So amazing to see the actual owner and head of the company do a video like this. Bob Gallien is a true electrical genius and after all these years, his dedication to the sound is still evident. Ever since I discovered GK amps a few years ago, I'm GK for life. I have the 4x10 Legacy combo and I could not be happier. Perfect tone. More power than I'll ever need. Built like a tank. Bonus that it looks tough as hell. #GKallday
This head is amazing! After using it for two weeks and playing on stage with a reggae band and three different rock bands, this amp blew away all my expectations! The punch and GK tone are all there in a small, light and mighty package. Thank you Bob, Forrest, and all the crew at GK for developing a phenomenal product!
I can see Mr. Gallien is very proud of this product and he should be. Looks like a lot of thought is put into his products and they built a beauty here. Great explanation of how it works, straight from the horse's mouth! My 400RB is still happily cranking among. GK, best sounding bass heads out there!
Great video, thanks. After years of using various other brands I have bought a Legacy 115 combo which is a great piece of equipment. Very impressive indeed. This is a very informative and helpful video, thank you.
Very nice demo Bob and Forest. I have been playing bass since 1969. Picked up my first GK in the 80's, I don't remember the model. Later I bought an RB-400iii with a Backline 115 and Backline 410 cabs. I played that setup for probably 13 or 14 years. I'm 68 now and can't haul that much gear anymore. About 12 years ago I bought a used 115 Backline combo for band practice, it never failed me. Several years ago I bought a MB 115-II from Sweetwater which is plenty for gigs and I use the direct out to the PA and only 38 lbs it's easy to haul around. I would really like to get the Fusion 115 or Legacy 212 but being on a fixed retirement income now will be hard to come up with that kind of scratch. I have nothing but positive things to say about the four GK amps I've had over the years. Thank you so much for a superior product!
The Fusion version is the best amp I’ve ever owned in the class d style amps. The trim knob and voicings make balancing with and with out a pedal board easier.
I own an 800rb and i was curious as to whether the "boost" control is the overdrive in question because i have never pushed it enough to hear anything but clean from it without the addition of pedals, also you guys were fantastic at answering my questions about the 800rb when i called. Instant on hand info about a product from 30+ years ago, amazing!
Basically this overdrive allows you dial in everything from a boost/growl to full on heavy overdrive. We wanted to give people the ability to dial in that "hitting the rails" sound without having to crank your master/boost channel to get the amp to break up
@@Gallien-Krueger ah i see, so amp breakup on 800rb is safe to do? Ive been avoiding it out of fear😂 i have one of the original line so i treat it well
I appreciate how well you demonstrate how your products work. I just recently purchased a GK Fusion 210. Can you make a video on that? I feel like there is alot I can learn on it. Thanks!
This is a great overview! As a recent GK buyer of the Fusion S, something like this is very helpful. Any idea when the Fusion version of this will be out? I'm having a hard time figuring out all the controls, especially with the push button toggles. No one else seems to be able to explain it well.
I think my math should be correct if I've understood it all but could someone help & confirm? 😅 So would the following head + cab combo work well: GK legacy 800 (800w output at 2.7 ohms) with GK CX410 4 ohm cab (800watts) + GK CX 115 8 ohm cab (300watts). I think this would be awesome. So (8x4)/(8+4) = 2.666 ohms would be the total ohms in parallel, and with 4 ohm + 8 ohm cabs it would mean that 2/3 of the heads power goes to the 410, so 2/3x800=533 watts for that and 1/3x800=266 watts for the CX115. And which was the position the back nob should be turned to? (8 + 4) right? Thank you! I love your bass cabs and amps!
Best review out there I have a MB 500 and I don't know if I want to swith to 500legacy or 500 Fusion S can you make a 500 fusion s review like this? I know it takes time. Thank you for your products. all the way from Romania.
I have a question about the ohm load. I believe my amp (legacy 800 like the one in the video) has a different order for the switch on the back. Mine (from bottom to the top) is (4+4) - 4 or 8 - (8+4). Is this an older setup or am I running my amp wrong?
I agree that he mentioned the middle and top positions in the wrong order. I have two 8 ohm cabs that have their own parallel connections to join them together making the total load 4 ohms and I would like to know if I need to use BOTH output jacks on the back of the amp or just one? The rear outputs are in parallel as well so running a cable to each 8 ohm speaker from each output still renders 4 ohms. My total load is 4 ohms in either scenario and I believe I need to set the switch in the mid position which, if I understand correctly, is for either a 4 ohm load OR an 8 ohm load. A 4 ohm load = 800 watts output and an 8 ohm load = 400 watts output with the switch in the MID position. I would also like to see the switch recessed into a small cavity so it’s under flush with the back surface or a clear cover of some sorts to protect it from being moved accidentally when handling the amp. I’ll be using a small piece of tape on mine.
Thanks for the info. I did end up getting rack ears to store with my shure wireless and in ear receivers. May be a solution to the switch thing you mentioned.
I didn't follow all that well the cabinet impedance explanation. I'm currently running 4x10 4ohm cabinet, what position should the switch be in? He says " middle position is 4 + 8" and mine says "4 or 8" and that's where it got confusing.
i dont understand the impedance? i have a Hartke HD112 cab with a 4 or 8 ohm switch and a Legacy 500 with a 3 way impedance switch what do i set both the cab and head for optimal performance?
Just leave the switch in the middle on the Legacy (4 or 8) and you can choose either 4 or 8 ohms on the cabinet. 4 ohms will draw more power from the head, so 8 ohms for the single 112 would be the best fit!
The Contour boosts the highs and lows while reducing the mids. It creates a more "scooped" sound that a lot of slap and pick players love. We label the contour as a "Voicing Filter" as it changes the voicing of the amp, while still allowing you to adjust the standard 4-band EQ to your liking
Music stores seem show the fender rumble 800 head as the knock off version of this at half the price… they have all the same controls… but i imagine the EQ circuit is totally different?
@@Gallien-Krueger Thanks so much for the reply. I read Flea uses some of your gear is how I discovered you, … at first I was going to go the tube amp route, but for bass guitar, even the tube amps these days have so many solid state components, i really question if i need a couple tubes in there at all… those solid state amp heads you have sound perfect as they are to me.

