For instrument sales and music lessons in La Mesa Village, McCrea Music Company at 4730 3rd Street has operated as a sole proprietorship since its 1995 founding. The inventory covers guitars, drums, keyboards, violins, cellos, and trumpets, with in-house repair services that handle restringing, valve work, and reed fitting — a full-service instrument shop that feeds students into the private lesson programs at studios like Moze Guitars. A rental program supplies school-band instruments to students across the Grossmont Union High School District, covering the standard brass, woodwind, and string requirements for beginning through intermediate players. The La Mesa Village location sits within the walkable commercial core along 3rd Street, sharing the neighborhood's entertainment corridor with venues like Coin Haus on nearby Allison Avenue. The repair bench handles saxophone pad replacement, trumpet valve realignment, and full restringing on acoustic and electric guitars using D'Addario, Ernie Ball, and Elixir string sets.
