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.

ROUNDED GAIN STRUCTURE