Probably the best amp demo I've ever seen. Great work. Making me want to go back to GK after many years away.

And this is why we do it! Love to hear that you're happy with the Legacy, thanks for sharing!
which do you have? 500, 800?
The best amp company ever! I've had experience with many GK products in the past and they all sounded stellar! Always built as a tank!
Happy to hear it, thanks!

that trim control is a great idea
Great stuff, nice to hear all that manufacturing stuff. The eq really sounds nice. And a usable overdrive too.
this is a excellent demo! given by the guy who designs it!
Very helpful and very timely for me, I just bought a Legacy 1200 and am trying to better understand the amp. Thanks very much!
how is it now?
The Fusion version is the best amp I’ve ever owned in the class d style amps. The trim knob and voicings make balancing with and with out a pedal board easier.
Sounds way better than my Aguilar tone hammer 700
Might be time to make a change!
Thanks for sharing wow nice demonstration 🎸🎶🎵🇬🇧
Sounds like someone running there fingernails down a chalkboard. Exactly what I’ve been looking for

Just released the Fusion overview video, it will cover everything you need for the combo! Check it out on our channel!
Go will be my next amp like that most of your process of building is all in the us good stuff
Awesome
Great demo.
Sounds great!
Thanks for the tips
Thanks for watching!
And that's how You do it!
I have to try one w/ my Stingray so bad! :)
You'll love it. I get such a nice bite and grind out of my Ray 4 through my Legacy and MB Fusion
I absolutely LOVE my 700RB, but (now that I'm older) it's a bit too big and heavy. This looks like the perfect solution.
Definitely!
Thanks! Just ordered mine today!!
@@revazquez Awesome, hope you love it!

I waiting for MY GK Legacy 800, one of the last in EU ;)
How'd you go?
I think my math should be correct if I've understood it all but could someone help & confirm? 😅
So would the following head + cab combo work well:
GK legacy 800 (800w output at 2.7 ohms) with GK CX410 4 ohm cab (800watts) + GK CX 115 8 ohm cab (300watts). I think this would be awesome.

And which was the position the back nob should be turned to? (8 + 4) right?
Thank you! I love your bass cabs and amps!
Nailed the math! This is a great combo and you are correct, switch to the 8+4 setting and you are good to go!
@@Gallien-Krueger Thank you so much! 🙏
Pretty sure I saw the guy on the right on Raising Hope.

Coming soon!
@@Gallien-Krueger Thank you very much! I am really interested to buy the new one, still love the mb 500 sounds amazing.
Can you guys please do a comparison between this and the old 80s or 90s RB series heads.

Is it fusion next? I’ll wait.
yup!
My Legacy says 4 or 8 on the middle switch selection, not the top. Is this an error on the video?
Mine as well. Wondering the same as you.
I have the same question.
GK, are you saying that switchcraft input jacks are made out of TIN? or what type of jacks are you referring to that uses TIN
I think he’s referring to their solder connections, not with the material of the overall jacks are made of…
I didn't follow all that well the cabinet impedance explanation. I'm currently running 4x10 4ohm cabinet, what position should the switch be in? He says " middle position is 4 + 8" and mine says "4 or 8" and that's where it got confusing.
Pretty straightforward… 4 and 8 and the other one is. 4 or 8….
i dont understand the impedance? i have a Hartke HD112 cab with a 4 or 8 ohm switch and a Legacy 500 with a 3 way impedance switch what do i set both the cab and head for optimal performance?

Is contour just an eq? Cause it sounds like it's also compressing the lows

Still putting out updated RBs this year?
Music stores seem show the fender rumble 800 head as the knock off version of this at half the price… they have all the same controls… but i imagine the EQ circuit is totally different?
Couldn't be more different! No one builds an EQ section like us, it might look the same but we use many more parts and have variable eq
@@Gallien-Krueger Thanks so much for the reply.

Do you make any models all tube? For bass
I don,t see bi amp on this and I like bi amp. No burned up rheostats.
What does"dimed" mean?
Turned all the way up!
who is the substitute of RB Series now???
You are looking at it.
Beautiful amps and great explanation of what it does but hard to watch with that klanky sloppy playing next time get a better player
.
This amp sucks! I'm going back to Eden!
Should’ve stayed at Eden , nobody wanted you over here
Did he have to use the worlds most horrible bass player?!
They're demoing the amp, not demoing skills. Good lord.
@@theghosty99 EXACTLY Shortbus, they're demoing the amp and need someone to make it do what it do!
