Rivera KnuckleHead Reverb K55R

Amp 55w lamps (svetlana EL34 original Sovtek 12AX7 original pramp)
Between high, low between.
3 Channel. Clean, Crunch, Lead. Each channel has a boost that increases volume (a little) and gain. (Activated via the pdalier twelve o'clock comes with the head, or any other pdalier noon, or by pressing the gain knobs each channel)
3bandes eq eq for clean and crunch 3bandes common and lead. Of eq knobs on these there are boosts "push-pull". This is not the same as prcdament boosts, these are the boosts of equalization only accessible by pressing the pots read these boosts.
Found on the clean "contour" which boosts the bass (in the fupport knob bass); notch digging the mdiums (knob middle), which accentuates the treble bright (treble knob).
On eq crunch / lead are the same except contour, the amp has plenty of bass.

On the left of a panel of controller found the prsence (emphasizes the high treble) and a "focus". It adds a little grain rivera typical rough by adding also gain, volume and bass.
Each channel has a gain and a knob volume is above those who dterminent the volume of the amp (no volume general).

derrire the amp are: Midi in, out and noon rivera fs9 (MIDI supplies 12v to power the car pdalier twelve o'clock rivera, super convenient).
The effects loop with send and return and an adjustable knob "blend" for the controller% of the loop in the sound. 2 hp output selector with 16ohms April 8, an output to connect a subwoofer Rivera. A selector for dividing the power by two, and a selector modern / vintage reducing the power of two. Both alter the texture of her huh. officially so we can go from 55 25 12w.

I had a 2 knuclehead and I pass on that for the MIDI the three channels, the loop controllable by noon, reverb, etc. so I'm in my lment but ... eq comune MRIT a head shot so I put 9 / 10

UTILIZATION

So it's been a lot of mess, the panel is controlled by long, it gives the impression of having lots of buttons, it's scary to people. I think it's great to have lots of cool rglages possible. And more people take the air "I know nothing oul There's too many buttons" so that when you count y'en see much less than a majority amp! The guitarist seems dbrouillard I say to you ...

The config noon? We had told me from evil "attention rivera for MIDI I understood nothing" super yeah I never touch before MIDI and I put all 4min30s Settings, I find it very simple. The thing is custom settings of the head is fixed so we chose what sends the info pdalier (which is the iVerse of a lot of things so watch twelve o'clock the change There's grannies " oh I'm to old habits francs ..."). Rivera manual (available on the net) has 3 tables (one per channel) or you choose if you want to boost, reverb ... It gives you a numro pdalier that falls within the 6-button presses.

As for the rest I find it so simple, knowing that what I wanted I will not complain, APRS those who like single channel without rglages bah they are a little but Drout well nothing serious.

It gets a good sound easy? L is subjective. I play what I call modern mtal, No. SOMETIMES AND SOMETIMES trash-core thing thing, while having a love of the beautiful clear sound and marshall crunch chantoyant. I prfr sound knucklehead (I'm for the distortion of all, you'll understand) a savage, powerball, screamer, fireball, 5150, XXX, dual front, vh100, JCM900 and 20000 ... brief sound a bit original I liked.
I play with a emg81 LTD, ok the sound is a bit to clear the scratches, but with a strat 'ca pte well.
To me a good sound easily j'obtient yes, APRS is just a matter of loving the grain and make it a little.

SOUNDS

Despite what you read on the forums, so the distortion should mtal my style and yes there is enough gain.
I use it with the baffle rivera 4 * 12 in V30 is a great speaker (other compartment on my own care, I keep baffle)

Quuels j'obtient types of sound?
Big comprss aggressive modern sound with the grain in the high cal mdiums. The low stand of the great amp, as the grain is a bit aggressive as it sounds serious and it will be appaercoit with a microphone in front of the lower spring ca / ​​down mdiums (if desired).
Yes grain is a bit aggressive and not forcment flattering, but in the mix ca slice.
without the boost ca can have another nice crunch.
We can see groups like 30below summer, Coal Chamber, or even play slipknot on it (I was ashamed for a moment and then huh ... lol) and if the guys from slipknot are on a VH4 and a ubershall and take Rivera is not a just for fun.
I was complimented on its disto "I would not know ha rivera, ca ha sounds good in fact", and yes I too thought c'tait amplifier for clear sound hhbr / > So it sounds modern high gain if desired. A grain a little unique. This amp sounds, if he is not cut like all his mdiums 0 dtracteurs do ...
The emg81 are really good on this amp, ca enlve a little grainy cot draft of the amp, for that matter if I played the death I would play on this amp.

The crunch of me really thought marshall (scratches in emg81 on that channel it sounds deftones). It can lead to a gain if you go up, there's margin, even if a little over ca dirty, but it has its charm. Personal I have hardly used without the boost, but it is several reputable really do a lot of bluesy jazzeux apprcient this amp for that channel is not for nothing.

the clean is great, silky, crystalline, if you want, it's not a monster headroom (normal with my emg) but large enough to do.

The focus button makes it possible to smooth to granulate or the grain-General for the amp, for those who like the big grain bin you put it back, or if there is one osn the amricaine VHT will tend to lower it.

The reverb is nice even if I am not a connoisseur. I am very sad not to have dsormais.
The prsence doing its job, it is intuitive.

OVERALL OPINION

I used 1 year.

I do not like?
But why have an eq damn common!?! Especially since the crunch sounds much worse than the lead, suddenly I invested in a looper MIDI and I put two pedals of eq arrengements for all this.
Otherwise it is this small frquence to 6kHz that tickles me in my ears hyperacusis acouphnises who eventually want to change. It's more a health issue after all.

It sounds, but low volume is not the top must be honnte, even with slcteurs going down so-called power 12W AC sends the pure. Trs and low volume contains ca nasal sounds ugly, not at the top to be.
There's the group reserve of power at wide margin. I RPET trs fort just a quarter of the volume, as much as my 2nd gratteu of the era with its dual-sided 100w. Take the 100W version is not anything more that the same output transformer so it's less cool.

SETTING THE turn this amp are intuitive. When you turn the AC mdiums mdiums adds, you can hear it, not as the correct eh 'ha thee the blow mdiums? Ha j'tait confident that once had you serious "lol.

What I like most is its sound and versatility. In addition to my own silent blue

Quality price ratio? Hard to give an average new prices so hard to give an opinion. Disont that is fitted to the teeth and the sound is good, so it's cool. APRS is on the options and you pay the price can be There's way to get better ... otherwise lean toward the KHII.

With the experience I sold this amp for a Bogner ubershall ... I would regret it one day but I wanted to change.

I suggest you try this amp before buying it. Do not rely on samples Rivera or others, it rings true Difres any micro that I have screwed up before dforment grain. It is discoverable to the 1600th, ca does not hurt.
