Bass Amplifier

600 Watts at Your Fingertips.

Never comprising tone, the Hartke TX600 merges a classic tube preamp section with modern lightweight, Class D amplifier technology. This combination yields a bass amplifier with the warmth and character of a traditional amp, not to mention 600 watts of power, in a ultra-portable enclosure weighing only seven pounds. The TX600 was designed for performance, and you'll quickly find how easily and effectively it performs.

  • Tone Stack

    In the tradition of the Hartke LH Series Bass Amplifiers, the TX600 features a passive tone stack equalizer section. In addition to a Treble and Bass EQ, the TX600 provides Shape and Frequency knobs to control the mids. The Frequency knob is a sweepable filter from 200–800Hz, while the Shape knob sets the depth of the filter. The amp's Brite switch adds a lift to the high frequencies, and is interactive with the Gain control. As you turn the Gain knob up, the overall effect of the high frequency lift is reduced.

  • Complete Control

    The TX600's front-panel Compressor knob effects the amount of compression by adjusting the threshold level to control the overall dynamic range. This bi-color, backlit knob gives you instant feedback as to when the compressor is active. The TX600 also includes a 1/8" (3.5mm) Aux input, and a 1/8" (3.5mm) headphone output which also mutes the speaker output.

  • Transporter

    The TX600's rear panel includes a 1/4" and twist-and-lock speaker jack, an effects loop and XLR direct output. Its anodized aluminum chassis and integrated handle make the TX600 road-ready for any gig. At home, in the studio or in a practice space, the TX600 will be more than just your amplifier... it will be an extension of your instrument.
