GK 400b or 400 rb

OK...I'm pretty much ignorant in the Amp area so help me out. I did search a little but didn't find what I wanted so...
Which would you choose and why? Thanks for the input.

Not sure what the 400b is, but GK's 400rb amps are a classic, and great amps. But, speaker cabs are even more important, so anything you get will depend on those.

Yeah.... never heard of a GK 400b..... the 400RB is a very nice sounding amp and is reliable as they come....

the 400B was an old GK amp from the 70s:

I have a late 80s 400RB and it's a terrific amp, use it for my DB as well as rehearsal rig.

I don’t know anything about the GK 400B except it was introduced in 1975.

I had the 400B for 18 years, then lent it to a GUITAR PLAYER (friend of mine) who gigged with it for 10 years, then sold it to another Bassplayer, who had a choice between it and a SWR head and picked the 400B because it still kicked ass.

Great amp. Wish I kept it. By the way, the guitar player’s tone through the 400B was amazing. He had pedals and ran it into a 4x12 guitar cab and it held its own against a Mesa Boogie full stack.
