All Four Guitars brings Denver’s mountain-inspired craftsmanship to both custom instrument building and professional guitar repair. Founded by luthier Michael Stewart, the shop specializes in instruments inspired by the golden era of acoustic guitar building‚the pre-WWII period between 1897 and 1938. Through meticulous reverse engineering of vintage instruments, Stewart has developed a deep understanding of the tonal characteristics that made these guitars legendary.

While All Four is known for handcrafted custom acoustic builds including dreadnoughts, parlors, and grand concert models, the shop’s boutique approach extends to repair work on both new and vintage instruments. Stewart’s expertise in analyzing historic building techniques translates directly into skilled restoration and setup work that honors traditional craftsmanship. The shop’s commitment to quality materials‚including sustainably-sourced tonewoods‚reflects the same attention to detail applied to every repair job.

For players seeking a luthier who understands vintage guitar work from the ground up, All Four Guitars offers the technical knowledge and hands-on experience that comes from building instruments using time-tested methods. The shop serves Denver’s community of acoustic players who value authentic craftsmanship and historically-informed guitar tech services.
