GALLIEN KRUEGER 800RB

[Konan888]

I need help. I jus bought my first setup ever. One Canadian made Traynor 1x15. One Ampeg 2x10 SVT210HE American made. One GK 800RB head. One Fender bass. I love Reggae. My Ampeg 210 was screwed. Service center said it was the safety circuit. Went home. Set it up and it is still screwed. I checked the head and confirmed it is not the head. I now want to dump the 210 and am considering buying a Traynor 210 to match the 1x15. I need to know what you think. Fix the ampeg or screw it an go Traynor. I would also like to know if the GK800RB is enough to drive them. It is a biamp x100, x200 or x300 total at 4ohm.

Cheers and thanks!

I have an 800RB , love it. What are the OHMS of both your cabs you are trying to push through it?

I play 2 8ohm 4x10 GK cabs through the 300 watt section, sounds great.


btw how much to fix the ampeg? how much for the traynor?

[Konan888]

The Traynor 1x15 is 8ohm and rated at 450w. The Ampeg 2x10 is 8ohm rated at 250W
So far $60.00 and I am considering taking it back in tomorrow. The new Traynor 2x10 is $470.00.

Okay..its late..maybe captain obvious just popped in for a drink.
BUT..shouldn't you have asked this question Before getting the 800?...Im just sayin is all.


And yea, BTW, you should be okay with that.

[Konan888]

I agree. I did ask all of the right questions. I was dealing with Long & MacQuade which is a music store in Canada. They said it would be a good set up. Now I do not know.

What do you think about the Ampeg question? Try to fix it again or dump it?

[A-Step-Towards]

Ok If the ampeg can be fixed for 60$ and you like its sound then I would fix it for the price thats not bad, however I would want some guarantee on the work.

You can run both those 8ohm cabs through the 300watt 4ohm side and it should work fine. Also make sure to use speaker cables not guitar cables.

[Konan888]

$60.00 was for the previous work.

Thanks A step.

Cheers!!

the GK800RB is one of the best SS amps ever. it will make an ampeg svt cab walk and talk for ever. plus you can bi-amp with it.

[Konan888]

Awesome. Thanks! Do you think it is best to plug the 2x10 into the 100w high and the 1x15 into the low 200w? Or would it be better to run them both from the low at 4ohm 300w?

You cannot do this (bolded for importance). You can run one 8ohm cab into the 100w high because its rated at 8 ohms, the 300 watt section is rated at 4ohms though so you have to run either one 4 ohm cab into it or both your 8ohm cabs.

Please do not run one of your 8ohm cabs into the 300watt 4ohm minimum side, that will not go over well. You can if you wish just run one cab through the 8ohm 100 watt side for smaller gigs and for bigger ones run both your 8ohms into the 4ohm 300 watt section.

Actually he should be fine running an 8 ohm cab on the 4 ohm side. I do it at my house all of the time. It is not an issue with SS amps, you just lose a little wattage, but it will still be pretty loud. You would not want to run a 2 ohm load on the 4 ohm side.

WRONG....(bolded for importance)
It's perfectly fine to run one 8 Ohm cab out of the "Lo" side. The amp will deliver 200w. With two 8 Ohm cabs it will deliver 300w. There is only danger if you run below the rated impedance. (8 Ohms "Hi"...4 Ohms "Lo".)
(BTW..do not run below 8 Ohms out of the "Hi" side)

That said, I'd run both cabs full-range out of the "Lo" side, unless the sensitivity of the two cabs was so different that you would need to control them with different volume levels.

And don't worry about power unless you need extreme levels. I've used an 800RB many times in arena or outdoor festivals. G-K rates all their amps very conservatively.

why this thread titles "Gallien Krueger 800RB"?!?!?

Why? I have done that a lot of times with that head. He wouldn't want to go too low like a 2 ohm load, but he can go up to a 8 ohm load, he just wont get the same amount of power, but it won't hurt the head or the speakers

[Konan888]

Thanks again. Appreciate it.

[DrewinHouston]

I run an 8-ohm cabinet out of my 800RB low output section all the time. You can do it just fine. It won't hurt the amp or the speaker cabinet. It's designed to handle 4-ohm or 8-ohm loads out both sections. It just won't produce the 300 watts rated at 4 ohms. If you don't believe me, take a look at the 800RB Operating Manual where it has a power rating for 8-ohm loads.

I agree it's important to note that you shouldn't run lower impedence loads than rated (like two 8-ohm speakers in the high section).

Try both ways. That's part of the fun. If each of those cabs are 8 ohms, it would be a perfect 4 ohm load for the 300 watt amp.

Get 2 more tens and throw 'em on top.

I've run some fun combinations in the past.

8 10's + 2 10's

2 15's and 2 10's

This is correct.

[bassman5959]

Tube amps only require exact ohm balance. solid state is much more lenient.

If you want a cool reggae sound with the 800, get a 2x15/4-ohm box and a 4-10/8-ohm box, biamp, set the crossover hard right, and crank the low section with half power on the highs. Ka-thump!!!

[skulletwhip]

I just scored an 800RB for 200 bucks. I love it.
