Hartke presents the HD508 Bass Combo Amplifier. This 500-watt beast of an amp is perfect for the gigging bassist looking for a combo amp that is both powerful and portable. Featuring Hartke's HyDrive design and a selectable shape circuit, the Hartke HD508 is a true workhorse and a great addition to Hartke's popular HD Series.

Powerful and Portable
The Hartke HD508 features four 8" speakers and a lightweight Class D amplifier that produces a whopping 500 watts of power. This 49-pound combo amp is capable of filling any rehearsal space, recording studio or performance venue with ease.

HyDrive Design
The HyDrive series features Hartke's famous paper/aluminum hybrid cone drivers. These speakers deliver an exceptional blend of warmth and attack that can't be attained by traditional all-paper bass speakers. The HD508 packs four 8" HyDrive speakers into a single cabinet, creating a combined cone area that is larger than that of a single 15" speaker.

Selectable Shape Circuit
Dial in a specialized EQ curve with the HD508's selectable Shape circuit. Designed to improve your tone through selective boosts and cuts across the frequency range, the Shape circuit in combination with a 3-band EQ allows players to find a customized tone all their own.
