Problem with Genz Benz GBE1200

Try a little contact cleaner. It works wonders

 

It could also be oxidation in one (or more) of your jacks. Check out this article for more info: http://www.prestonelectronics.com/audio2/intermittents.htm

 

I am sure aged horse will check in at some point

 

did you buy new?..doesn't matter much ..we'll stand behind it..just want to know origin of amp.

Either way- NAMM week next week....so FIRST thing on Monday, call the shop: 480.941.0705 and ask for Jeff or Scott....tell them your problem. It sounds like we need to get the amp back.

Do you have a gig coming up for which you'll be challenged without your amp?

 

^^^ And that right there is a primary reason why GB is so awesome!

You simply will NOT see this kind of CS support from any other amp manufacturer.

 

Maybe try this . I hope it will help...On the back of the amp try working a jack in and out of the EFFECTS SEND and RETURNS on both FET and TUBE and MASTER LOOP .sometimes oxidation builds up on the contacts.. If you get some Tuner or Electrical Contact cleaner, spray it in the jack slightly and insert the jack a dozen or so times... if that gets relief from the issue you may just need a good contact cleaning... Repeat if necessary.. I had a similar thing happen to an Alembic Preamp and my old svt3 years ago

 

By any chance are you coming from a very cold environment into a warm humid environment? This is probably one of the biggest causes of intermittent contacts and connections on all amps (not just ours). Generally, a cleaning by the service dept. takes care of all of this, but give Scott a call at the shop and he'll take care of you.

 

I don't own a Genz Benz amp (yet), but after seeing the kind of care they have for their customers, I don't understand why I didn't get one already. When my SVT broke down the first time, Ampeg pretty much told me to shove it and made me pay for repairs (even though it was covered under warranty, but that's another issue). A GBE 1200 will definitely be my next head.

 

You will NOT regret it... I went from the GBE-1200 to the Shuttle 6.0, mostly because the 1200 was REALLY over kill for playing in small churches, which is pretty much the only time I take my rig. Most of the time I play at large churches where they expect me to go through the house and, if there is a rig for a bass monitor, use theirs. (The other reason is that my laziness quotient keeps going up as I get older!).

I'll probably be getting one of the Shuttle 12.0's soon - I just love being able to switch from the tube to FET preamp and blend them.

When the amp is cold and you bring it into a venue, often there will be some small amounts of condensation that when it dries can leave the dust and stuff that's settled out of the air onto the jack's normalling switch's contact surface. This is a pretty big problem with mixing consoles, but all manufacturers face this kind of thing from time to time. Usually it's the effects return jacks that are the likely ones. We have also found bits of spider web inside the jacks, spiders seem to like dark little holes in some parts of the country.

If the problem persists, try plugging and unplugging a cable into the effects return jack and if the problem disappears you are good to go. This applies to all manufacturer's products using serial effects loops.

 

Thats why I just sold the last of my Eden gear and switched to GB. I now own a GBE1200, a Shuttle 6, (2) NeoX 212 cabs, and a NeoX 112 cab. I'm covered for any venue and like having the peace of mind I can get help IF I ever have any problems with the gear.

 

you have the 1200 in some sorta case? I always keep the covers on my Gator/SKB cases closed tightly while they sit waiting for a gig. I take a small cloth now and then and wipe the inside of the cases and around the amps to get dust out of there.

I also have a can of compressed air I use on my PC.
Anyone know if spraying this into the amp(s) openings would keep it clean or is that overkill or just bad for the internals of the amp? Hope your 1200 issue stays away now and yeah we love that GB customer service. They've helped me a couple times over the phone and by PM or email, very cool.

 

Won't help, it's at the molecular level on the surface of the switch contacts. It's worse typically when they are unused for long periods of time. Again, this applies to every manufacturer that uses switches and jacks.

 

Wow,
So when I first saw this thread I thought, 'Holy Crap, what did I get myself into!' because I have a GBE due to arrive tuesday. I bought a used Ampeg this past March and it was still under warranty but I did not have original receipt. I paid to have it fixed when I burned up the first time. When I opened it up, it was obvious that it was not the first time it had happened. I called Ampeg and wrestled with their customer service people and they sent out another which also blew. Then another that blew, and now is getting repaired so I can sell it. I have burned up 4 SVT6 pro amps this year. 3 of them in front of a crowd of people. They say there is a moification that needs to be done to the amp. Luckily, I had a Mesa Pulse 600 plugged and ready this last time. I thought Ampegs customer service was good at first, but they will not fix another amp for me and now, I really cant trust them.
I am excited about my Genz Benz purchase and now feel better knowing these guys are out here in our world taking care of us and building a good reputation by standing behind their product.
THANK YOU!

Bill

 

As a long term Peavey guy, that is also why the GB amps are in the running when I add a biger amp in the next year, or two....don't get me wrong, there are a lot of amp companies that represent themselves well after the sale, but the guys at GB sure stand out!


Sorry for thehijack, we now return you to your regularly scheduled programming.........
