Tempo

Tempo was a brand name of Merson of New York City, who advertised the first Tempo archtop electric guitar in 1948 with a matching Tempo amplifier. Merson was taken over by (or merged with) Unicord in the 1960s but continued to distribute Tempo guitars, amplifiers and other instruments including ukuleles and banjos. The Tempo brand appears to have been discontinued by 1975.
