About Ashdown Engineering

The history of Ashdown dates back to 1997, but even in those early days, the company's founder, Mark Gooday, was already considered a veteran of bass amplification. After intense competition with another leading bass amp manufacturer in the UK, Gooday managed to position his company among the biggest, thanks to his pioneering approach, and he set even higher ambitions, developing what this manufacturer is today.
