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.

I could front on a marshall stack witcompact but powerful sound!



A versatile amp


I was under a deadline to get an amp, so I went to the local Sam Ash in hopes they would have something reasonable in stock. The store just reopened after the Covid-19 closure, so my fingers were crossed. They had this on sale so I scooped it up. I like the 4x8 configuration as it's a unique combination. I have used it in a few low volume situations so far and it is easy to dial in a appropriate sound. I hope to use it more once all the Covid-ness is behind me and shows start back up. Until then I will just practice a lot!



Just What This Bassist Wanted


Wonderful! Excellent sound...have used it in various situations...and it's perfect for what I do...church...small venues...outdoor activities...studio...easy to move around and carry...a satisfied customer!





Just using this as a backup amp right now but so far playing around with it it's just what I wanted nice clean sound and definitely loud enough very satisfied thank you Sam Ash



Sam Ash and Hartke: Perfect Together


Unbelievable sound and quality. This combo amp really performs. When set at half volume, will hang with a controlled drummer with no problems. It's so clean. Couldn't be happier. Sam Ash delivered within two days. Under current conditions, that is amazing.



Exactly what I was hoping for!


Like most musicians the older I get the more I want to downsize my setup. After doing a lot of research this amp seemed to be what I was looking for. Lightweight, compact, great sound, and affordable. The only thing I was afraid of is that it wouldn't be loud enough in a full band setting with no mic setup. But I took a chance and bought it and it was exactly what I was hoping for! I play in a metal band so as you can imagine we are pretty loud and this amp was more than loud enough! The loudest I had to go on the volume knob was about 5 1/2. So for the price, the sound, and the weight, I would highly recommend this amp for purchase.





Great amp plenty of head room.Lots of bass.Light weight. Just a great amp Hartke you've done it again!! I have a XL215 HA3500 & VX410. A customer for life!!!



This one's a keeper!


I play bass in my church's worship team band, and I'm very happy with the HD508 Combo. Most of the songs we play are Young Adult/Urban Contemporary, and the 508 handles them well. It sounds great and provides just the right amount of bottom for the room and stage. It's easy to transport, easy to use, and the built-in direct out makes hooking into the house a breeze. You might need more power for larger venues, but the 508 is perfect for most rooms. There's really nothing I don't like about it. Definitely get one!
