Compact, powerful, affordable

The Harley Benton Block-800B is an affordable bass amplifier head that packs an impressive wealth of features into its compact, lightweight frame. These include a class D, ICE power stage (something usually reserved for much higher-priced models) that delivers an 800-watt output, alongside two speaker twist sockets for connecting external speakers (minimum requirement 4 ohms), an effects loop, a four-band EQ section that allows the user to fine-tune their sound settings, a DI output in XLR format with lift/ground and pre/post switches, a tuner output, and a smart compressor. What is more, the front panel features 3.5mm connections for headphones and mobile devices such as smartphones and MP3 players, perfect for practising after hours. Altogether, the Block-800B thus gives bass players a comprehensive package at a budget-friendly price.

Flexible volume and plenty of headroom

The Harley Benton Block-800B operates with very little noise and provides plenty of clean headroom. Mild breakup is still possible, and any clipping is indicated by an LED on the front panel. Setting all of the amp's controls to the 12 o'clock position will deliver a very clear and neutral-sounding tone, and players can easily dial in their desired sound from there using the four-band EQ. The Block-800B's mute and high-low switches give the user even more control, the latter allowing both active and passive basses to be used. To top it all off, the smart compressor can be activated whenever needed in order to provide compression without loss of volume. The Block 800B's two rear-mounted speaker outputs provide plenty of scope for the user to assemble a bass rig that can make full use of its 800 watts and handle any gig with ease, while the tuner and DI outputs, which can tap the signal either before or after the tone control and compressor via the pre/post switch, will also come in very useful on stage.

One for all

The Harley Benton Block-800B is sure to find favour among price-conscious musicians, whether they are just starting out on the bass guitar and dream of owning a powerful rig with plenty of features or even professional players looking for an easy-to-use second amplifier or a backup for their main amp. Whatever their situation may be, however, the Block-800B is a great choice for anyone looking for a bass amp with a great price-performance ratio. Accordingly, Harley Benton has not cut any corners here in terms of versatility, as is evident from the amp's plentiful headroom and tonal flexibility, and the connections for headphones and external playback devices such as MP3 players and smartphones mean that the Block-800B will also handle home practice sessions just as capably as live performances. And the bottom line: A class D, ICE amplifier has never been this affordable!

About Harley Benton

In addition to an extensive range of stringed instruments, Thomann's house brand also offers a wide choice of amplifiers, speakers, effect pedals, and other accessories.

For the stage, garage, or bedroom

As mentioned above, the Harley Benton Block-800B bass head will be at home in numerous applications. Its auxiliary input options mean that bassists can play along to an entire band via smartphone, while the amp's outstanding portability and DI output mean that spontaneous garage jam sessions will never be a problem, even without a speaker cabinet. This latter option of course allows touring bassists to travel light and saves precious space on small stages. Those who want to go large, on the other hand, will appreciate the two speaker outputs provided, which not only allow the amp to unleash its power on stage but, alongside the DI output, also provide plenty of options in the recording studio, where different speaker cabs can be connected and the DI signal recorded either before or after the EQ section thanks to the pre/post switch.

Signal Amplification

My Humble Opinion

The title is vague huh? Well all I'm saying and this is my Humble opinion. 27+years live performance. Not gonna give you my resume but I have lived a little. Maybe you're like me and saw the stats and the price and here you are. I didn't hesitate to buy for obvious reasons. And they're not getting this one back don't even ask. Thomann backs up their product. The results:
Well, well well, that's where all the power is hiding. In this head.
Sound: there is none, well Kinda. You provide the sound, hehe. This head gets out of the way and delivers sheer power. You will want a pedal preamp in line to shape your tone. That's absolutely fine with me. Preferred by some. Especially these days. This is a smart play by Harley Benton considering all the pre-amps, cabinet simulation, amp simulation out there. Almost all I see these days is one company one up'ing the previous with there AMP, or CAB or FX simulator pedal boards. Thier getting fierce and the quality has never been better. Back to the amp. Here what you get, ALL the power you could ever need for the sound you have in your hands and beneath your feet.
Put your tone in front of this amp and get out of the way. For real. Move, this head is a MAC Truck.
I'm good. Thanks Thomann.


Fantastic cheap little amp!
Shakeyjake 08.01.2022
For the cost this amp cannot be faulted. Plenty of power and volume, more headroom than I think I would ever need. The sound of the amp alone is really quite neutral which I see as a good thing given the choice of pre-amps available now days.
As for the features, the EQ works nicely as you would expect. The compressor is a nice touch that was missing on the smaller Block model. The aux in/headphone out options are great for home practice and of course the DI out is always a useful addition for gig use.
All in all I'm very impressed with this amp, it suits my needs perfectly, seems solid enough and comes in at half the price of what the name brands put out similar products at. Highly recommended.


Great bass amp - loads of power
NigelJ 31.08.2021
This is a great bass amp, especially for the money - I paid around £270 and I think the price is even lower now. I believe these amps use the same class D digital power amp as premium bass amps and it shows. Plenty of headroom and brilliant clear sound. Look no further if you want an excellent, powerful bass amp at a very reasonable price!


Harley Benton needs more quality control.
Votanik 08.01.2024
First, I'd like to mention that I am a guitarist and a producer, not an expert on bass amps, but I do have a good understanding of what constitutes a quality bass sound.

This amplifier exhibited malfunctions straight out of the box, emitting strange crackling sounds, especially during the decay of low notes. Regrettably, this isn't my first experience with receiving a faulty item from Harley Benton upon delivery. Could this be a mere coincidence? Probably not. Consequently, I will think twice before considering any future purchases from this brand.

The amplifier was paired with the matching Harley Benton SolidBass 410T, a 450-watt cabinet. On paper, the amp was supposed to deliver 800 watts at 4 ohms, while the cab operated at 8 ohms. So in my case, the amp's output should have been around 400 watts.

Given my familiarity with 100-watt all tube amp heads for guitars, I anticipated the 400 watts to destroy my rehearsal room. Unfortunately, the 400 watts were barely sufficient to cover a drum set played with medium to hard intensity without triggering the amp's clipping indicator to turn yellow. Don't get me wrong; you can still cover the drums or perform in a small venue with this amp, but it invariably pushes into clipping territory.

Clipping this amp isn't necessarily a bad thing; when the LED is in yellow, you'll hardly hear any distortion—instead, it tends to impart a sense of signal compression. Depending on the musical style, some may find clipping to be a pleasant effect. However, in terms of clean headroom, as I mentioned earlier, this amp barely covers a drum set.

Is this amp truly delivering 800 watts at 4 ohms? Are the watts in solid-state amps different from tube amps? I have no idea, but in terms of volume and clean headroom, my expectations were higher.

The EQ section of the amp is quite musical; you can sculpt most basic bass sounds using the built-in EQ, which is a positive aspect. The compressor is also usable, and the potentiometers provide a satisfying tactile feel when adjusting them. Unfortunately, I can't comment on the amp's other functions due to the malfunction, which discouraged me from exploring the equipment further. Fortunately, the Thomann team approved my request for a return, and I will be sending it back tomorrow.

Had this amp not been malfunctioning, I would have kept it. In terms of sound, it was decent but nothing extraordinary. It could produce a respectable sound suitable for work, and who knows, with the addition of pedals, it might even sound great.

In all likelihood, I'll invest in something slightly more expensive, but I won't be considering Harley Benton. I feel insecure relying on their products for a gig, fearing it might malfunction in the middle of a session.

I need to feel that I own something more reliable for sure.
