I've got a GK 400RB, and want to know if i should buy a 8ohm cab and run it at 125w, or buy a 4ohm cab and run it at the full 200?

The 8ohm cab is $150, the 4ohm is $260.

Please help.

I'm pretty sure you need two 4ohm cabs or one 8ohm. Or the other way around, I forget.

If you get the 8ohm, you're gonna wish you got the 4.

Is there such a thing as a heavy riff with out chugging on the e string?

Buy the 8 ohm and if it's got multiple speakers wire it so that it's 4 ohm.

According to my past multitude of bass players (my old band went through them like groupies)

when it comes to bass... more wattage is better!

both are 210's

And it is the other way around, Sid. 2 8ohms make 4.

2 x 4 ohm cabs = 2 ohms will the amp run at that low ohms?!

a 4 ohm head will run 1x 8 ohm cab, 1x4 ohm cab, or 2x8 ohm cab

If you get a 4 ohm cab you won't be able to add another later.
Two 8 ohm cabs will sound louder than one 4 ohm cab.
Although the output from the amp will be the same (200 watts); runnig two cabs will sound louder due to the greater volume of sound.

Why is the 4 ohm so much more? Does it use different speakers?


maybe it puts out more?

I'd be playing small jazz gigs, no PA, and with sax, trumpet, drums and guitar.

Is the 125 watts in the GK 400RB a loud 200w?

Also, is it possible to change an 8ohm cab to a 4ohm cab? Is it easy? Should a pro do it?

you could rewire it if you knew what you were doing, it doesnt seem that hard as long as you research first, theres a tutorial on how to rewire cabs in the customization thread

A two 8 ohm cab set up will sound louder. "x10 and 1x15 would be good. 200 watts will get you buy but i would of msaid to get the 700 rb in the first place.

In most cases the final output in decibels (Dbs) is down to the efficiency of the speakers themselves, a combo with a speaker that has an overall sensitivity of 100 Dbs will sound considerably louder than a speaker with a sensitivity of 96 Dbs, so at the end of the day it is not all down to watts but a combination of the two :- amp output and speaker efficiency.

I'll be getting the 8ohm cab, and saving for another.

Should i get a 115 or a 210 to add to the 210 i've got now.

8ohms is twice the resistance of the 4ohms. Im pretty sure that amp can run 1 4ohm cab or 2 8ohm cabs. 2 8ohm cabs will have more projection, so it will be louder but it will be running on a lower amps, if its 300, itll be like 120 per side. 1 4ohm cab will be louder than one of the 8ohm cabs but will not have the projection of two of them. I would say buy the 4ohm cab and save your money.
