charlyschoepflin's review (This content has been automatically translated from French)" serious design flaw!"

TC Electronic RH450
Transistor amp ... with 3 presets, compressor, eq 4 band semi para DI output, AES ...
So why this catastrophic view?
See more!


It could not be simpler ...


Good diversity in the sounds, the final touches will be the choice of the associated speakers.
Especially good power into 4 ohms.


I'm bassist for over thirty years and I have tried many brands and models, I had the Mesa 400+ bass, Gallien ...

Since 04/2012 or I bought this head TC, I was very happy, especially weight and portability, but the sound ...
except perhaps the extreme fragility of buttons knobs on the front. (+ the first pedal LC4 command did not work, changed Guarantee)
They break the first pull / disassembly for cleaning the front and then they no longer hold the knobs. (Broken rear claws on almost all buttons, forced to paste) rather means for the "high end".
These buttons much beyond steel chassis, making them very vulnerable, especially for a so-called "nomadic" head!
The most serious is that behind these buttons there is an electronic card that is "cash received by the various efforts these pots too exposed!

So in September 2014, while the two-year warranty is exceeded for about six months, the drama!

Here I turn on the amp and ... more his or so:
rotten sound, but with very random and erratic over the settings of the knobs on the front panel answers ...

After consulting TC for the repair, I Mélisson shipped to Paris.
I just received their repair quote!
€ 273.76 to repair a head two and a half years! which is still € 700 (we can hope some reliability).
I say that it has not undergone any fall, it has not been abused or subjected to intensive tour and it is transported in a padded case, buttons up.

Verdict: the PCBA board, P18301, 1038 MAINBOARD to change ... The card receives the knobs ... Coincidentally ...

BIG design flaws!
If the metal shell was wider, the knobs are simply immune to shocks and stresses, and I think it is possible to design buttons that support the manipulation, even Behringer arrives!

After consulting TC not care! (Expired warranty) not recognized design fault ...
C'mon ...

I am very disappointed with the reliability of the head, however, was also very satisfying for me!

So, I think this will be my last product from TC, this damage is not a good pub!
A wise!

Mouloud Holywood's review (This content has been automatically translated from French)" Amp Aladeen"

TC Electronic RH450
First of all, this notice as a post through an ISP situ Wadia, i respect the wadienne grammar. Pre censorship of the people, the Admiral Aladeen Gnral, watch what words remplacs by Aladeen are.

The RH450 is a class D amp 450 Aladeen ral. It is dot dun Aladeen 3 band, dun dun Aladeen and Aladeen. Laccordeur built-toues recognizes the finely Aladeen which is very convenient.

The connection is very Aladeen.


You plug in the Aladeen Aladeen and any dish, it sounds very clean. If we push a little Aladeen, we get a very nice grain. What is revolutionary, this is that once the Aladeen found can save the pRSET in Aladeen. There are three Aladeen available.

The Aladeen is really easy rgler with Aladeen paramtriques. The Aladeen franais but really is as useless as the vain efforts of Western imprialistes.

The rglages also as Aladeen that Aladeen, we can really move forward accompanied by this amp.


Easily obtained nimporte what dAladeen style, more neutral, no typ. We can highlight Aladeen or Aladeen choice. The Aladeen is still very taken and very Aladeen. Associated with the speakers of the brand, we get a very Aladeen Aladeen.

To say that Aladeen shoots from Ampeg Aladeen is to say that the Wadia enriched secret military quality plutonium. However, as the TC boxes contain Aladeen Celestion, explained the link Ampeg.


Jai test Aladeen., With a myriad of other models. Jai craqu for its large Aladeen, this is to say the quality of Aladeen.

The report Aladeen / Aladeen is extra from the drop Aladeen following the release of the RH750. Second hand, there are vritables Aladeen do.

