- acoustic guitars
Kel Kroydon was appeared as a budget line made Gibson around 1929 but was discontinued by 1931. These cheaper brands like Kalamazoo and Recording King were introduced to help Gibson though the depression when more expensive intstruments would have been unaffordable. There were Kel Kroydon guitars, banjos and mandolins, the first of which appeared in 1929 with the KK line of acoustic guitars. The KK-1, the KK-2 and KK-3 guitars, along with a KK-11 banjo, appeared in 1930, with the banjos and the KK acoustic line again in 1931, with the KK-1 listed as a tenor guitar. Gibson discontinued the brand after 1931. The Kel Kroydon KK1 acoustic is favoured by finger-style players, being the equal of a 1930, 12-fret Gibson L1 but without the adjustable truss rod.
