This is exactly what I needed for a home practice amp.


This works for me as a home practice amp for a 5 string bass. I use it on #2 volume so I am certain it would go quite loud for a small gig. I was concerned about the small 8 inch speaker - being a baby-boomer I would think a bass speaker needs to be 15 inches (or bigger). I was pleasantly surprised to hear the small speaker reproduce the low B string notes.

I'm not the only one who wanted it...


I purchased this based on the reviews, as well as the audio out and the included cable, as I needed to play along with some rehearsal material on my laptop. Now I need to buy another one because.... I was in the closed garage where I live during my lunch break ( I work from home) and within 2 hours it was stolen. Evidently, somebody else wanted it badly enough, because they left more expensive power tools and music gear around it. :s Go HARTKE!

Little amp with a lot of punch!


The Hartke HD25 is a compact but powerful practice amp. It puts out 25 watts of power and has a nice warm tone. The built-in EQ system allows you to shape your sound for added versatility. The auxiliary jack allows you to play over your music of choice and the headphone jack allows you to play and practice in silence. A great value for anyone who wants to get a small bass amp for either practice or small-venue gigs. This is a hands-on product review by Shawn @ Sam Ash Brooklyn.

Great Little Amp


Ultimately, this amp can sound good at any volume, or sound really great if you put some boost and a decent EQ in front of it. This is a real hands on product review from [email protected] Sam Ash Miami

Updated Speaker, updated tone


The HD25 is a great compact practice amp. It is an improvement from Hartke's BA series bass combos in that they updated the speaker to their Hydrive cone. The combination of paper and aluminum provides both warmth and punch at the same time. This amp is ideal for a bass practice amp as it provides just enough power to make some noise without angering others in your house. If you need to be quieter, the headphone jack will allow for private practice. The auxiliary jack will allow you to hook up your mp3 player or phone so you can learn your favorite tunes. The quality of tone and price point of this amp makes it a great value for any bass player looking for a nice practice amp. This is a real hands on review from Max @ Sam Ash Lombard

Hybrid Speaker = New Tone


This amp is great for multiple applications. Fantastic for bedroom practice. The hybrid paper/aluminum speaker cone lends itself to those seeking a fairly modern/contemporary tone. Built like a Hartke- solid. 8" speaker handles all frequencies with clarity and articulation. Great for both active and passive electronics. Do yourself a favor- buy a Hartke.
