Very dissapointed with reliability of Kemper on the road !

  • I don't mean to be critical of Kemper at all, but from reading forums and from personal experience, the Kemper does seem to have a very slightly higher incidence of failure than other similar products I've seen. It's not really fair to compare Kemper reliability to tube amps, tube amps will always fail more as tubes are very fragile and amps are always taking a beating, plus new build tubes are not as rugged as the ones made in the 60s/70s.


    Some of the Kemper failures I've read about are: the early LED issue, and distortion developing in the output circuitry, among a few other things. The first Kemper I had was a factory refurb model, and out of the box it had an intermittent distortion problem that required a return. But the replacement for that one (a new in box unit, not a refurb) has worked perfectly. From personal experience I have found Kemper's customer service to be outstanding in every way.


    All that being said, the Kemper is a marvelously well engineered piece of gear, at least to my eyes (I have over 30 years of experience in engineering and manufacturing portable test equipment, so I work with this kind of thing daily). With all I've seen, I would not worry about field failures if the Kemper is treated with respect and its power is kept clean and well regulated. But you always need some sort of backup on a gig because any piece of gear can fail. And Kemper's excellent customer service and generous warranty should put your mind at ease, as much as it can being you are depending on a human built piece of equipment.

  • Sorry to hear of your misfortune :(


    Just hearing of someone else having to play without their Kemper gave me the chills .... the thought is simply horrifying!


    I would say this about amp failures though. You guys have to admit, real tube amps fail with a flare (fire, smoke, boom, pop...... ) that the Kemper will never equal :) So I guess the Kemper isn't EXACTLY like a tube amp after all.


    Seriously though, I have gigged with tube amps for the last 30+ years. Between the amp and the pedal board, the failures were many over that time (even one fire). I would say that the Kemper is at least as reliable as any rig I have ever used.


    While I could make it through the night with my HRD and a couple of pedals, I wouldn't be happy doing it.

  • Yes maybe , but what I meant was a tube I could fix within a few days, tubes, resistors , caps...etc and continue my gig!! The kemper I could if I had the parts available but I don't and I have to send it in and they told me it will be a problem to ship back so this means no kemper for this tour !!!

  • No one should gig or tour w/o a backup of some kind.


    Some buy 2 Kempers for that reason. But there are cheapie alternatives that will do in a pinch. i.e. HD500 or something.


    Trust me, the crowd won't notice. It's proven alcohol kills your hearing ability and non-amp-lovers are really looking at your chops, not your tone. Most people just look at the singer. Come to think of it, bring a backup very good looking singer and stand behind the drummer with you HD500, haha.

  • It's an awesome box of tricks...but, I never had the guts to take it out on a gig, only used for recording and rehearsals. My Marshall JMD102 was my final rehearsal choice due to being more reliable. It was during rehearsals that bugs presented themselves like sound cutting-out completely, tuner activation, volume drops etc that put me off. This was 1 1/2yrs ago though.

    I am surprised that no one mentioned using a voltage UPS stabiliser / regulator / spike remover like used on other computing equipment when its out on the road? (Maybe I missed it?). Lets face it, the Kemper is a computer and all those chips ARE sensitive to spikes and bad variable voltages even with the Kemper internal bits to help stop it... especially when on tour in some countries. I have seen crashing of the Kemper through that sort of thing and using one of those devices that is a uninterruptable power supply does help. They cost really little money and will often resolve that sort of thing. Just thought I would mention it.

    Careful I'm watching you...

  • At home I'm using a Tripp-Lite protector that stops working once it's used up.


    These surge protectors don't work indefinitely . They are rated for a certain number of Joules and when used up, it stops working. So if one is rated for 1000 joules, the unit can take one 1000 joule hit or ten 100 joule hits and then it's used up.


    Some units (like the Tripp-Lite) won't allow any voltage to pass when they stop working. Others do but have an indicator light that they stopped being a useful surge protector. Others don't do any of the above. So investigate the right one for you.


    IDK if the Kemper needs a voltage regulator or not. Maybe Kemper can answer this? There is a raging debate whether most modern electronic equipment need voltage regulation, most already having it, and whether it's just another expensive rip-off. IDK enough about the issue myself. Just read about the debate.


    Which brings up an interesting point . Anyone manufacture a green lightning bolt for the Kemper? If not, I'll go halfseys with a potential business partner. Maybe Zappledan. He's closer to the clouds.

  • I'm 58 years old played guitar all my life and owned a lot guitar amps and guitars.
    I bought my first Kemper Power Rack 3 years back and bought a second one two years ago to have a back up for my life gigs, never needed it .
    At first I allways took it with me and kept it in my car incase I needed it, but last year I kept it at home, my first Kemper didn't let me down so why worry?
    Allways played tube amps and still own a Bogner Shiva 20th Anniversary with special el34 tubes, its collecting dust the last 3 years, so that should give a hint what the Kemper does to me ;)
    The only thing I regret and I'am dissapointing about is the fact that I'm allmost 60 years old and Kemper came up with profiling amps when I turned 57 !, where whas Kemper when I whas young !! ;)

    I am 65 - I do have same question ;)
    It's really the most existing gear I ever had in the last 45 years.

  • You guys can't know how much I miss the Kemper . My gig is kinda ruined because of this, what I have is passable but it's bleh . I've even had a few guitar players come up to me saying I had a killer tone! But I find it crappy compared to what I know I could have !


    I managed to get something workable, I have 3 defective amps which I'm using to get a sound. Pre is a fender mustang 3 , kinda like a bad pod, goin to a non tube fender power amp, because the amp part of the mustang is not working, so I'm using the power section of another Fender feeding a fender hot rod speaker, cuz the tubes in the hot rod are finished ! And I miked it!


    The Kemper Is sitting here beside me , not working and there's nothing I can do about it.


    You cant know how frustrating it is !


    theres an old cleaning lady here and I was told not to touch her cuz she is bad luck, he calls her Evil Penguin! I didn't believe this superstitious non sense but I actually touched one of her boobs by accident and there ya go ! Bad luck !

    Bare in-mind that I've been using one of these (which I infact have 3 of them for my gear) http://www.lindy.co.uk/cables-…itioner-power-strip-p8835 within a couple weeks of me getting my kemper back in early February 2013.


    Unfortunately, the bugs were all to do with kemper firmware. Noise issues early on were mostly also firmware related. Too many bugs to list, but, most have been resolved now.

  • Finally just sent out my Kemper this morning , hopefully will be getting it back in a couple weeks!


    it's been hell playing without it, I will tell you guys.. When I finish this tour, which has been extended, I will think about buying a second one for sure as a back up because I love the machine honestly. And would probably if there was a dealer here!


    you don't know how much you miss it until it's not there!
    I haven't had it for five or six weeks and it's been just crappy to say The least guitar wise!
