MGR/Grahame Clayton ( The Rumble Band) www.rumbleb's review"EBS HD350 Rackmount Bass Head"

I bought this amp & an EBS 410 cab after hearing it demonstrated at Music Live2002 on the GB Guitars stand. Head & cab cost around £1200 for the pair. The sound that this combination produces, is far & away the best I have ever heard, and I have tried a lot of gear over 30 years of bass playing.(Marshall, Trace, Fender).

The clarity of tone, absolutely endless volume, loads of punch and not a hint of stress from the speakers even at the lowest frequencies. This unit is easy to set up & use. You can get a great sound 'straight out of the box', and with a little time & the odd tweak here & there, you can soon get your ideal sound. I played through this rig & then played through my (then) existing rig using the same guitar, and I swear I could not believe my ears. My old rig (which I thought sounded OK!) sounded like a muffled wall of mushiness compared to the EBS. Try it for yourself!

There really is nothing to dislike about this rig. As EBS say, built by bass players for bass players. The manual that comes with the head is easy to follow & understand, the controls are well laid out & functional. One tiny downer is that it could use some backlighting of the controls for ease of operation in dark /low light situations, but I have a tuner mounted above my amp head that has a downlighter on it anyway, so I'm OK.

Construction & build quality are first class as you would expect from the Country that brought you Volvo & Saab! The unit is very robust, and once mounted in its rack housing, does not give any cause for concern.

Quite simply, if you are a serious gigging musician & can afford EBS equipment, don't waste time trying anything else. I thought I'd heard everything until I heard the sounds coming from this rig. OK so you've never heard of EBS & your mate says Trace/Ampeg/SWR/Ashdown/Marshall is better. Let your ears decide! Put an EBS rig up against any of these and you'll want one. I know! I did it!

EBS HD 350 this amp does not work with lamps or with transistors, but with a simulator lamps. It dlivre a power of 350 Watts.
The head can be connected with cables or Speakon jacks!
You have a gain knob, a compressor, bass, mdium, frquence of mid, high, gloss, drive (set the effect of simulator lamps, more or less important!), Volume gnral .
More a character button, bypass, a transplant from the head to a sound system, and several other CHARACTERISTICS the back of the head.


Easy to use and set up, you get fast enough that it sounds DSIR with this head. It is not necessary to be an experienced bass player to get the sound that was in the head. However, we should not spend a few hsiter after noon to learn to know the head and what you can get.
The manual is clear, with very Retailer schmas, not very large and will has the essentials.


I use this head with two boxes of 2 * 10 in the EBS to play Rock, Jazz Rock, Jazz, Funk .... It's perfect these styles of music. It was unfortunate at times the lack of real lights to play rock. The sound is more "hot".
I use a Marcus Miller Jazz Bass F Bass BN5 and Custom on this amp, can be said that the 5th string perfectly clear that the amp runs perfectly the overkill of the two preamps.
I love that sound very focused medium that is made out of the HD350. Great clarity of sound, a cot a bit too robotic when you want to sound warm. But otherwise great!


I use this head for a year now, It took me about 2 months to learn to use it properly (I am still very slow!).
I love everything about this head except this little cot his robotic, lacking a little heat.
I try heads SWR, Eden ,...... But this one is my favorite.
The report price is very good quality over the conccurents, a great amp for not too expensive!
If I had to reselect, I repeat the same. Unless I had to play only the rock, I will choose the head EBS Fafner TD or 650 lamps.

Ingmar's review (This content has been automatically translated from French)

SPECIFICATIONS for all is said dj!


I found my sound in 15 Seconds, The compressor is DiscT lamps and simulation simulates well!


I like the funk but I also play blues / rock to time, the HD350 is pretty boilerplate, I use a EBS410 and several low, check my profile! It makes even if well slap ca serves more as often as in time: p I sometimes hear that EBS is too crystalline, too hifi, too aggressive .... it is sufficient to lower the tweeter or treble cut it?!? I also have a Fafner and I can make it sound like any Ampeg, but I've never seen an SVT sound like an EBS ...


I've had six months, I used to rptitions on scne I use the Fafner, but sometimes I prfrer the HD350 sometimes it sounds great too and RULES is easier than the Fafner.

Still, EBS is expensive, but I went through a lot of amps and I finally rest on EBS for 5 years now, and I'm not prt change.

- What kind of amplification (lamp, transistor ,...)?

Any transistor amp

- What is the power dlivre?

350W RMS into 4 ohms

Neutrik connectors for speaker cabinets.

At rglages:
- Gain of with diode Exceeds Level
- Compressor with LED status compression
- EQ bass, mid range with adjustable frequency drives, acute
- Bright (adds clarity)
- Drive (color of its type lamps)
- Volume gnral
I put 9 because it can always be better even if it's not bad dj!


- The configuration is it simple?

No need to notice ... that's all bte.

- Gets it easy to sound good?

Very easy ... the sound wonderful on this amp and has a dynamic of crazy

- The manual is clear and sufficient? ...

I have not even been with when I bought it and I'm all about the EBS website for download and in the end is it for nothing: p y 'are not needed. Maybe just the type prrglages based styles that can guide the rglages but hey it is not essential.


- Is it your style of music?

Compltement. It should all styles elsewhere. the rglages are so effective that I play a little bit of everything on it. Punk Rock, Reggae, Mtal, Funk etc ...

- With what (s) guitar (s) / low (s) or effect (s) do you play?

Warwick Corvette Double Buck.

- What kind of sound you get and with what rglages ("crystalline", "bold ",....)?

The sound of the bass is perfectly Redfin. The grain SPECIFICATIONS my bass amp perfectly clear on this. you can have a heavy and well as having a fat sound with great dynamics and a beautiful slap in Treble ...

- What are the sounds you prfrez, you dtest?

I like everything ... The sound is perfect! No breath, no distortions parasites, nothing wrong.


- How long have you use it?

6 months

- What is the particular feature you like best and least?

What I like most is the typical sound EBS. You have to hear to understand ... I chose this because everything MODEL transistor and ultimately Fafner not need to have a good sound ... At least it's not fragile and there's no maintenance (for lamps)

- Have you tried many other models before acqurir?

I am all in-store without any ide prcise the amp I wanted. I test the Ampeg, Ashdown, Hartke, and EBS Markbass ... and it's love at first sight ... the price was a little cold at beginners, but I put cot for me to buy it because it is really what I wanted.

- How do you report qualitprix?

euros for 1100 is a superb header. It's the same price as a SVT3 (quite rpendu) and frankly the test as you may be surprised even in the face of ampeg!

- With the exprience, you do again this choice? ...

Yes no problem. I love my config (I have no baffle 410 of EBS - I left a review also) and I'm not ready to change! except for the EBS!
I put in 9 overall because there are necessarily better but it's great dj gear!
