A GK 2001RB and a Fender Bassman?

So i'll be getting a GK 2001RB amp head soon. But i'm wondering how it would sound with a 700W fender bassman 4x10. I have a Rickenbacker so the treble will be pumpin! :cool:


But since the GK2001 is a 1080w amp and the bassman is 700w, i just can't raise the volume too high right?

edit:
Oh and the Fender bassman is 8ohms... crap i didn't know that! :/

I guess I misunderstood. I thought you were disappointed the cab was 8ohms and therefore wouldn't wring out all the potential power of the head.
I personally like 8ohm cabs because I can add one if needed for large venues. A 4ohm cab is beneficial if your amp is low powered at 8ohms but that certainly isn't the case with the GK head!
 
At 8ohms the max the 2001rb can do is about 500w, with both amps bridged. If you look on the back of a 2001rb ( [Invalid or Expired Link Removed] ) it has a chart that shows woofer loads. If you run a second 8ohm cab or a single 4ohm then you could possibly hit the 1000w mark, but you won't get all that much power out of the head if you only run a single 8ohm.

Also, the Fender Bassman 410 is 700w "program", or peak, and only 350w "continuous", or RMS. This means that really the cab is a real-time, useable 350w, not 700w.

So when you run your Bassman 410 through the 2001rb you'll get 500w if the amp is in bridge mode, or just 200w if you run it normal, but the cab is only rated 350w, so you could run the amp bridged for the 500w and keep the volume low so as not to overpower the cab. Or two Bassman 410s would give you the output of 1000w, but the cabs handling maxes out at 700w.
 
The GK 2001 has a LOT of power. The Fender cabinet will be fine if you don't crank up the bass at loud volumes. There are better 4x10 cabinets for sure but if you use common sense you should be fine. Even at 8 ohms the amp can drive the speaker into really unpleasant distortion, but it should be annoyingly loud before then.
 
If i ever wanted to bridge two 8ohm speakers, their RMS should be 540W if i want all of the GK power right? I'm just making sure :)


edit:

my friend is selling me this bassman cab for 400$, is there a better option? ;o
 
it goes like this;
if an amp puts out 1000w in to a 4 ohm speaker system, then it will not put out
as much power in to an 8 ohm (higher resistance) speaker system.
also theoretically it should put more than 1000w in to a 2 ohm speaker system
(not all amps can go down to 2 ohms without damage)
i think GK rates this head at approx 500w when bridged in to an 8 ohm speaker
system
 
the GK puts out 650RMS bridged into 8 ohms - i think you will easily destroy that cab if you aren't cafeful. i run mine into my SWR 12-stack which is an 800 watt, 8 ohm cab, and it drives the hell out of it - the GK is massively powerful so regardless of your cab's power ratings, be careful with cone over-excursion. this is one amp where i think you really need to be careful with the power - it needs a high power, high quality cab to get the most out of it, and also to widthstand what it is capable of putting out.
