Castilla guitars were economical guitars manufactured in China in the 1970s for C. Bruno & Sons, a musical instrument distribution company owned by KMC Music, Incorporated. Most of the Castilla guitars featured nylon strings and basic, no-frills designs manufactured with inexpensive materials.
In addition to the Castilla acoustic, bass and electric guitars, the product line also featured banjos and mandolins. In 1976, the Castilla Kopy Kat series was introduced. It featured nearly direct knock-off versions of the popular Fender and Gibson guitars.
As of 2014, Castilla guitars can still be purchased through private sellers locally, on retail sites such as eBay or through independent musical instrument dealers.
