar of your very own.  We look forward to crafting a guitar that is a perfect fit for you.

About Us


Matt Spampinato founded Spampinato Guitars in 2016 after completing two years of rigorous study with Edward Victor Dick at the Colorado School of Lutherie and Victor Guitars.  Matt is a retired Denver Public School teacher of 25 years, and is the creator of the Thomas Jefferson High School Center for Communication Technology, where he taught subjects as diverse as photojournalism to robotics.  A life-long carpenter, Matt has decided to devote his artistry to building custom, handmade guitars and repairing all varieties of plucked instruments.  “When I’m building and repairing guitars, I feel as if I am adding to the aesthetic inventory of our musical and artistic community; it’s most rewarding to see a musician play one of my instruments and not only experience the satisfaction with my work, but using that guitar or ukulele to entertain others.  It’s rewarding to feel as if a part of me is now part of that performance.”  Now with his nephew Mason on board, who not only brings his natural craftsmanship to the table, but also his professional guitarist’s ear to the process, the two have created a formidable, full service luthier shop.

Mason has always had a close relationship with his Uncle Matt and when he expressed interest in the guitar making field, he never knew it would quickly turn into his passion, and as a team they would make this into a new thriving business. Mason got his start playing guitar and bass and attended The University of Colorado Denver for music performance. Since then, he’s completed dozens of national tours with many bands including one of Denver’s premier groups, Eldren. When he’s not on the road, he loves devoting all his time in the shop learning the ins and outs of lutherie. “After years of devotion to musical performance, and now stepping into the other side and really understanding how to make instruments function to their highest capabilities–as well as building custom instruments to provide the subtleties you just can’t get from big manufacturers–has really become my calling,” said Mason. Having a pro player work on your guitar brings an elevated level to the final quality control process that guarantees proper intonation and playability at the professional level.  Spampinato Guitar customers highly value that extra level of expertise.
