This amp is amazing. If you use it like an all tube amp. The trick is to turn up the master located next to the boost and leave your Level A down. I crank the boost knob as well but it doesnt matter as much. But the master knob is directly linked to the power section and when you turn that up it really starts to sound amazing. The Level A & B knobs are linked to the preamp. I use to keep my level and master at 12 o'clock and I hated the tone I got and couldnt figure out why. Then I blasted the power section and it's true growl came out. It's also running at 4 ohms (2 4X10 cabs) and it sounds amazing. Beware though, if your master is all the way up, youll probly overheat the head if your level A is above 1 or 2 o'clock. But that's still pretty damn loud. I run it through a GK BLX410 and an ampeg 410he and it sounds great with the Ampeg's horn turned OFF. I hate that tweeter. There's a reason the old Ampeg 8X10's don't even have one.

I thought I would be the guy that didn't get the defective one. Within a few hours of playing it would cut between the clean and overdrive channel at will. Loose connection or something. I returned it. The second one would randomly turn completely off and I was not even pushing the amp, This problem developed before I ever even turned it up more than a quarter of the way.I returned that one for a third. This one has a different font text on the front so maybe it is a newer model without those problems.As for the features, it actually sounds fairly good as long as you dont turn it up more than 3/4ths of the way, it gets pretty nasty sounding then, and its not because of my cab which is the gk goldline 4x10 with 400watts rms handling (ie nowhere near to pushing the cab). I have experimented with the overdrive channel and it is pretty much crap, but then again overdrive isnt for bass in the first place. I have used a boss bass od-1 distortion pedal before and I guess it sounds about the same (they both sound pretty ugly). It sounds alright but alas, I cant give it a good rating because what does that matter when it keeps dying? I havent had mine very long at all, I cant imagine what lies ahead.I have since heard that it sometimes overheats so I am not looking forward to gigging with it, but I guess i'll see how it holds up. Maybe I will put a little fan on top of it. Bottom line is, spend extra for a better 300watt amp head and thank yourself later.

Review

By bassman360

from Harrah, Oklahoma

I bought this amp. and for the first year it was great with very nice sounds and tones. Then the amp. overheated one day and the fan completly quit. I went to radio shack and replaced the small fan with a higher rpm fan which really only makes the burning smell worse. It worked for another 3 months or so and then the power wire on the circuit board burned completly into. If you want to learn how to work on electronic's buy one of these amp's and you'll never be bored.

big problem

By abc123-eFup6

from austin

ive had this amp for about two month now and ive played several shows with it, and at the biggining it sounded like it was going to be a good amp, and i was surprised becasue it was cheep, but a while the head decided that it didnt want to work well anymore, and the overdrive would turn on when it wanted to, i took it to several repair shops and they coulndt find anything wrong with it, i recomend saving up a little more money and purchasing the 400RB-IV head by gk, that one works great and i havent had any problems with it

Best bang for your buck!

By kcblue4u

from KC

I owned this head for a year now and love it! I didn't have a good stack to put it on until just a couple of weeks ago. Man it really rocks now! It took some tweaking until I found that exact tone and sound I have been looking for. I can't believe this head is this cheap with all the features you get!

A 400rb in disguise

By Major Havoc

from eden,ny

See all my reviews

This little bass amp packs some serious thump, smooth tone when match up with the 410glx that I also purchased. The distortion channel makes for some serious to subtle grind to your tone. Simple controls that are very noticable with very little turn of the controls. A simply great bass amp, and at a price that is affordable.

It has its flaws

By thunder thumb

from Kansascity, Mo

See all my reviews

Our church just recently bought this head for me to play on. The sound that comes out of this thing is pretty good at very low volumes. It is not an ampeg but of course it wouldn't be at this price. This head is rated at 300 watts at 4 ohms, but if you plug it into a 8 ohm cab its more like 180 watts. Also this head heats up quickly, too quickly and the fan is on always. This concearns me of it overheating and i dont push this thing that hard. Also compared to other heads it is just average and the boost nob i dont even know why it is there, It dosent help the sound at all. it should also have more tonal options its just basic. I would only recomend this head only if your on a tight budget or if you are not going to play too loud, if you turn it up past midway the sound gets pretty horrible and the more hotter this head gets, beware you have been warned.

300 watts for 300 bucks?

