Orange AD200B MK3

The Orange AD200B MK3 is a 200-watt all-tube bass amplifier head powered by four KT88 tubes, delivering massive clean headroom and the warm, round low-end character that has made Orange a standard in heavy rock bass amplification. Its simple two-knob EQ and gain structure produce a full, authoritative bass tone that maintains definition even at extreme volumes. Chris Ballew of the Presidents of the United States of America used the Orange AD200B to amplify his two-string basitar, the amp's high headroom and clean low-end response providing the foundation for the band's unconventional low-end approach. The AD200B's tube-driven power section adds natural compression and harmonic warmth that solid-state bass amplifiers cannot replicate. Its Class A/B output stage and choke-filtered power supply contribute to a tight, controlled response that keeps bass notes articulate in dense band mixes.
