The Gallien Krueger 700RB is a bass guitar bi-amp head with a big sound and a lot of versatility. The amp has a lot of options in terms of connections, as it consists of an XLR output, as well as 1/4" connections for your instrument input, a send and return and for a tuner, so you're really getting the works with this amp. It also has speaker outputs in the back for sending this to a speaker cabinet. There are actually two amps in here to be used at two different wattages I believe, and while I'm not sure exactly how much it is, it can really get loud if necessary.
In terms of control, the Gallien Krueger 700RB offers up a whole ton of it. While it might seem confusing at first because of all the parameters, I think you'll definitely find that it is helpful in the end. The front panel of the amp has sections for direct out, input, voicing filters, active equalization, bi-amp output, and patch bay. Each has their own set of parameters to work with. The EQ is a four band, while the voicing filter section includes contour and presence control. There are then knobs for boost, tweeter, and woofer in the bi-amp output section, and one for level in the direct out section and one for volume in the input section. As you can tell, there is a lot going on, but once you break it down it really isn't too complicated. The manual is definitely put together well and could potentially be useful for all users.
I've used the Gallien Krueger 700RB in the recording studio as an engineer, not the performer, as I'm primarily not a bass player. The amp was owned by the bass player on the session, and I really only got to use the two times that he brought it in. However, during those two sessions we got some seriously awesome bass tones out of this. He was playing with a Rickenbacker 4000 bass, so we got an extra punchy sound as well. The great part about this amp is that you really have total control over your sound. We took both a direct signal using the XLR output on the amp and also sent the head to speaker cabinet.
For an amp of high caliber, the Gallien Krueger 700RB is actually a great deal. I thought it would be a much more expensive head than it is, which I think is really saying a lot. I'd encourage those interested in getting a new bass amp to definitely keep the 700RB in mind, or at the very least check out the very impressive line of bass amps that Gallien Krueger has to offer.
I use the GK 700RB for over two years. Never had any problems.
I like the sound, but especially the very fast response of the power stage. Amp very complete. all adjustments necessary for a great versatility and connectivity are!
The only problem is the breath of the Post EQ DI. In preEQ, no problem it is very quiet.
Anyway, I use ever PostEQ they ca not like our friends ingestion sounds!
The value for money is even though it may seem a bit pricey (about 1000Euros in 2001)
There are better amp but as it is more expensive.
The head is very small and is 7Kg which is very reasonable, ideal for bass players who are a long way in small trucks / cars.
With the experience I have of this amp, I would like to take it back or le700RBII (100W more ...)
But I want to spend a hybrid amp (tube pre / power transistor).
In any case, the best amp I tested compare a Hartke 3500 has a 350 and a SWR SVT3 (yet!)
Transistor amplifier with transformer-ring: lighter, more compact, more reliable than conventional transformers, more cash peaks, but more expensive
Power: 380 W + 50W for the woofer to tweeter
Speakon connectors if you want to benefit from the bi-amp on the speakers GK, otherwise an adapter Speakon / jack (not picon / beer) will do.
settings: gain, filter contour / presence, four bands of active EQ (like four independent amplifiers) boost (simulation sturation lamp very successful), settings for bi-amp, effects loop (not adjustable) + section DI box theft, ground lift and pre / post
is very complete, there is everything you need
All knobs at noon, for me it's nickel
I am not a fan of voicing filters (contour, presence, switch 4 / 5 strings) so I put them in the middle
physiological adjustments are very effective but if you appreciate the sound balance of the instrument, the receiver set is perfect right. I like the growl of the lamps (to have long played on SVT) and I must admit that the act of placing transistors turned me does not a priori. I was captivated by the boost that is easy to control while giving his death: combined with the bi-amplification is a major strength of this amp!
a small flat on the calibration of the gain control input: do not hesitate to raise the level almost to the bottom for a passive bass if you want to enjoy the full power of the beast ...
All styles are allowed, it is the most versatile amp I've ever
I use it for four years in a variety of configurations, with an enclosure and an enclosure GK 2x10 peavey 1x15. incident. No need to play very hard to find a place in the mix. With a music man sting ray 5, it forms a perfect couple (you know flea ?...) I would do the same choice without hesitation
