There was a full range of Castilla classical, acoustic, electric and bass guitars as well as banjos and mandolins. The Castilla Kopy Kat series were straightforward copies of the popular Fender and Gibson electric guitar models.
Castilla guitars were made in Asia (probably Japan) in the mid 1970s for the New York wholesaler C. Bruno & Sons, which in turn was owned by the Kaman Corporation.
