Topaz Guitar Repair, now operating as Topaz & Weston Instruments, stands as Nevada’s only Plek-equipped repair facility and the state’s sole authorized Martin Guitar warranty center. Founded by Teresa Topaz, the shop operates within Las Vegas’s only 24/7 climate-controlled guitar repair environment, maintaining the critical 45-55% humidity range that protects instruments from the harsh desert climate.

The shop has built its reputation on precision structural and restoration work, with Topaz serving as one of only three certified Lowden technicians in the United States and the only female tech with that distinction. In 2025, Teresa partnered with luthier Ian Weston from Weston Instruments, combining her restoration artistry with his technical engineering expertise to create an unparalleled guitar tech team.

Beyond standard setups and fretwork, the shop specializes in complex repairs including soundboard cracks, bridge resets, and complete vintage guitar restorations. As authorized service centers for Taylor, Santa Cruz, Guild, Cordoba, and other premium brands, they handle everything from routine maintenance to intricate structural repairs. The facility also welcomes custom guitar builds and services various stringed instruments including bass guitars, mandolins, and ukuleles.