TC Electronic RH450
Class D amp type "numeric" with a power of 450W for about 4KG. Already, it is huge. But in addition it works fine without baffle. Thus making it also an excellent pre-amp for the studio. the equalization is monstrous efficiency, the compressor is formidable and integrated user presets true comfort on stage. the Tubetone (emulation lamp) is (for me) more anecdotal. Full connectivity is great and paradoxically simple, indeed it manages certain parameter alone as a great. And the low active or passive, it démerde is the same input, same for the impedance of the speaker or the supply voltage. At the rear an excellent preamp output that is because I use a lot: on small stage I'm too lazy to carry the cabinet industry and I therefore direct sound, big on stage, I put my back and baffle as j sends the output sound to the front, and I use it as a recording preamp directly into my sound card. These are characteristics that motivated my choice (size, weight, sound quality, versatility)


Super simple setup (fortunately, I am a musician, not an astronaut, too much button or parameter and I stress). I used the manual function to access the schedule by the shift knob but frankly, by adjusting the compressor, I use it almost not. I find it easy to have a good sound. this amp is a very straight, it fully respects the instrument. It is far from an all-tube Ampeg head, but it is not at all on the same philosophy. I play the instrument very different: an acoustic bass equipped with a sensor david pledge realist, a Lower fender jazz bass special frettless japan from 1986, it is equipped with a passive micro precision and a Jazz and a sandberg fretted with the same config micro but I use mainly actif.Le TC makes it sound either all these instrument.


I think this is an amp that can suit the style of music asset because it actually preserves the characteristic of the instrument that connects. most of the equalization is so effective that we do what we want.


I use it since February 10, 2012 So five months to date. I tried a dozen brands of diverse amp is the only one who rang my bass and my basses as well for that weight. I buy new and I do not regret my purchase. It's expensive, but it's good material I use for everything, amp (with speaker), DI (without cabinet), a mix of both, and pre amp for home recording. it allows me to sculpt my sound in all its configuration and with + or - 4KG I can really rest evaluate the duration of life of the class D amplifier I chose to trust a brand electronic Tc, we'll see.

ChTBoner's review (This content has been automatically translated from French)" Just huge!"

TC Electronic RH450
Transistor amplifier, Class D

450W (800 peak)

SpectraComp (multiband compressor)
4-band parametric EQ
TubeTone (simualation lamps preamplifier and amplifier)
Master Volume
3 Presets
Built-in tuner.

At the front: an input jack, headphone output
On the back: DI output, XLR output for sound card input RC, RC4 pedal input ...


Extremely easy to use.

The equalization is impeccable and precise, no worries about that.
The tube emulation is quite impressive, very warm sound, not even offer a saturation of the most beautiful effect.
The presets are easy to store and changed, we can not more intuitive.

The utility has several knobs that are active in pressing the "Shift":
Gain knob adjustment deveint SpectraComp
The EQ is parametric (ie it manages the frequencies on which it acts by turning the knobs)
The manager becomes a TubeTone volume presets

Pressing Mute the sound cuts, and the LEDs around the knob is a bass tuner. The focus marks the reference and another point comes close to or away from focntion the accuracy. Handy

Finally, we get easily a wide range of sound. The signal is observed, and the spirit of the bass is intact.


In my opinion, does not color the signal at all, it lends itself to all styles without exception.

If it is modern (TC presents him as the receiver 2.0), and thus provides "a default with the full spectrum of bass, but the TubeTone tampering and cutting the treble a bit, we get easily vintage sound interesting?
Basically you do what you want.

I play on Pedullá and Warwick, two bass with a strong personality, and I hear the sound by plugging directly into the sound card are there. It's very nice.


I've had a good week. I have long eyed it, I almost got back on MarkBass, good cam, a bit more accessible hand, when an opportunity presented itself near me OPUR an RH450.

I do not regret it. I will long, simply because we do what we want. It can be taken throughout his saccoche.

Even new, the price / quality ratio is unbeatable, only Markbass is able to compete.

In short, simply excellent.

See doc builder on:


Configuration very simple.

Manuel clear, it is always useful to read to learn some subtlety!

The sound is like dad in mom ;-)


Genre Rock, Hard Rock, no problem to do a big sound, with a real rgal Tubetone it!

Use this time with a Warwick Streamer II 5 strings and strings with a 4, I test alone and with a G-Force in the loop, my ears no significant loss of signal.

It's been a day that I have so for now what I most aprcier is the dynamics of sound, I play less than before and I get better ;-)


One day!

