Ace Electronic Industries Inc., or Ace Tone, was a manufacturer of electronic musical instruments, including electronic organs, analogue drum machines, and electronic drums, as well as amplifiers and effects pedals. Founded in 1960 by Ikutaro Kakehashi with an investment by Sakata Shokai, Ace Tone can be considered an early incarnation of the Roland Corporation, which was also founded by Kakehashi.^[1] Ace Tone began manufacturing amplifiers in 1963.^[1]

Ikutaro Kakehashi began learning practical mechanical engineering as a teenager, and found there was a demand for electronics repair in Japan following the end of World War II. After recovering from tuberculosis in 1954, he opened a goods store in Osaka and began assembling and repairing radios.^[2] He attempted to build an electric organ in the late 1950s from spares, including parts of an old reed organ, telephones and electronic components, and started a business in 1960, initially making amplifiers. He subsequently designed an organ that was sold by Matsushita.^[3]

In 1964, Kakehashi designed his first hand playing electronic drum, the R1 Rhythm Ace, constructed from transistor circuitry. It was designed to be attached below the manuals on a home organ, and had six buttons that created a variety of percussion sounds. It was presented at that year's NAMM Show. However, it lacked automatic accompaniment and so was unsuccessful.^[3]

In 1965, Ace Tone established a US distribution agreement with Sorkin. In 1967, the company introduced the Rhythm Ace FR-1, which allowed a variety of automatically-played popular rhythms with a variable tempo. It was commercially successful and led to partnership with the Hammond Organ Company, who added Ace Tone's rhythm units to its range of instruments.^[3] At the end of the 1960s, Ace Tone began manufacturing guitar effects boxes, such as fuzz which was modelled on an earlier Gibson model.^[4]
