hey how can i get my hands on one of the rev series ones do u guys have any in stock?
You need to check out the dealer section of the website to see what the stock is with your nearest dealer. If there is no dealer near you and need some help getting a Rev+ or have specific q’s message us via “Sales” on the Contact section of the site!
Hi! What is the shipping weight of Rev+?
Thanks!
Shipping weight is about 50 lbs.!
Thank you very much!
What’s the warranty on the Rev+? Are their places that service these under warranty throughout the US?
The warranty is a limited lifetime warranty meaning everything is covered for the life of the amp minus common wear items (tubes, fuses, etc.). The warranty is only good for the original owner and does not cover user damage. So basically if a transformer, capacitor, resistor, basically any part that would leave you dead in the water goes wrong we’ll cover it! At the moment we service all amps out of our home shop in Tempe, AZ…
Have you guys noticed any problems running this through non Krank cabs? Just curious because I can’t afford to replace my cab and amp at the same time. Should I start with this amp or go for the rev cab first? I’m running a 100watt solid state head.
Well there’s deff no problem running the Rev+ into other cabs, you’ll just be limited by what the cab can do as our cabs are oversized and better constructed to handle the low end the head can produce. Without knowing what cab you currently are using I would say if I was to prioritize things it would be to get the head first as I know the Rev+ will smoke whatever solid state you’re using then save up for the cab. If you have any in-depth q’s you want to ask me regarding setup you can feel free to hit me up with those q’s via “Artist Relations” on the Contact section of the site!
Can you do some custom changes?I mean black knobs on Rev 1+ or different colors of tolex?I like Ninety80 design,could you make hybrid as put Rev 1+ guts to Ninety80 headshell?Thanx
Yes that kind of look can be done for the Rev+ as an upgrade option…
Can i get a steel finish grille when i buy my rev+ ? also would it cost me extra ?
Yeah you can certainly get a chrome grill for the Rev+ and yes it’s an upcharge of about $75….
hey guys, was wondering if running pre and power amps seperate from the unit would be recommended or required for small club gigs with a rev+ head and cab?
So are you talking about using the effects loop on the head to run the preamp out into a smaller wattage power amp? If so you would still need to be able to put a load across the Rev+’s power section or burn it up! Or are you talking about the opposite, running a preamp into the loop and using the power section? Clarify a little here!
sorry, yeah running a preamp into the loop and utilizing the power section, like a triaxis pre and a 2:90 power.
OK yeah that’s no problem to do that! I’m guessing you’re going to use some type of preamp/processor on smaller gigs to keep the sound levels down….? At any rate yeah you can slave the power section of the amp thru the effects loop, no sweat…
hey again,i was wondering what is the difference between this and the Krankenstein+ head,aside from the obvious lol
Well the difference is the obvious….! LOL! No the Krankenstein+ has a differently voiced clean channel, a little more gain and an overall master volume that directly controls the power section of the amp. When asked “what amp is better?” the real truth of the matter is it’s completely subjective. Some people think they absolutely want a Krankenstein then after all is said and done end up with a Rev, or vice versa! Both are awesome amps!
got that right,played em both absolutely love em both. how is the clean channel voiced differently? to make it sweeter or grittier?
hey, for christmas hopefully i will be getting a rev+, i have a peavy windsor cabinet and i dont have enough money for a new cabinet. i know somebody asked before about using different cabinets but, do you know anything about my cab and can you tell me if it will be okay? also, i have a gibson les paul studio and a guitar with P-90s. les paul should be good, but since its a high gain amp, will i be getting more feedback then guitar sounds with P-90s? just in case, i also asked for a noise suppressor pedal for christmas. thank you for reading my very long question. haha if you did… just kidding. hope you do though.
Hey man no prob answering you! Truthfully I’ve never played that head thru a Peavey cab so I’m not sure what the response of the cab will be. I’m sure our cab would sound much better but just make sure the ohm setting match for the optimal performance of both! As far as the rest of your rig the Les Paul will sound great and really you won’t too much in the way of squealing, at least we don’t here at the shop. The cab will obviously be part of that equation but I think you’ll be good !
yo catero, i got the rev plus and the noise suppressor pedal for christmas. fuck yeah. but i have one problem, maybe im just retarded or something but, when i try to run my boss ns-2 noise suppressor pedal through the send and return on the back of the amp, its just not working. but when i go straight from guitar to pedal to input, it works. maybe im doing something wrong but i feel like a dumbass and hopefully im not insane and there is an explanation for why it isnt working.
Truthfully man just run the noise suppressor in line to your amp! The Rev+ is a very quiet amp on it’s own and it’s usually pedals that will add in any extra noise, placing the noise suppressor in line versus putting it in the loop will probably be the ticket for you. However if you want to use the pedal in the loop 1) make sure the fx loop is engaged and turned up, and 2) make sure you have the cables correctly going to the send and return!
Catero, if you didn’t check out my question on the Krankenstein+ product page, could you please? Thanks.
i dont know if someone said this already but, 4 of the audio samples up there dont work. the 4 samples above the last one. the last one and the top 3 work. just givin you guys the heads up incase im the only one with the cojones to lend a frickin hand around here. haha just playin. but yeah, the samples.
