Some people just don't like this amp. I can see why. The Krank channel doesn't blow your face off with lightning-charged flesh-ripping metal tones with a guitar plugged straight into it and the gain knob at 10. Since most people associate the Krank name with that sound, this amp is a surprise to most people. So if that's what you are looking for, look elsewhere and good luck because you're never going to find it anyway.

What this amp does, though, is amazing if you can recognize the beauty in it's intent. I've owned this amp (Rev 1+) for 6 years now. I will never buy another amp (unless it's the Jr. version of the Rev or Nineteen-80). Yes, the Kleen channel is like everyone says: big, super clean, chimey, articulate, and warm. You will not find this on any other high gain amp (since the Rev1+ would barely qualify for "high gain" status, this is not a surprise). A MXR Dynacomp in front of the Kleen channel really makes it shine.

The Krank channel has everyone miffed. You really need to spend a lot of time with the Sweep knob and EQ settings... especially the MID and HIGH controls to get the overall tone you are looking for. And yes, this amp can get very very bright on the Krank channel if you don't pay attention to the TREBLE, SWEEP and PRESENCE controls. The thing with this amp is the front end of it is very open, with no natural compression, and tons of input headroom. By itself, this has a rather jarring feel and sound to someone used to super ultra squashed amp compression like a Peavey or Bugera.. like nearly every amp has. What this gives you is an amp that roars with an open boldness and dynamic range, but doesn't shred your face to bleeding ribbons of flesh... at least not without pedals... and that's the whole secret to this amp! The open uncompressed front end of this amp responds to pedals unlike any amp I've ever played through. A simple overdrive pedal in front (with the pedal's gain rather lowish (3-5 o'clock), but its output volume cranked to 10) will turn this head into a fire-breathing, roaring crunch machine. Plus, the active FX loop has a 2nd gain knob on the back that can be cranked which helps to unleash the fullness of hell. On my amp's Krank channel, the SWEEP is set fairly low, PRESENCE is fairly low, the LOW, MID and TREBLE are all at about 7 o'clock, plus or minus a tad, and the GAIN is set to 3... yes 3, the knob on the back is at 1 o'clock, the MASTER is set loud, and MASTER 2 is set louder. Has a silky smooth roaring overdrive that responds to right-hand pressure wonderfully. Kicking on the TS9 throws this thing into a shred machine. I use an ISP Decimator at the end of my pedal chain to insure dead silence during pauses (works awesome) and I essentially have a 4 channel amp with the 2 channels and TS9 giving me pure clean, pushed gritty clean, smooth roaring overdrive, and chunkyshred. Add in the MXR Dynacomp and the tones are wide-ranging, and extremely useful... and sound amazing where it counts... when you are playing with other musicians. Nothing sits on a mix like a Krank. Dual Recto? Had one. Sounds kinda cool by yourself but gets lost in the mix (to my ears with me playing). Waste of money if it disappears when everyone starts playing.

Bottom line is, this may not be the most plug-n-play friendly amp out there... but for the money, it's one of the best choices if you want a killer platform for quality pedals, that is if you want to spend some geek-time learning how to unlock its potential.

I purchased this amp and there were a number of issues, one was the transformers came bent!...They had a lean to them because i guess krank cheaped out on crappy tabs. The second issue was the thing got really really hot. Alot hotter than any other amp i played. Third the krank channel is terrible, I get a better metal distortion out of my 30 dollar digitech grunge pedal. One good thing though is the kleen channel, i just dont like the popping noise it makes when you hit the boost. All i got to say to anyone thinking about buying this is dont! The freaking this is 1600 dollars and i wouldnt pay 500 for it. This was in impulse buy for me which led me to selling itfor 1000. I ended up purchasing a bugera 6262 and that thing will eat the krank up anyday of the week. Plus its constructed better and the clean channel is up to par with the krank. Basicly what im trying to say is i wouldnt recommend this head for anyone, its way too expensive and your paying a crapload of money for a piece of crap. Save yourself the aggravation.