By Phoenix

from Franklin, TN

See all my reviews

Yes, it's possible. This head is a monster and well worth the price. It had a great tone, perhaps the best in its price range, and it handles speakers well. I've had this thing drive a variety of cabs, including the hallowed Ampeg 8x10, and it held up well and pushed the speakers well. I don't use the overdrive channel, because I have the Boss ODB-3 bass overdrive pedal and it sounds better. The contour knob scoops your sound to make it deeper, while the boost knob gives you that GK growl. This cab is such a great value I'm considering buying another one!

solid price performer

By Matt Hays

from Central Arkansas

Here's my $0.02: This amp is a TREMENDOUS buy. If money is NO factor, then sure...buy some other high-dollar rig & season to your taste. But if you're on a budget, I challenge you to beat this one.

My history & setup with the amp: I've had this amp for over 3 years, and use it in my 80's hard rock band. The sound it produces is great. I run it through a 4-ohm GK 810-RBX cabinet, and it can REALLY pump out the sound...all the way from foundation-shaking lows to ear-tingling highs. I've played this rig at large outdoor shows, and it's quite nice...my limiting factor there is simply that I could use more speakers to spread my sound out more (maybe double my rig...one on my side; one on the other side of the drums).

Overdrive: The overdrive channel is quite remarkably good for an all solid-state amp--when you don't try to use too much overdrive. When I use the overdrive as a natural compressor, I run it relatively low, so that when I'm playing gently, there's no overdrive, but when I really bear down, the overdrive growls down & acts as natural compression. My only complaint about the overdrive is that it tends to add a bit too much high-end buzz to the sound, but then again, since I'm not doing a clean/overdriven blend, you kinda have to use what you got.
But the clean channel to get the sweet GK sound...good stuff.
Parting shots about the overdrive & sound: I used this amp for a couple of years with by bass plugged directly in to it with NO stomp boxes and the EQ set straight across at 12 o'clock and the overdrive turned on "lightly" as a make-shift compression & and had a number of people comment on how good my bass sounded.

Downsides: The lack of a built-in compressor is a bit of a bummer, so I run either a compressor stomp box (I have an Ashdown compressor that compresses lows separately from highs) or use the amp's built-in overdrive as a natural compression. I //prefer// a blended sound (clean tone providing the punch and sparkle, with overdrive giving the lo-mid growl/purr, a la Billy Sheehan), but I don't have that at this point...doing that right takes rigging I haven't attempted to do.

"wish list": Ideally, overdrive and clean would have separate EQ settings, but at the price, I simply can't complain. If I want more flexibility, I'll need to pay for it.

Operating temperature: Regarding some people's concern about this amp overheating...the ONLY time I've had this amp act even slightly funny was when I ran the "boost" knob too high. I'm not sure why, but the amp started cutting out at higher volumes (it would "shut down" for several seconds then come back on). Since then, I've keep the boost below 12 o'clock. So other than the boost knob issue, I have had NO problems with overheating. I have used the amp in hot indoor conditions for hours on end, and I have used it outdoors in swealtering heat, driving it HARD the whole time. Folks, the cooling fan may concern some folks, but it does its job and keeps the amp operating the whole time. Don't get me wrong: this amp gets hot to the touch when you drive it hard for long periods of time, but that doesn't seem to affect its longevity AND it certainly doesn't seem to affect its performance.

One tip: buy the rack ears for it (same rack ears the RB-700 uses, I think). The rack ears turn this from hobby amp into a serious once- to three-times-a-month gigging amp.

Short summary: All-in-all, I love this amp, and it has NEVER let me down. GK hit a home run with this one.
This is a solid amp.

Little giant with a good voice

Big and expensive is not necessary better sometimes.This head sound amazing with very little effort and tweaking.It`s got the right controls to help you find your tone in no time.Paired with a decent cabinet will give you plenty of volume for most venues(I`m playing with a 1 X 15 at 8 ohms only and it blast)no overheating problems(just don`t cover the top of the amp where the fan is located,common sense)Again I love the tone of this head,IMO is the best solid state tone in its class,warm and round.The overdrive channel is usable only at low volume for what I play(rock,blues)but for the price, the regular channel is all I need.Small,not too heavy,solid,good tone and powerfull.Hey, this little head is a winner hands down.

Best bucks ever spent...

By Anonymous

from Undisclosed

I bought this to replace a piece-of-crap Behringer 450 B-stock head. This head blows behringer away. I can't believe how good the tone is, and the Overdrive Channel... there's enough distortion to the point of replacing a guitar, it's incredible. You can get any kind of tone you want out of this thing, from death metal to funk and slap. Don't even bother looking at BEHRINGER or ASHDOWN, this head owns them both. You won't regret getting this amp.

