In this article, we delve into the history and evolution of the 'AC' in Vox AC30/15/10/4, providing a comprehensive understanding of what the 'AC' stands for, and its importance in the world of guitar amplification.

The History of the AC Series

Early Beginnings

In 1962, John Entwistle – the first product manager of VOX Amplifiers (then known as JMI-VOX) – introduced a range of new products that no one had seen before. These groundbreaking amps were labeled with the seemingly cryptic term 'Amplifier Combination'. But what did 'Amplifier Combination' mean?

Definition and Explanation

The term 'Amplifier Combination' in weaponry often refers to a form of melee weapon or projectile weapon (composite) rather than an electrical device. However, when it comes to the context of guitar amplifiers, 'Amplifier Combination' simply means Combination Amp.Let's break it down:

Amplifier: A device that increases the amplitude of a signal. Combination: A blend of two or more different components.

Thus, an 'Amplifier Combination' is a single unit that combines the functions of both an amplifier and a speaker cabinet. This term is particularly significant in the context of Vox amplifiers, as the AC30 is a perfect example of a Combo amp that encompasses a powerful amplifier and a speaker cabinet in one compact unit.