Haha well we’re working on getting them working again!!!!!
hey, i realized that there are about 50,000 comments about the tubes and how they have to be replaced every year and how they are a nightmare, am i really about to be tangled within the darkness of the tubes shadows?
Haha don’t fear the tubes! Yes tubes have to be replaced and can fail on you on occasion but nothing can really replace that sound they produce! Depending on how much you play the amp you won’t need to change tubes that often. On a professional gigging level tubes only need to be replaced probably every six months, on a casual playing schedule tubes could last up to a couple years… You have to use your ears and when you start noticing a sound difference it’s probably time. As far as tubes going bad just kind of remember that you get what you pay for when replacing them, that better brands tend to last longer and be more reliable. With all Kranks the power tubes (which are the most expensive tubes you would have to replace) and quality Sovtek tubes and are extremely reliable! We use Ruby high grade tubes for the preamp and they too are great, long-lasting tubes. You will just have to add an extra measure of care with a tube amp but you will dig the tone!
Both the ‘Rev+ stereo high gain’ and the ‘Rev+ drop tuned stereo high gain’-tracks dont’s seem to work (File not found)…
Trying to get it fixed!!!
whats the diff. between the revolution and the krankenstein? more gain? or what?
More gain and an overall volume control on the power amp section…check some of the other comments as I’ve explained this a couple times to people and you can get that info there!
You guys at krank make one damn fine amp!!! I was surprised to get all the tones out of the rev+ I wanted with the basic set up of the amp. Way more user friendly than some high end triple rectifier amps I looked at. Way better tone also!!! This is deffinately a tone monster. Thanks Krank!!
Muchas gracias muchacho :) Always happy hear from a satisfied player!
Yo I noticed that the following sound samples:
Rev+ Semi Dirty by producer Chuck Alkazian
Rev+ stereo high gain
Rev+ drop tuned stereo high gain
Rev+ clean finger pickin’
Do not work. I think the problem can be solved just through removing them from the website and then reuploading them. Whatever you used to put it on the site just re-doing it should fix the problem. Because the other samples do work so it should be an easy fix.
Dont know if you tried yes or no but it shouldnt be difficult as the other samples do work and those are only the older samples. (But they still just sound kick-ass and I just wanna be able to hear them again)
Can anyone tell me if those samples were taken from actual songs or if they’re just specially made for the sake of having samples. If they are taken from songs. Whats the names of the songs? :P
Thank you
Actually we’re getting those fixed, there’s some sort of glitch there so hang tight…and most of those samples are from songs on albums but truthfully I’ll have to look up what was what haha!
I have to say since I got this head my life has changed.I was looking for that type of distortion for years I`m glad to know that I found it…..Thanx to Krank
Hi Guys,
can you tell me the KRANK Rev Setting in this record?
“Rev+ drop tuned stereo high gain”
and… which microphone you used? How many tracks per guitar are recorded?
Thanks!
Waldemar / Germany
How wide is the rev+, just checking to see if it’ll fit into a flightcase i already own.
The dims on that head are 25 9/16″ wide x 10″ high x 8 3/4″ deep and add an extra 3/4″ to the height if you keep the feet on as well as an additional 3/4″ for the handle…
Hey,
where can I get Rev+ in the UK, the distributor u have on your website seems to be a caraudio company, there’s nothing about Krank Amps there?
cheers
i was just wondering if my diezel cab can handle the rev plus. and if it would sound better than my 6505 plus. thanks
I’m sure your Diezel cab will handle it fine enough. As far as if it will sound better that a 6506+ the answer is most deff YES! Especially if it’s clarity and definition you’re looking for… They’re really not comparable to be honest as the 6505+ is in all reality a mid-price amp. It’s not a bad amp at all but it’s not at the caliber of a Rev+ for those wanting more boutique-natured tone and a wider, more open sounding head. You will totally like it!
i was wondering if the rev jr pro sounds the same as the rev plus. thanks
It’s the same tone stack in the circuit so yes it sounds very similar!
Hey. I have a Krank Rev1 and while I like the amp, I get a certain about of fizz or harshness with a high gain setting and a reasonable volume. If I dime the violume, there is little fizz. Does anyone know of a way to tame the fizziness? I love the actual tone of the amp.
Hmmm fizziness huh? How much presence are you using? High presence levels can cause that somewhat on that particular amp as adding high gain with lots of presence sizzle is certainly a recipe for the fizz. Is this an original Rev btw or the Rev+? And did this just start or has it always done this? If you’re running reasonable levels in the high end and not really doing anything extreme there could be a problem possibly…
I have a Rev+ with rev cab, brand new from musiciansfriend.com a year or two ago. I have running it with a schecter c1 hellraiser and the first couple of months it sound awesome but, then I start noticing a loss in gain and distortion now seems so muddy and quiet. tried with other guitars and removing all the pedals from the signal chain and got the same sound, it doesn’t sound like in those audio clips posted here. I changed two tubes in the preamp, but didn’t notice a big difference. So do you think that the problem come from the power tubes or both or nothing at all? any recommendation? thanks!
