Ultimate Performer and Studio Sidekick

The HA2500 offers a host of other advanced features, including tube emulation/solid-state circuitry, a built-in compressor, 10-band graphic EQ, effects loop send and return jacks, and a direct out with ground lift and pre/post switches.

High-pass and low-pass control knobs provide further tone-shaping control over your bass sound. In addition, the HA2500’s protective relay circuitry protects connected speakers from dangerous overloads and prevents “pops” during power-up and power-down.

The Hartke HA2500 is an excellent bass amplifier for live performance in small to mid-sized venues. And with its advanced preamp features, the HA2500 is also ideal for studio work. All of this, combined with exceptional reliability, makes the HA2500 a mainstay in today’s bass industry.
