The AD200B MK 3 is quite simply one of the purest valve bass amplifiers ever produced, designed on the premise that the best tone often comes from the shortest signal path from guitar to speaker. The classic, uncomplicated design features inputs for both active and passive instruments, with a simple but effective EQ.

With four 6550 output valves pushing 200 Watts of power, the AD200B has a creamy, dynamic low-end with a focused mid-range. The rounded gain structure reveals a wide spectrum of vintage and modern tones, from mellow hues perfect for flatwound strings, through to heavy percussive grind. Whatever the situation, there is no shortage of punch, which is just one of the reasons why the AD200B has appeared on some of the world’s biggest stages.

Short Signal Path

Well thought out design and positioned components allow for some of the cleanest tones from any bass amplifier. Feel the character of your bass guitar and playing style more than any other amplifier.
Rounded Gain Structure

Achieve a wide array of tones – from the vintage tone of Deep Purple to the modern gain of modern bands.