    Comments about Krank Revolution REP 120W Tube Guitar Amp Head:

    I love this amp. First of all, a Mesa Triple Rectifier has always been my go-to amp. I've had a 5150 (which I was never been impressed with), used Engl's which have too much muddy saturation, and Marshall heads. I've always kept the Mesa, but I also added a Krank Rev1 to my lineup. I really loved the character of the Rev1, but compared to a Triple Rectifier, it lacked balls. I sold the Rev1 and bought the Rev+, and what a difference it made! The upgraded amp with 6550 Tubes gave the amp the thickness the Rev1 was lacking. In laymen's terms I can summarize it as sounding like a hotrodded JCM800 (Crunch, bite, attack) crossed with a Dual Rectifier (gain, modern sound). The bass is tight and focused, the high mid crunch is fantastic and aggressive. The highs can be too strong, so I recommend the Treble and Presence eq be dialed down a little bit.

    This amp has plenty of power for live gigs. This amp sounds excellent in the recording setting. It sounds better using a cab with Celestion Vintage 30s such as the Mesa Recto Cab, or the Marshall 1960V cab, than with a Krank Cab (which has a very harsh tone).

    The Krank Rev+ is very open sounding, and not overly compressed, like other amps (Peavey, Engl, Bugera, etc). Basically, if you are a sloppy guitarist, this amp isn't forgiving. If you play tightly, then every note in a chord can be heard brilliantly. (For this reason, is why I see why people may not like this amp, as it doesn't mask poor playing like a 5150 does). This amp has plenty of gain on the Krank channel (and mine came with a Krank overdrive pedal) which I used for solo boosts. I mostly play metal. I don't use more than 1 channel, so this amp only having an overdrive, and clean channel is fine for me (I don't need to pay more money for an amp with 4 channels that I will never use). I don't use many effects, so I can't speak to the quality of the effects loop.
    I set my EQ as follows:
    Gain 10 (which is similar to a Mesa gain at 3 O'Clock, or 5150 Gain on 6), but plenty for me (especially if using the Overdrive pedal).
    Bass 9
    Mid 4
    Treble 7
    Presence 6
    Sweep 2.5

    In summary, I think this Krank Rev+ is a great amp, and vast improvement over its predecessor, the Rev1 by leaps and bounds. The Mesa Triple Rectifier is still my #1 favorite amp. However, this amp actually is easier to dial in for studio recording and get a clearer sound than the Mesa, and I've been very happy with its metal tone, in both studio, and home demos. Would recommend.

      Comments about Krank Revolution REP 120W Tube Guitar Amp Head:

      I purchased this amp way back! It's probably been like five years. I've never looked back once I bought the matching cab. Anyone who says this amp doesn't have lows or is sterile should look at their setup! This amp is made so that you can buy the matching cabinet to get the best tone out of the head! I personally went with the more affordable sst cab and it does the job. If you are a true tone freak than you'll see the beauty in this amp. Running this head with any other cabinet is just a fail. Of course your tone will sound bad if you're not running it with the cabs they were meant to be matched with . Also I'd like to say. Any noob who says this amp gives you a bad tone should look into their effects loop. Of course the amp will sound bad if you're running like ten pedals which are most likely not tru bypass. This amp kills Mesas tone. Bottom line if you're looking for an amp that has balls and a lot gain without farting out once you pass mid level on the gain knob than this amp is for you!

      This amp is surprising

      Comments about Krank Revolution REP 120W Tube Guitar Amp Head:

      The sound of this amp is not something you would expect from a company that markets "metal" amps. There is about the same level of gain you would find on a marshall dsl, and the tone is very marshall-esque. it takes a long time to dial in a good tone. However, i decided to go with it. The lack of distortion is quickly fixed by putting a ts9 in front of the amp and the sound is so big and meaty its crazy. the versatility this amp possesses is something else; i could easily be part of a classic rock band with this and never have i heard such GREAT cleans on a high gain amp. in a mix this amp really shines, it is well worth the money they're asking.

      Junk!

