The GK 700RB-II comes equipped with everything you need. Input volume control with -14dB pad for active instrument, tuner mute switch, contour and presence knobs, 4/5 strings selector switch, 4-band eq, Boost knob, a separate woofer and tweeter volume for bi-amp operation (480 W for woofer + 50 W for tweeter). Solid-state electronics. Two 1/4" speaker output and two 4-pin speakon output. DI output with pre/post switch and level knob.

I can get every sound i need from this head. Actually i have to put just a little bit of boost and cut on the EQ to get the sound i want. The sound from GK 700RB-II is almost always crystal clear. You get to hear the articulation on all the notes even on the low E and B. No irritating glassy highs. What i like about this GK head is the Boost knob which really helps getting the 'growl' i love. Never try the bi-amping though but even with normal operation, i already get what i need.

Everything is self-explanatory and straight-forward. If you still don't get it, there're even little curve diagrams on the knobs to show you how each knob adjusts your sound. One minor inconvenience though.. the fuse is a pain to replace. But i never have the fuse short out on me before.

So far I have two knobs problem with this head already... (still expect more to happen). After 1 month of buying it, the woofer volume knob just wouldn't work. I have to have my tech taking it out and solder it back in before it works properly again. Then about 6 months after, the input volume knob got dirty and i have to replace it. So i do expect some more problems with the rest of the knobs. But other than that, the head is built to be rugged. Never had any problem with other parts. I've been touring a lot and only encounter the two knobs problem.

Volume, Boost and separate amp levels give this amplifier many ways to deal with volume, create midrange growl without destroying the effect of the tweeter. I was at first concerned about the power, but after playing it with my buds was blown away. This amp as enough power for just about any situation played through good cabs. This amp is not stereo. It is solid state. The effects loop is good and the direct out is very usable. The 5th string voicing is AWESOME. This amp has separate voicing for basses with a low B. If you've ever experienced a flat sounding B-string, this amp is the cure. B rings like the E or A with the 5-string button pushed in.

I use a Roland V-Bass effects pedal / synth. I play funk, rock and jazz in a WIDE variety of voicings and sounds. This amp reproduces sound in a SPOOKY clear way. In fact, I've found the sound quality is actually intimidating - it's almost too clear. Comments from the drummer: "It sounds like you just replaced your strings." "Du-Hamn...you have got to be kidding me." Comments from the guitarist: "The low-end is definitely awesome. Dial-out some of those highs will you?" :-)

I find the controls idiot proof. And I'm uniquely qualified... Actually, the EQ is very easy to use and unbelievably responsive. You can dial in a midrange growl just by pulling the low-mids up to a 9-o-clock position. I do find the competition between the high-end EQ and the separate tweeter amp (in bi-amped mode) to be a little difficult to work with because they really must be used cooperatively to achieve the desired effect. I can't bring myself to reduce the rating just because of this though, since the bi-amp feature brings so much else and I wouldn't change the EQ config at all.

DON'T KNOW. It feels strong and extremely solid. Due to its size I plan to rack mount it for safety.

This amp features active and passive electronics imput and a 5 string and four string selecter. Gallien Krueger is one of a kind when it comes to bass amps and there features. For out put you can run 480 watts through your woofers and 50 watts through you horn using the amps special bi amping technology yes you herd me no more distorted tweeters. you also get a five band Eq on this modual with two different settings for your mids. too add flavor the amp features a contour knob too scoop out the mids and a presences knob to give some punch to and spark to your fingers. Last but not least my favorite feature is a boost control that allowes you to boost or cut you tweeter or woofers effectively allowing you to add that hard too get growl that some of us players love.also it has both 1/8th outputs and speakon outputs.

Can we say clear as a bell deep warm metally, what you desire can be dialed in this amp with great of ease I am truly amazed at the versatillity of this truly great head. personaly I play through a 400 watt 2x8 1x15 and a horn svt pro ampeq cabinet with bi amping ability, and a fender deluxe active bass and I could not be happier with the sound.

I have yet to gig this head and to tell you the truth I wonder if the achillies heel of this amp is the fact that it is small and light and would look more convincing on a desk top then on stage, but It is rack mountable so it must mean buisness. Other than that the amp is solid and fan cooled so I dont think it will die on its own will alone, ill up date this review when I inevitably drop it but four now it gets a five
