The HD75 (75 watt, 12" driver, 1" tweeter) features Hartke's patented HyDrive speaker technology, which offers a meticulously crafted hybrid (half paper, half aluminum) cone bass speaker. Combining the warmth and roundness of paper with the punch and attack of aluminum, the HyDrive design produces a serious tone ideal for bassists of all genres and styles.

Packed with professional features, the HD75 combo is designed to be easy to use and reliable for players of all levels. The combo offers volume, bass, mid, and treble controls on its top-mounted amp panel, as well as a 7-band graphic EQ for easy tweaking. It features a full effects loop, as well as a 1/8" stereo auxiliary input for playing along with your favorite tunes via an MP3 player, and a 1⁄4" headphone output for more intimate practice sessions. In addition, the HD75 features a built-in limiter to keep the amp running at safe levels. Finally, its rugged enclosure is stylishly finished with a sleek, perforated metal grille and molded strap carry handle. With the exceptional sound of HyDrive speakers in a durable, highly portable enclosure, the Hartke HD75 bass combo is able to perform at levels far beyond ordinary bass combos.
