Customer ratings for Hartke HD 15

The amp made a great impression, it sounds great, I've always wanted to try Hartke products and I was not disappointed. no cone vibrations or obvious defects. it arrived intact, although the package was handled a bit clumsily by the couriers.
I have only used it at home with a bass guitar with active pickups and the volume is more than adequate for the studio, excellent way to plug in an external audio source to play along.
Thumbs up!

Everything is wonderful. The device is very fine. Sounds great like the HD25 which we also have.
Only the packaging in the box was very dusty.
Please dust off the next time before you put the packaging in the box.

I like a lot this amp and very satisfied with the purchase. It's very straightforward and simple but with this EQ and standard Bass/Mids/Treble knobs, it's possible to get a huge variety of different sounds. It can be used for both, practice and gigs, nothing to compain about this amp at all.

I was looking for something light and smaller than my tower with 4x10" and 1x15" with top.
The HD 500 is exactly what I was looking for. It is light, has enough pressure to play with it even on bigger stages. The EQ is very sensitive to adjust and it takes a bit to find your way around it. Once you have found your setting, the sound and the existing pressure is a real pleasure.
Unfortunately, you can not connect another speaker.
But there is actually everything you need. Enough power and a DI output for a PA system.

I am very satisfied with it.

The workmanship leaves nothing to be desired. Those who miss further features like effect send/return should consider how that would fit in with the price.
The headphones output and the aux input are features that should be emphasized.

The amp is comfortable to transport thanks to handle grips, case handle and wheels.
The equipment is simple, but effective and professional. A gain is not needed and the tone control works efficiently. All important connections are available.
Workmanship flawless and it looks chic.
The amp already sounds to my liking on its own, the tone control only needs to be used discreetly. Fast, direct response and good pressure. Good volume, enough for rehearsals and small gigs. Especially in small rooms, the sound is particularly useful and the small speakers play out their strength.
What I miss is the possibility of connecting an additional box (at 500 watts power), then you could also sound larger events with another box.

good quality at a good price.

I am very surprised about the super sound.
Knakkige deep bass and clear treble.
Even the connected mobile phone is reproduced great.
In any case, a clear purchase decision.

Sick of lugging around, I was looking for a small practice bass amp that is not too heavy and too big, but still brings the low tones loud enough to pass in a small band rehearsal. Tried it out right after unpacking, everything works and it doesn't hum either, as someone wrote elsewhere. The tone control also seems very effective, the controls are grippy and do not wobble. The sample is still pending, because because of COVID nothing goes at the moment, but the volume is certainly sufficient.

Performance of the amplifier ok, getting used to is that you can not regulate inputs separately after the volume, otherwise good sound and good bass

The Hartke HD 75 is a great piece for practicing at home and in the practice room. It can keep up well with drums, moderate electric guitar and even with brass sections and that with a great sound. Only when it comes to the very low tones lacks a little pressure - this may be due to the fact that "only" a 12 "speaker is installed. The frequency response is so balanced that you can play canned music well and even speech and vocals come across properly.

In the meantime, I have exchanged it for the HD 150, but only because I want to use this in larger rooms (1000m ²) and it is no longer much larger and heavier.

I must say that this amp is best suited as a practice amp. In my opinion, it would also be conceivable that he can also hold out for more. Because the power is really impressive for 25 watts.
