Ashdown Engineering is a British manufacturer of instrument amplifiers, particularly for bass, and one range of guitar amps.
The company was founded in 1997 by Mark Gooday, a chief engineer and manager at Trace Elliot. The company suffered large financial losses, and Gooday was fired by Trace Elliot's then parent company, Kaman. However, he had secretly been planning to start his own company. The company was named 'Ashdown' after Gooday's wife's family name, and the logo was constructed from this, the Austin-Healey motor badge, and Mark's insistence on the use of the word 'engineering'.
Ashdown have gone on to produce hand-wired amplifiers, and set up a separate company called Hayden who also produce hand-wired amplifiers.
