Antonio Sanchez Guitars is a Spanish classical guitar maker founded in 1984 by luthier Antonio Sanchez, who established his company Concert S.A. in Valencia after years of working in other Spanish guitar workshops and factories. The workshop is located in Paterna, in the Valencia region, where Sanchez and a team of around twenty luthiers build instruments using traditional Spanish construction methods. The company holds OEC certification verifying the Spanish origin of its instruments and has received an export award (1989) and craftsmanship awards (1990 and 1996).

The lineup spans student, intermediate, and concert-level nylon-string classical guitars, with models numbered in series such as the 1008, 1015, and 1030, typically offered with cedar or spruce tops paired with Indian rosewood back and sides. Higher-tier instruments use more selective tonewoods and are personally supervised or built by Antonio Sanchez himself, while the broader catalog covers flamenco models and cutaway/electro-classical variants alongside the traditional concert guitars. The brand is widely distributed through classical guitar specialists in Europe, the UK, and North America, and is regarded as a solid mid-market option among Spanish-built classical guitars.

Antonio Sanchez Guitars has 4 products cataloged on Equipboard, including Classical & Nylon-String Guitars.
