    I've been playing for a lot of years and because I'm older and smarter now I looked for a system that was straight forward with plenty of power and most of all these days portable. I found all of that with Gallien-Krueger. I use this head with a GK 410 4ohm NEO cabinet bi amped to get every bit of that power. This setup handles the low B of my Fender's and Lakland's with ease. (The 410 NEO is a powerful lightweight cabinet which I can actually lift and put in the trunk of my car all by myself without singing soprano.)I have never had a situation where I have ever felt as though I didn't have enough head room or that I couldn't hear myself on stage with this head. The sound guys all agree it has a great sound that is easy to work with and easily comes through in the mix. I always get compliments on my sound on every job especially from other players. I started out years ago with the GK 800RB and it served me well and most of all dependably for many years. As I got older and was able to afford boutique amps I did and I strayed away from GK spending big bucks looking for a better sound and never found it. Nobody gives more bang for the buck than GK does and none of those expensive amps were as well defined live with the sound such as this amp produces and most were not nearly as straight forward to use. This head is just straight forward clear defined bass tone with easy to use controls and no messing around. Just jack in and play. Enough said!

    The GK1001 is a really good head with plenty of power and headroom. I was surprised it had that much of both with the GEO@8OHm cab. I usually play all tube Ampegs, but I really like this for clean audiohile headroom, especially for articulation and slap. Do yourself a favor and buy the 4-way cable directly from GK so you can bi-amp the head.You will be surprised how the amp comes to life.

    I would have given it 4 stars instead of 3, but after all it is GK! Terrible quality problems with the 700 and 800RB. Few problems reported w/ the 1001 but I am distrusting enough to buy the Musician's Friend 3 year warranty. Like I said, it's not the 90's and this is GK

      Comments about Gallien-Krueger 1001RB-II 700/50W Biamp Bass Head:

      I've played through many heads of all major labels over the last 40 years and I can say without a doubt, this is the BEST! I'm running it through a GK 4x10 and GK 2x12 cabs. It will make your ears bleed before you ever get it to clip. In fact, I have yet to use up all the head room. The first head I've ever had that I can say that. I doubt you'll ever have all the bass settings much past halfway and the tone control with the Bi-Amp is simply amazing. All the tight bottom, quality mids and smooth highs you can possibly want without ever coming close to max settings. I started out looking for ultra light amps to replace my old 30 pounder, but heard too many horror stories of them not having the powerful head room they advertize. Most of them only had one speaker out too and not all cabs are in/out. If you can't pick up a 23 pounder instead of a 13 pounder, you probably can't pick up your guitar. I can't say enough. Get you one!

        I use this in combinations with GK 4x10 Neo and 1x15 Neo. I love it! so many different sound possibilities!Main reason for purchase was the biamping feature. I'm blown away and so is anyone else near the amp!

            I just got the amp, so I can't speak to reliability, but it's one of the best sounding amps I've played. It fills up all the notes. And I haven't even tried the biamping yet.

                  I use this in a studio where I do overdubs. It's not moved so can't talk about that. I get a wide range of tones and sounds with it just as it is. The lows are crisp enough I run the EQ flat. I run the DI as post-EQ and have never had to switch to a direct box. Easy to use. BTW the negative review here is about speakers - not this unit. It should be posted in another location. Thanks.

                    The Gallien Krueger 1001RB is nothing short of spectacular. The functionality of this amp is a plus compared to other heads on the market, but the sound, volume, and tone of this head is making a new name for Solid-State. I even started to call it "Beast-Mode". If you are a Bass player and think that tube is the way to go, think again, this head blows away most tube heads and you will NEVER have to worry about Volume with this head. You want another fun fact? The Bass Rig the backing musicians on "The Voice" use is this exact Bass head. Its that good, its professional, its versatile, and it don't dissapoint, buy it!

                    I was very pleased with this purchase. I was looking for a powerful, bi-amp capable head with great tone and neccessary features. I found it in this unit. Very pleased with the sound I am able to get from this amp, along with the tone controls, bi-amp switching and controls (used with a GK cabinet, of course). It gives me the control I need over the sound without extra, useless features to add cost. I find this to be a much greater value-for-money deal than the Ampeg SVT-3, which I have used extensively. Good amp but overpriced. Not so in this case. You get what you pay for and then some. I personally prefer the sound, too. I do wish it came with a headphone jack, though, but that is no deal-breaker. This is a stage amp anyway, and there are ways to get around that thanks to the direct out feature. Overall, very pleased with this equipment.

                    Comments about Gallien-Krueger 1001RB-II 700/50W Biamp Bass Head:

                    I bought the 1001RB as a combo with the 115 RBH speaker (GK has since discontinued this combo) and it was a great honeymoon with the amp until the wheels disintegrated about a year ago...bought new wheels from the kind folks at GK, but they fell apart as well...anyway, the head itself is amazing, everything you ever wanted in a head, this thing will provide. Deep resonating lows and clean crisp highs. It takes some tweaking, but the 1001RB pulled some serious midrange growl out of my Stingray 5, which is now easy task!!! I removed the head from the combo, bought a GK 410 amp, contacted GK and bought the outer shell for the 1001RB and now use it as a head/separate amp combo and all is well in my bass playing world. Buy this head and pair it with a great 410 or 212 amp and you will be in heaven...

                    I pair this amazing head with a rare Music Man Audiophile 4x10 cab I found online...what a rig!!(why oh why did Ernie Ball discontinue the production on the bass cabs?? nothing on the planet compares to them...) I get an onslaught of bass players rushing me like an incoming tide after any show, asking me to lift the veil on my rig...(I cover it with assorted fabric for our stageshow). GK has cut their own trail on the engineering end of things, and they're at the top of their game with this head. I used to rent the RB800 when touring with a dancehall reggae crew, and it would flatten the venue with the thickest, fattest and smoothest bass bombs. In recent years, I moved into diverse area's of music, and played dozens of different rigs, ignoring GK because I'd pigeon holed them as a heavy cream diet, sounding best when all the highs and mids were rolled back, a la Robbie Shakespeare Dub. When I came across an add for the 1001RB, I took it for a spin at my local music store.... What a ballistic weapon of mass basstruction! Totally true transparent power!! VERSATILE!!!
