With its rich heritage rooted in the history of bass amplification, the B500DR is part of Ampeg’s legendary line-up, ensuring that it meets the high demands of both live performances and studio recordings.

One of the standout features of the B500DR is its robust 500-watt output, which delivers enough power to handle virtually any performance situation.