If it sounded great to begin with ans then over time started losing gain I would bet you need a full tube replacement versus just the preamps. Tired power tubes can certainly cause what you’re experiencing. If you do that and you still have an issue I would contact the tech department thru the site!
do you still make the 2×12 combo amp and if so were can i go to get information on it?
Yep we still make it! I’ll try and get some info up on the site about them as soon as I can (didn’t realize the combos weren’t up there) but it’s basically the Rev+ or Krankenstein+ in a 2×12 combo form with the shell being all poplar construction and the same speakers as the 4×12 cabs… You can buy them in the Krank online store!
I have a Rev Series 1 with the Chrome grille. Is there any way I can purchase a black grille for it through you guys? And if so how would I go about that?
Absolutely you can right on the online store on the website!
Thanks! do you recommend any other brand of tubes instead of the ones that come with the amp? can I use any kind of power tubes or I need to put strictly 6550?
Hey Arturo no you’re not stuck to just the 6550’s, basically those transformers will take any tube you want. Just know however that if you do changes tubes out, even 6550’s of another brand other than Sovtek, you will have to get the amp rebiased for whatever that tube is…
Hi! Where can i get Krank ravolution + owners manual?
Look in the FAQ section of the website and you can download it there!
Hi
I need the dimensions of the Rev+, as I’d like to buy a flightcase. Despite of my research on the internet and the owners manual, I haven’t found it.
Thanks in advance!
Hi
I posted a question few days ago but I think it was deleted >0
I just bought a Rev+ but I need a flighcase for it …. Which are the dimensions of the head?
Also, regarding the sound and maintenance .. What’s the difference between the 6550 tubes and the KT88 tubes? Do they are the same?
Rock on!
WTF!? My previous comment just showed up!
Looks like my boss is doing her job about the employees who are checking Krank’s website jeje
Hey Eric the dims to the Rev+ are 25 9/16″ x 10″ x 8 3/4″ and add 3/4″ to the height of 10″ for either the feet or handles if you leave those on. As far as the difference between Kt88s and 6550s they are a little similar in that both tubes are aggressive in their output but the KT88s are more powerful. We’ve used both in the amps before and simply liked the 6550s more not to mention the KT88s can be too loud if you can understand what I mean there haha!
Hi again
Thanks for your previous answer, but I have another inquiry. I must setup the Rev+ for the European AC 220W-240W and the 2 fuses:
To set the 220-240 W, the switcher must be in horizontal or vertical position?
About the fuses, I take 2 fuses off and leave the remaining 2? or do I need to change the remaining 2? If yes, which are the specs?
Thanks in advance!
Actually you would push the voltage slider to the position that sits next to the 220-240W label and it will specify on the amp below the ac plug in what fuse should be used. But if you have an more tech questions just hit up the tech dept thru the Contact section of the site!
Just pushing the voltage slider, and the amp will set by itself the fuse? Awesome! Way easy than expected =D
Rock on!
Hey Eric no you still have to replace the fuse as there’s only one slot but it’s super easy to do…
OK! Thanks, I change it on time and now I’m enjoying it =D sounds amazind and really defined.
Krank it all!
I just picked up a Rev+ and its awesome! I justed wanted to know what the settings were on the “stereo high gain” sound clips were. If possible please let me know how the master volume set. Thnks!
Truthfully I’m not sure what those exact settings were for that sample but I can say a good baseline to start off with is Presence at about 6, Sweep around 4, Bass around 6, Mid around 4, Treble around 7, Master 1 or 2 wherever you like for loudness, Gain around 8. Of course you can adjust from there. You’ll find the sound will radically change just by rolling the Sweep around, and that interacts directly with the eq, so there’s a lot of different ways you can change the sound of the amp!
i got a rev+ and it sounds great, but on the lead channel the amp is picking up radio stations.its really anoying. the guitar im running is a esp,ltd eclipse with emg active pickups. im also running a boss noise supressor straight to the amp. i have a diezel cab and ive ran my 6505 through it before and ive never had this problem. so im pritty shure its my rev+. thanks
Well Michael you must be in an area that has some pretty strong radio signals and your problem isn’t unheard of. Often times the wiring in the walls of a room can act as a giant antenna for radio signals, and the amps parts, like that giant transformer made of copper and steel can accentuate those frequencies. Part of the Rev+’s charm is how open and clear sounding it is, the reason for that is in layman’s terms we don’t put extra components that dampens the signal like say the 6505 BUT that same dampening type of effect also makes the 6505 sound muddy and squishy at higher stage volumes. Because the Rev+ is designed open sounding it is the give and take that can occasionally happen with radio signals. And when you couple all that with a guitar with very hot active pickups like EMGs amplifying things even more you have the perfect storm for picking up those signals. I myself experience that at our practice studio at times and only on a very rare occasion at a gig depending on where we’re touring. The only way around that is power conditioning and trying different outlets in the room which can help a lot…
I just bought a second hand Rev1. Knowing the good reputation of these amps I did even bother trying it before purchase… bad thing, when plugged in I found out the amp was producing an horrible SHHHHHH on the Krank channel, no matter what master in use. Any suggestion?
