Big John’s Guitars has been serving the Denton, Texas music community since 2010 under the skilled hands of owner and guitar tech John Oliveira. This specialized repair shop has built its reputation on meticulous fretwork, particularly stainless steel refret jobs that guitarists and bassists seek out for their durability and playability. Oliveira understands that frets are the most critical point of contact on any stringed instrument, and his expertise in both removal and installation sets the shop apart.

Beyond fretwork, Big John’s Guitars offers comprehensive guitar setup services that include truss rod adjustments, intonation fine-tuning, electronics testing and cleaning, and precision nut filing. The shop also specializes in custom wiring modifications for players looking to get more from their instruments. This small operation focuses on quality over quantity, working with what Oliveira calls “an exclusive group of members that are kind, loving and patient.” The personalized attention and technical precision have made Big John’s a trusted name for guitar repair in North Texas, particularly among players who demand professional-grade luthier work and aren’t satisfied with cookie-cutter setups.
