For most amps, yes. But I've run my 1001rbii the opposite as well. Just depends on the sound you prefer.

RB amps hit the rails and yield a unique distortion when the power amp is pushed to the upper end of its supply voltage. These amps have the master volume labeled "woofer."
From the 800RB which was a bi-amp, hence woofer and "hi" end amp.
Started with the 800RB. The 700 and 1001RB's are also biamped with a 50-watt amp connected to the horn tweeter in the Neo cabs through a 4-wire Speakon cable. The master volume controls are labeled "woofer" and "tweeter."
Yes.
I grew up with RBs in the 80s and the MBIIs definitely get there.
Do you have an MB112-II? Can you make it growl or hit the Rails without using the Plex?
Ohhhhh...I don't see a way to drive it in the way I'm used to then. Sorry for the bad info.
Growl is one thing. But the actual rails thing is the RB class H power amp being pushed to the upper end of its supply voltage. Not sure that happens with class D.
This is what I wanted to ask, got pulled away. How would you push a power structure in this way without Gain & Master Vol to go between... and for gigs not involving lots of stage volume I'd probably want something like a 400, maybe an 800RB, but a 1001RB would be out of the question. Amirite?
My experience is with the 700RBii and 1001RBii. The 700 hits the rails easier (at lower volume) than the 1001. It would make sense that the 400 would do so more easily than the 700.
For me, the rails thing happens with pushing the power amp to its maximum — high master, hi boost.

You most certainly want the 400RB based after your description.
That is the amp you that gets the rail sound the easiest IMHO.
I would figure, yes. We're a rock band, but we're a pub/club band, so smallish rooms. FOH for bigger rooms.
It's probably already been asked a dozen times but does anyone know how to decipher a GK serial number? Would love to determine the manufacturing date [or at least era] of my 1001rbii, if possible.
Thanks in advance!
Thanks in advance!
After taking in my gk fusion 500 twice to where I bought it for up for Repairs….
I have to take it back a third time for the same intermittent issue as before
looks like the tech was fed up and decided to send it to Yorkville sound

Just got it back from the tech. He said it needed a thorough going through. I only had a minute to play it before work but it does seem to be working properly again, so huzzah!
Nothing but pure thunder [per usual] from the 1001rbii at yesterdays vintage motorcycle show.
I pulled out my old MB150s from 1991. I reconed the speaker with a kit from Speakers express because the foam surround had disintegrated.
I also recently got a small amp stand - I think I got a Gator.
Holy smokes this thing sounds incredible. I've been using a Roland Micro bass cube for practice, and it's a great piece of equipment for its intended use, but the tone of the GK is just in another league.
With a PJ and EB Colbalt flats, the tone is warm and mid heavy and with a 5 string super J with rounds, it's crisp and bright.
The GK used to be my only amp. I used to for practice rehearsals, and for gigs I ran it through a Hartke 4x10 and used the direct out to the PA.
I know it's not a really fair comparison, but it's much more inspiring to me to have a killer tone when I'm practicing.
I need to figure out if I can use the effects return of the MB150s for play along tracks.
