Tom Jennings’ firm Jennings Musical Industries (JMI) had previously marketed the Univox, Vox Amplifier and ‘G-Series’ amplifiers before the company’s first electric guitar amp – the AC2/30 – was developed. 

Appearing in late 1957, this 30-watt 1x12 combo was powered by two EL34s but never went into mass production. At the time, JMI was concentrating its efforts on the 15-watt 1x12 AC1/15 aka AC15, which was successfully released in January 1958.
