Ashdown Engineering is a British manufacturer of instrument amplifiers, particularly for bass[1] and acoustic guitars.

The company was founded in 1997 by Mark Gooday, a chief engineer and managing director at Trace Elliot.

When Gooday was let go by Trace Elliot's then parent company, Kaman, and prior to Kaman closing the doors to the UK distribution and factory facilities, he had been planning to start his own company.

[3] Initially focusing on bass guitarists, in 2001 the company introduced a line of guitar amplifiers (50W and 100W stacks and combos) called Peacemaker.

[1] Ashdown have gone on to produce hand-wired amplifiers, and set up a separate company for this, called Hayden.
