light in your hands and on your wallet

i'm actually a guitarist, but a lot of the best musicians i knew that i wanted as bandmates didn't have jobs and thus not enough money to buy their own gear. i already had a bass cab and wanted just a head. i roadied for one of my friend's bands on a nationwide tour and their bassist had a ridiculously heavy ampeg that killed me every time i had to move it so when i saw that this G-K here had the same amount of wattage and weighed a mere 14 pounds that sealed it right there. this same friend of mine now often borrows this head for shows anywhere there's stairs rather than lugging his big tube head that cost him about 3x as much used. as far as i'm concerned, you can't get a better amp for the money.

I never thought I could get the tone I got with this amp for under a grand. I got amazing low-end and punchy mids and highs. I feel that I played better playing through this amp then any other - even a Mesa!


Great piece of equipment, money well spent.

I bought the Backline 250 about two months ago. I am very impressed by the sound that the 250 puts out. I would definitely recommend this to any serious bass player on a budget.


Great buy, I love it.

Been using it with my Ampeg svt15e 1x15 cab, they go great together. Overdrive is a lot of fun to play around with, the contour effect really brings the sound to life, the equalizer is easy to use and very effective, and the direct out makes it easy to hook into a PA and for recording and that kinda jazz. I recommend at least trying it out at your local GC (my fav store in the world...) before deciding on something else. Great deal for what you get, worth every cent.


Good amp, sweet GK tone, but lacking real power.

By Bryan LeMasters

Quite simply, its what it claims to be - a cheap alternative to Gallien Krueger's RB series amps. It's got the tone, just not much power. It's fine for practices (if the guitarist isnt playing anything to overpowering) and might be passable for small gigs (also depends on cab i guess). It's got two channels, one clean, and one high gain you can overdrive the shite out of. The distortion isn't that great though, it tends to be rather heavy on the high end and just doesnt seem very practical to me. Some people might like to have the gain down real low and have the volume cranked up, for a slight bit of distortion to give it a little more edge for a metal-ish tone though. The four band EQ is quite nice, and offers a wide range of tones you can create, without too much knob tweaking. The contour/mid scoop knob is a nice extra, that sets the range of the mids, enhancing the lows and highs more for a neat punchy slap sound, or keeping it down or off for a warmer smoother sound. It also has effects send and return jacks in front, tuner out (with tuner mute button for silent tuning) and a footswitch jack. Comes with XLR direct out for running to house sound at places where 125watts won't cut it (which is most places) but I have yet to try it out. If the quality of the rest of the amp is any indication, it should work and sound fine though.Soundwise its fantastic though, awesome clean tone I just couldnt find with anything else in the same price range. Beware though, if your bass is of lower quality, this amp will show it, but if your bass has half decent tone, this amp will make it shine like only a GK can.I have seen reviews from people complaining of heat and reliability issues with this amp (and all other GK amps for that matter) and I can at least say I have had no such problems with mine. People have been saying the amp runs uber-hot and overheats a lot, triggering a circuit breaker inside of it to shut it down and keep it from burning up while it cools. Again all I can say is mine works fine, I've left it running for several days straight, when I first bought it, to see if heat would be a real issue with it and to see if there was any other defects while it was still under store warranty. Nothing. No problems at all. It ran fairly cool as a matter of fact. I could however see a problem if someone was dumb enough to cover the top and rear vents on the amp though, but you just can't blame that on the amp. Also some racks might not give it enough room to breathe either, which could create a problem after prolonged use, but again thats up to you to realize you aren't giving the vents room, not the amp. Besides, its a head, its got rubber legs on it, throw it on top of your cab where its meant to be. So my review has turned into a rant about caring for your amp... but the bottom line for this amp, its got wonderful tone, decent set of features, but no real power. If you need a quality amp for something that doent need 800+watts, then this is definitely something you should consider. The tone isn't for everyone, but it is unique and no other brand can touch it. It's just a tad bit expensive for the amount of power you get, but again, nothing can touch it in its price range. overall 8/10

The deep low is what really gets me going. The contour comes in really handy and it provides great tone. The overdrive is really great too.

I have this head with the backline 410 cabinet and I don't like this head very much. It isn't very reliable and when the volume goes past 1/2 way, it gets distortion in the sound. This is a great head for small gigs or garage jamming, but not for big shows.


Ok Bang for the buck

Very decent starter amp or studio amp with plenty of tone shaping ability. The second channel is a very cool feature with the addition of heavy gain. The power is a bit lacking (125w @8ohm) and there is no upgradablity (8ohm is all you get). All in all, a very decent value for the money.