A Great Product That Delivers The Goods

By Color blind ?

from NH

See all my reviews

Picked this unit up about 8 months ago and have been very pleased with it's versatiltiy to adapt to a wide range of tonality requirements. From country to 60s rock I can mold whatever sounds I need with this amp. Plenty of power, great clean signal out to PA, and I like the post/pre line out so I can adjust my own sound for various tunes and not rely on someone at the board who doesn't know which tones are necessary. I think it's a great value for anyone who sits down and actually learns how to operate this baby to it's full potential. Great Solid Product That Kicks It

By Nwhitaker08

Great durable head. Been using it since August 2009. Never had a problem with it. Has a great low but punchy sound. The EQ is very wide and can get any tone your looking for. I would recommend a rack case to put this in. The only complaints I have, is how the FX and tuner out is on the front of the head, would be a lot better on the back of it, you always need an open space in the rack to run all your cables through. But great HEAD, BUY IT!
EQ is amazing
Tuner and FX out works like a charm
Balance Line out, and the option to send the mix before or after the EQ is awesome
great, very durable
cheapest head on the market, and sounds the best

You won't believe it until you hear it

By Gavin-UcQYh

from Philadelphia, PA

I cannot believe how good this beast sounds. I just bought it today and gigged with it tonight. It sounded so clear. I am running it with a furman power cleaner and there was absolutely no hiss or feedback, nothing. This model is great for gigging bass players. But, do yourself a favor. This model is rack-mountable, but this unit does not come with the ears to mount it. You have to order them seperately. Or, if you just complain enough the store will take them off the GK display :)

Good starter amp

By Guitar Dave

from Phoenix

See all my reviews

I bought this head along with the 210BLX and 115BLX speaker cabs when I was hired to play bass for a blues jam as part of the host band. I needed something that could take the punishment of a lot of different players along with not being too expensive. The first night, two of the loudest bass players in town showed up to play. These people generally drown out the entire band with their playing because they are either deaf or think bass is the main instrument in a band. I was cringing the whole time wondering when something was going to blow up. The walls of the club were shaking and rattling. The amp held up and has continued to stay intact week after week. I don't like the dinky handle because I can barely fit my hand through it and the labeling of the knobs isn't bold enough to be seen easily on stage. I have to continually point out to the various players how to control the thing. Other than that I am satisfied with my purchase.

not for active musicians!! I've owned 2

By Bandito

from Hot Springs, AR

See all my reviews

Well when I got my first one of these I loved it. Hooked it up to my Backline 1x15 and 4x10 cabs. and it had every thing I needed, great sound, price & quality. After about a year of 9 hrs per week of practice and mild gigs the knobs started to crackle and the fan went out. No prob, extended waranty covered it, and replaced it. I declined the waranty on the second head because I figured if it quit on me again it wasen't bad luck, it was bad equipment. Again, I love the tone and features on this amp but it is not for very active musicians. The next two years had us playing pretty active, at an average of 2 two three gigs per month. Also with 9 hours of parctice each week. The power supply has blown twice since then and I am not buying another backline product again. Keep in mind I carried the head in a padded travel case in a inclosed trailor to and from gigs. It has been well maintained, cleaned and never left out kept in a climate controled practice area.

My friend just got this head with a GK cab and together it blows everything away. This is the half stack for the power bassist. The distorsion channel sounds crazy and is perfect for "Pulling Teeth." The regular clean channel sounds very sharp and you can get a varity of sounds from this beast. Great head, perfect for all music basically.

Amazing Amp!

By bassman5

I bought thsi after realizing my fender rumble 100 was too quiet and had too thin of a tone. Man, this thing has plenty of volume and really fills up a room. I play in a trio, so the bass really needs to cut through and be heard and this thing delivers. The direct out is awesome for gigs, I do with it had a 1/4 out though, because I've had times where a soundman asked me for one and I didnt have it. The eq is great and the overdrive channel is sweet for solos when you want something totally fuzzed out. A great amp for someone who is on a budget and needs something tough, realiable, loud, and with a great tone. Great buy!

By RPMIII

I recently purchased this GK Backline 600. I use it with an Ashdown 115 cab and the sound I get is quite good. Now, it's not the sound you get out of something much more expensive. There's a reason for that. Price. It's the sound you get out of product made for people who actually have a budget. It's a great amp, with great tone for what you pay. Are there a lot better? Absolutely. Does this compare? Kind of.. Should you compare it to amps twice as much? NO! For what it sounds like and the price you pay, this thing cannot be beat.You can adjust everything. Lots and lots and lots of features. Great tone out out of an amp for this price. Feels very sturdy. Knobs have great play.However, mine stopped working about 3 days go. Faulty overdrive channel switch. I love overdrive and all, but I don't want it all the time. This product is great. Just remember that it was made on a budget so that people on a budget can afford it.
