Ashdown ABM 600 DR Evo IV Head

Designed and built with love, the ABM 600 Dual VU rackmount head is road-ready. The 3U steel rack chassis with 2 mm thickness features front and rear supports for easy rack mounting and protection on the road. Two VU meters allow you to monitor input gain and output level.

The variable valve drive section of the preamp has been enhanced in the EVO IV version. By supplying more current to the 12AX7 tube, it achieves greater dynamics and harmonic content, enabling the bassist to transition from pure tone to the richest and most full-bodied bass overdrive available today. The Drive level can be preset and toggled on or off via a footswitch, providing access to a wide range of bright, warm, and saturated sounds.

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 electric bass amplifier manufacturer in the UK, Gooday managed to establish his company among the largest, thanks to its pioneering approach, and focused on even higher aspirations, developing what this manufacturer is today.
