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.

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

By Super70`s4ever

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
