Gallien Krueger Introducing NEW RB Legacy

Yeah, and what's all this about "rails" and "riding the rail"?

Are they marketing these toward hobos?

“I preordered mine!”

…but you don't have Sisma any more…

Is the GK heavier sounding?
No, it would have been nice to get a Sisma. That's the tester that was floating around TB. I sent it on to Sean Hurley. Don't know what happened after that. I know he used it on some gigs. Might have to see what happened to it. (Note to self, bug Hurley :))

The GK sounds different. It is heavier in weight. Those were the ones I wasn't too lazy to get to use to compare the Sisma with. Maybe because I used that same cabinet, but the three sounded like they were in the same ballpark. All flat, the Sisma sounded the thickest, then the GK, then the WD. I thought the WD had the most tone variation possibilities, the GK and Sisma seemed to be neck and neck in that department. I thought the drive qualities were closer and more desirable in the Sisma and WD than the GK which was fine but the other two seemed more organic, perhaps because of their tube front ends.

I wonder what the burst power of the 700rb II and the 1001rb II is?
The 700 and 1001RB exceeded expectations by a lot don't they?

I was using a rack preamps with a QSC PLX 2402 before I got my 700RB-II.
I was initially skeptical, but that scrappy "little" 480-watt power section sure didn't lack for volume!
 
Same with the 400RB. Here on TB amps under 300 watts are viewed as substandard by many. Mine ran with a hard hitting drummer ran through a Sunn 215. I heard them rip through SVT 810 cabs as well to great effect (though probably less often than 800RBs were back then).
I felt the 400RB just had a great focus, especially compared to older gen SS heads like Peavey MkIVs, Acoustic, or worse like Kustom etc. Those often would sound good at first then heat up and kinda go fuzzy and limp. To me that is whythey became legendary.
 
Surprise surprise!

Is it just me or do the words "New" and "Legacy" seem like an odd pairing? "Legacy" by definition refers "older" or "previously excellent". Just struck me as funny to see the phrase, "Introducing New RB Legacy". It's a bit of an oxymoron. ;)

Hey, you're right!

In a similar vein, I saw this at the Burger King drive-thru, a Ford Expedition Max Limited:

How can it be "MAX" and "LIMITED" at the same time????

If it's "limited," then the actual "max" is MORE than they are giving you, since they just limited it!

Hmmm???
 
Just for reference, my QSC GX7, which I use with my Demeter and Alembic preamps, is Class H, 1000W/4 ohm ch / 1200W into a single 4 ohm cab. That is a mainstream power section and works extremely well; only “problem” being that care needs to be taken with all that power. 21.5 pounds.

So, that power section choice for a high power NON Class D power stage seems to me a good one.

That reminds me.

One of the last great things the old Carvin made was the DCM-3800L power amp.

It has a switch mode power supply, Class AB, aluminum chassis, 2 rack spaces, 10.5" deep, and weighs only 14lbs...and puts out an astonishing 3800 watts RMS at 4 ohms bridged at less than 0.1% THD.

I scored one when they closed their doors for $300 brand new.

Now, I have enough power for quite literally anything; any cab, any possible scenario.

Even the Class D 'bois can't scoff at 14lbs...well, I guess they still would.

I have one. That is one of the last Carvin things I have that still works. Other then the BX 1500 with its ribbon cable issues and some DI and phantom power boxes. 😊

As someone who put a lot of hours in GK amps supplied as backlines, but always felt like I could never afford to buy one, or have the physical strength to carry a heavier rig with toroidal transformers around town, I'm glad GK also has a line of light-weight Class-D amps.
Like all things GK, these probably sounds fantastic.