      By Polar express

      from pennsylvania

      Comments about Krank Revolution REP 120W Tube Guitar Amp Head:

      Let me start off with the only good thing about this head which is the kleen channel. It's probably one of the best clean channels I've ever heard on a high gain amp. Real sparkling clear and the boost is a great feature on this unit. Unfortunately the krank channel sucks in my opinion. Not good for metal at all and is really trebely no matter how you adjust it. It just sounds like complete crap which you shouldnt come to expect from a 1600 dollar amp. Another problem i had with this amp is the transformers. Theyre so flimsy. Every krank ive ever seen has bent transformers. one jolt of the head during shipping and theyre bent. This has happened to my rev plus head, my cousin and my friends krankensteins, which is completely ridiculous .Another issue i had is the footswitch. The master switch broke after a day use and it wasnt even abused.You can use a marshall mg footswitch for this head which is designed way better and holds up. Another thing to take note of is that everything on there is a cheap sticker its not even printed on and when the unit gets hot they start to peel off and start to loose their white color over time. For such a high priced amp you think they could at least have it printed on the metal. anways over all i would have to pass on ever buying a krank head again. If you got 1600 to spend go with a peavey theyre built solid and they dotn cut corners and throw cheap stuff on them. I have a jsx and a 6505 plus and theyre both solid and sound great. and if you could save an extra 400 just go for a mesa. Most amps are better and constructed more solid. These kranks are deff not road worthy. The only thing kranks got going for them is their cabs. Theyre amazing and can bring the full potential out of any head. But save yourself the aggravation and go with something else theres plent of stuff out there for the same price or less that is of way better quality and is worth your money. This amp should really only cost like 6 or 700.

      This is a two faced beast you are looking at. The cleen chanel is very crisp and clear, but when you put it on the destortion channel prepare to be scorched by its fire-breathing tone, in other words the sound will simply blow you away.

      GREAT AMP BUT NOT WHAT YOU WOULD EXPECT

      By Heavenspunishment

      from New York

      Comments about Krank Revolution REP 120W Tube Guitar Amp Head:

      Let me start off with the positives. The sound quality on this amp is like no other. Even at extremely high volumes the tone is crystal clear on both channels with almost no noise or feedback at all. This amp is also bulit like an aircraft carrier, but it weighs nearly as much as one too. It also has one of the best clean channels I've ever heard on a high gain amp. But I was less than impressed with the lead channel. Sure, it has a heavy "brutal" sounding distortion. But its so loud that its nearly unusable in most situations. And you have to have the volume all the way up for the amp to sound even remotely good. If you are a serious musician I do not suggest this amp. It is great for playing chords if that's all you do. But if you play fast leads, use pitch harmonics, sweep picking, and all that other stuff then this amp is completely useless. The tone is very dry, the amp has little to no sensitivity, which doesn't allow any notes to ring when you play them. You can not palm mute, or it will sound like the amp is off. You can't switch your guitar from lead to rhythm or you won't hear barely anything. This amp is just not what I needed it for, not what I thought it was. No amount of effects or stomp boxes can change it either, believe me. I'm trying to sell this amp actually, I'm going to buy an ENGL Poweball instead. I will probably keep the cabinet though.

      I got one of these scratch 'n dent, and surprisingly it was in perfect condition...it was a return from someone else. It still had it's bad points - when you push in the boost button on the Kleen channel, it would thump so loud that I thought my speakers had been blown. I also didn't find the Sweep control to be very useful...changing it didn't make much of a difference in the sound. The included footswitch is generic looking, with stuck-on labels. Also, it does not come with a manual! For that kind of money, surely they could throw in a manual!! I will advise you all now...this is NOT a bedroom amp. It has to be turned way up before you get anything that resembles the audio clips on the Krank website. I am returning it this week...it's just not what I was expecting it to be. Judge for yourself...

      I've been playing a long time. Had several dozen amps. This has been my best purchase. The longer I own this amp the more I've come to appreciate it. I've been able to coax so many different tones out of it. I would go to say that this amp has the best clean channel of any high gain amp on the market.Do youself a HUGE favour and Buy this amp . You won't have waisted your time and $ like I have to find this gem. BEST AMP on the market to-day.
