Preamptive The TX300 preamp features an active 3-band EQ with Hartke’s Shape circuitry for tremendous control over tone. The Drive control allows users to add subtle warmth to their tone or crank it up to full fuzz. The onboard compressor can be dialed up to even out note volume, add punch, and protect the speaker cabinet from the harshest finger-popping techniques. In Shape The Shape control is a contour filtering system designed to enhance the sound of bass instruments. When enabled, it allows the player to continuously sweep a filter through various frequencies to tailor the effect of the curve to the specific sonic characteristics of their instruments. This curve provides a moderate boost at certain frequencies and a deep cut at others. Light & Versatile Featuring an anodized aluminum chassis and weighing only five pounds, the TX300 is both rugged and ultra-portable. This Class D amplifier delivers the sonic characteristics of traditional amplifiers without the weight. A balanced XLR direct output allows direct connection to a mixer, ideal for direct recording or venue setups. And with a headphone output and 1/8″ (3.5mm) input for playing along with your tracks, the TX300 is equally at home in the practice room, the studio, or on the road.
