    i bought a brand new gk 400 rb 3 from sam ash to take to bermuda with me as i am teaching bass and gigging here. it is a dream gig by the way .It was a light portable rig where it would be cheap to bring it over here on the plane and i could get my money back and sell the rig when i left as i have 2 swr rigs at home in the states .I also bought a ampeg portabass12 cabinet and a brand new skb case for the head it sounded killer and would be easy to tote around .Well after about three hours of playing time the amp started cutting out the input would die nothing from the bass but the amp was still on it was like a speaker protection the the amp would work again after about 5 minutes and die again then it totally died I called gk and they said they could not figure it out and to send it in on warrenty and that sam ash had sold me a floor model as new I called the store and they said too bad it was past 30 days I will take care of that when i return. Now GK will repair the head i have to pay shipping one way and they will pay it back U.P.S. ground but I have to make up the difference to bermuda The cost to ship both ways for me is 240.00 and will take at least 2 weeks both ways .I am upset_ I bought the amp brand new and now i am out 100.00 duty, the 450.0 I paid for it and I have to rent a head for gigs, as I am only here for 3 months it is not worth sending it in i will have to wait until i get back.And sam ash where i do a lot of business is no help at all, i got ripped off. By the way there are a lot of great players over here ,they all hate G.K. so that is my sad tale. If anyone can come up with some ideas on what the problem might be i would be forever grateful. I should have bought a swr workingmans 12 , but i had a old 400rb and it lasted me for 10 years The thing that really gets me mad is the fact that the salesman at sam ash knew i was coming over here and sold me a floor model as new.But the ampeg cabinet sounds great. Any advice on the head will be appreciated :crying:

    Just curious...does the green power led turn red when this happens or does it stay green? It'll turn red in protect mode, so if it doesn't you might look at possible connection problems. If it's red, there was a defective design at one point in that series that was recalled. I tried two combos with that head. Both had the problem and went back and I bought another brand of amp. I think GK was a low point in customer service then, but they've improved in the past year or so.

    actually the light stays green at all times once it comes on the red light is only on when I first turn the amp on .Maybe it is a connecton problem GK is in total denial they say that model has no problems.And there are no GK service centers here but if it is somrthing simple the tech here could fix it thanks for your feedback i am finding out nobody has much luck with the newer models .

    You should be able to find something about the III series problem, but if your amp's power light doesn't turn red, it hasn't gone into protect mode. Good luck!

    I've never had problems with my GK 400RB-III in a year and a half. I think your problem may come from a change in voltage.

    Take it to a local tech. Have he or she check the pre-amp board for poor solder connections. This was the case with my 700RB/112 combo (which is the same vintage and same pre-amp board as your 400RB III). The fact that your LED doesn't go red is a good thing, I think. It may be simple for a local electronics shop to troubleshoot.

    Best of luck.
     
  10. The only problem the 400RB-III had was an issue with the fan. Check to see if your fan is coming on. It may be overheating. call back in to the office. I'm sure we can help you resolve this somehow.

    thanks for your coments the voltage is the same as the states . and the fan is coming on when it starts up and shuts down but it only comes on for a second but the tech at gk said that was a sign the fan was working . I am more angry at sam ash then gk, if it was not the shipping costs and duty issue i could ship it back if i was in the states and they would fix it. but i am here for 3 monthd which the salesman at sam ash knew and sold me a floor model as new which i would have never bought from that store. so i got shafted. anyway keep the tips coming in i am checking out all suggestions and i will call gk again

    I have no experience with G&K so have no direct suggestions, but I do want to say that any amp can develop problems, and I wouldn't hold it against G&K. It's very difficult to fix an amp remotely. If it were an operational problem they might be able to help, but I often find that what the customer says the problem is has no relation to what's really wrong. G&K is honoring what they promised. You might be upset with Sam Ash, but again why would a floor model be any more likely to develop a problem than a fresh out of the box one? The floor model didn't "burn up" by being used. It in fact was "proven" to work through extended use. I don't like the 30 days too bad attitude though. Being in the middle of the Atlantic brings special circumstances to the problem, but short of flying a tech to Bermuda, what can be done?

    I would suggest the same as above. Have the amp serviced locally. It's probably not a big problem, and is most likely a loose connection. Maybe even a loose wire on a connector. No manufacturer stays in business building junk. I'm pretty impressed with the tone of G&K. I've never seen inside one though. You might try to get G&K to reimburse you for the repair once you get home. You'll probably feel better after 3 months in the sun.

    You might also consider it the cost of doing business. In Barbados the laid back expression is, "These things happen!" :cool:

    Sweet deal.
    I had a problem with a Gk 1001rb I purchased 7 months ago. Gk worked with the shop I took it too and coverd the repair costs even though I purchased the 3 year old amp used.
    I've been playing on it at least 3 hours day for 6 months since. GK or the highway.


    **edit**
    also I bought the head broken from Guitar Center and they didn't offer me any help and suggested the worst shop in town to fix it at my expense. When I purchased the head I suspected something was wrong with it but was reassured by the "bass expert" who told me the low volume was do to all the ambience at GC. He also told me I could bring it back in if it didn't work.
    go to guitar center for 1 reason and 1 reason only. If what you want to buy is hard to find locally and too heavy to ship.

    i took my head to Ornamental Electrinics here in Bermuda the guys name is Allen Decouto he is the best on the island and he fixed my amp It was a factory defect bad soldier joints and connections on the input circuit board ,It works great now it costs 150.00 to repair it which is a monster deal here in Bermuda. Alan is a expert on all kinds of gear i got lucky here a lot of people here hate G.K. heads for some reason but now they have a place to take them to get fixed .One guy has a 400rb head that still works after 15 years , So hopefuuly it is cool but the reason that I got some response from Sam Ash and G.K. was this Talkbass Forum . They both offered to make it right once they realized it was on Talkbass . And G.K. is paying for the repair I am glad as i always like their gear it is good to know there is product support after you leave the strore thanx StRANGER IN A sTRANGE lAND i WILL GET ON ANOTHER FORUM AND TELL THE EXPERIENCE OF TEACHING BASS OVER HERE AND GIGGING HERE cTRAZY