Test and compare with a classic Ampeg SVT-4 Pro + baffle 810 and there are no pictures, I am left with the TC ....

Dj I play a lot of amp and I really won!

What I like most presets, the SpectraComp the Tubetone, dynamics, in short the amp IN GENERAL ...
What I like least, the presets because there are only three cases!

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

TC Electronic RH450
See different doc.
450w into 4ohms is enough.
As with all digital, there is not the coil that weighs 3 tonnes and which emits magnetic fields formidable to the microphones.
The handle on the side is representative of a desire to make CT a practical object and adapted to the bassist.
Can be a little weak on sound speakers, such 2x500watt ;-)


Usage is Simplicime.
formwork is active or passive bass it is doing itself to adapt the input signal.
Then the 4 slices of equalization are perfectly identifiable.
The simulation of "tube" is clean and that it is cut by octave band is super smart.
then after the most:
3 memories, it's so convenient that you wonder why they limited to 3!
the magic touch:
which converts the gain compressor, such as the "tube" is divided by frequency band (5) this gives a compression always clean and balanced. Even if one does not understand compression just listen and turn the knurled knob and choose what suits. Be careful though the perception of compression depends on the overall sound volume (low volume we pay higher compression, you should consider it before you save your setting that will serve you by repeating your muscular drummer, guitarist and your rage.


The sound is incredibly accurate, meaning that if you play rough with a fingering unlikely you will have a sound draft.
The fact that the head (cutting octave bands of compression and the tube) every single sound balance of risk given his admittedly very good, but somewhat uniform regardless of the bassist. to see!
Tried on 5c Ibanez btb 505 nickel mean the absence of good bass ;-)
and Barillon 5c Fretless (Benedetti + sensor Schertler) .... oouuuufff, awesome, that said, I am still under the emotion.
I put 9 / 10 because I fear that soon the whole world have the same sound.


good AC is only 2 weeks .. super
and then the headphone jack, my girlfriend thought it was awesome.
Otherwise, I change my amp about once every 10 years (I have a head ampeg please pro with thousands of lamps in)
so there I hope the TC will keep me long enough.
And no I will not go the option of purchasing a second RebelHead, slightly less than 1000 euros must be a little careful ;-)
For value for money although he saw the prices at scandalité for ampeg heads that I find a little old and outdated (but hey it's the best one with which it is) the TC 450 is worth it.
At this level of high-end head, there is no bad heads merely heads who do not return?
I'm really happy with this RebelHead.

TC Electronic RH450
<span style="font-weight: normal;">

For it features truly impressive and there's already everything you need on the web: (videos have front and back) (description of innovations) (connectors and external features)

4 Kg, 450 W into 4 Ohms minimum. Amplification: Active Power Management ™, Class-D amplifier that allows a performance equal to the return of any amp lamps. For them, the RH450 is a 450W all-tube amp or a transistor amp 800W. With just one speaker in 8 Ohms, so 300W is already enough to play with the 100 W lamp from scratch all thrived.

EQ 4 band semi-para, TubeTone, Gain, Master, compressor, volume preset tuner, mute.
3 presets to save its settings, for me it would have taken at least 5.

So 9 / 10 knowing that everything is very good.</span>

<span style="font-weight: normal;">


Despite the many functions, the configuration of the RH450 is simple and the manual available online in several languages ​​(including French) is accurate (and for once it is useful).
The main functions are accessible: gain with peak indicator, 4-band EQ and TubeTone can sculpt the sound.
By pressing the shift button you can access functions to more advanced: a compressor (which works), setting frequency and volume of EQ presets.
The tuner works continuously, it is as practical as a handheld tuner when it engages the mute mode.
Easily obtained a good sound and the settings are very effective.

After several hours of use, it is always as intuitive. I notice that the race was almost ineffective Master to the first stop. But hey, no one buys a powerful amp to play 1 / 10 volume (or when using the headphone output !)...


Frankly versatile, I got all kinds of sound I was looking for. (Blues, jazz, rock, funk, rhythm'n'blues, reggea), the treble is clear.
I have not managed to find one for his slap right away (in a 1 / 2 H, so little time), but there are many videos with that amp slappeurs. TubeTone allows the sounds or even saturated fats by pushing a little. Without TubeTone was defined sounds great but not really hi-fi: the RH450 is really a small grain.
JazzBass and Corvette $ $ 's proof.

