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!
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 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!
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.
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 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.