Edit: for the slap, that's it. Try more with Precision: there is serious!


I tested and compared with a stack MarkBass Little Mark Tube for 3 / 4 of an hour. So I tried the MarkBass, of Ashdown, Trace of Eliot, the EBS, SWR, Ampeg's, the EDEN, the Hiwatt, Fender and ...............

I chose the TC as I search the versatility and the head is ultra-versatile and intuitive: I have found many of the sounds I need in seconds. Also the build quality is as good sound quality.
However it is unfortunate to offer only three presets on an amp as versatile.

That's an opinion (a little) more objective than what can be found on the manufacturer's website and in the mags.

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

TC Electronic RH450
What kind of amplification (lamp, transistor ,...)?

Transistor. And yet!

What is the power delivered?

450 W / 4 Ohm

What connection?

Input jack, effects loop (preamp in / out), RCA input for iPod and other players (only going out on sotie headphone), and output: di out (pre or post switch with preamp), a digital output for recording, and a headphone output with integrated speaker simulation.

What are the settings, the effects? ...

Gain (with clip lights to determine the highest possible input, ultra-convenient), bass, low mid, high mid, treble, Tubetone (simulator lamp, the higher you go, the more the sound is distinctive and warm up to saturation), and master. Once the "shift" under way, there is a compressor, the frequency setting in the center of each tone control, and the preset level, since it can store up to 3.

I put 8 as some little extras for bassists boring (given the quality of this amp is its public!) As a parallel effects loop with mix mix effects were not bad at all!


The configuration is it simple?

Relatively yes, no more settings than enough, with sufficient modulation possibilities for fans like me to hack.

Do you get a good sound easy?

Very easily, the frequencies are already very well selected for each tone control. And since we can change them, there&#39;s something for everyone ... The compressor that is managed via a single knob with an LED indicating the level of compression and gain compensation, ultra convenient!

The manual is clear and sufficient? ...

Very, but given the simplicity of this amp ...
I put 8 as the switch option sold is quite expensive, and it would have been nice to be provided with the amp head (which is already in the 1000 euros!)


Right for your style of music?

Well as any other style. Precise, and very hot when you want. What more?
For me the style of my group ranges from pop, rock, metal and a little funky side

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

Cort Artisan A4 Fretless and Fender Deluxe Active Precision Mexican.
Since I use this amp, I do not play as the cort: the fender is actually much more punchy, but also messy when the cort is ultra precise. And this amp is great out the character of the bass on which we play is striking.

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

For me, slamming and very accurate, but rather dug up in the medium, and boosted by the Tubetone for a more aggressive side, without going to the point of saturation.

What are the sounds you prefer, you hate?

I tested all kinds of sounds, medium grain finger typed Pastorius in his heavy metal and dug through the rock in English incisive mediator and of course its a slap impeccable, I do everything on this amp.


How long have you use it?

It&#39;ll be a month now.

What is so special that you like most and least?

Already, transportation. The head amp in my journey EASTPACK!
Then questions sounds, it&#39;s just the best of what I&#39;ve heard so far.
It is also the amp has on me again love my bass pod (see my opinion on the live bass pod XRT <a title="bass pod xt live" href=""> Live / opinions /</a> ), which I can now make monstrous sounds of this amp.

Have you tried many other models before buying it?

I&#39;m live on some markbass, an Ashdown, &#39;ampeg course, Hartke, Fender, Gallien Krueger ....
And I was so far in Gallien Krueger combo, best of all those I&#39;ve experienced.
The TC has all blown <img class="smiley" src="" alt="mrgreen" />

How would you rate the quality / price?

Expensive, but not in more for a amp of this quality there is doing it for 1500 euros for the entire head + 1 speaker (the 212 for me). Soon 500 more to baffle January 2, 2000 or in total. There&#39;s less and less good and more expensive and not necessarily better. Especially since TC has just released a head a little cheaper repeating the same principle but with a few less features (presets, center frequency, and I know too)

With experience, you do again this choice? ...

Again! The 9 is for all the little details that are missing mentioned above.
