    Unbelievably stellar tone.

    The Roland Cube 30 Guitar Combo Amp really packs a punch! There are lots of affordable guitar amps available on the market today, but none of them have the charisma, style, or finesse of this Roland offering. Representing incredible value in a compact guitar amp, this light, portable, and affordable little beast hosts a 10" speaker with 30W of pure tone quality.

    The Cube 30 includes 8 different COSM amp simulations, including JC Clean, Acoustic, Black Panel, Brit Combo, Tweed, Classic Stack, Metal Stack, and R-fier Stack. The effects section includes chorus, flanger, phaser, and tremolo as well as an independent delay/reverb and 3-band EQ.

    A footswitch input allows you to connect 2 optional FS5U footswitches to control both the effects on/off and switch between the clean channel and lead channel. An auxiliary input enables you to connect other products such as drum machines or CD players, making the Cube 30 a true jam machine!


    • 30 watts - perfect for practice or studio
    • COSM amp simulations
    • Robust effects section
    • Compact and portable

    I recently purchased the Cube 30 after a side by side test with the Vox equivilent model. the first thing I noticed was that Roland's AC30 algorythm was closer to the real thing than Vox's! Go figure... I use mainly the three models on the right of the switch. I have played for over 35 years through most of the classic amps and consider the AC30, '59 Bassman & blackface twin to be the holy trinity of amps. Although the cube does not sound exactly like the originals (no two of which sound exactly alike either)the AC30 & Twin modes do sound eerily like the real amps that have been recorded and played back. This makes sense because that is similar to what is happening in the digital domain. The bassman sound is close enough if you don't crank it too much.My one objection is the lack of real parametric control of the effects - I still choose to use an external delay. The reverb is passable if used sparingly.One of my students brings his boss modeling pedal to lessons and plugs into the aux in on my amp. This works great - he gets his sound and I get mine out of the same small amp. In fact, I plan on buying a second cube so I can use the Boss modeling rack unit and use the aux ins for stereo. That will give me nice 60-watt 2X10 closed back setup.Considering that I mike my amp at gigs, this little amp has plenty of power and great tone, and may be the only amp I will ever need. It is amazing that for less than half of the price (and a fraction of the weight) of a great amp I can have two, and I am perfectly satisfied with the way my vintage guitars sound.

    Pretty good amp. Would I use it for a gig? no. It's more of a toy, little practice amp. Has good tube sound but I really don't believe it is that special. Good distortion and good clean but the effects do not really sound like the real thing. Good if you need a smalll practice amp and what a ok sound.

    Good deal, almost a steal!

    By Shakezulla86

    from Fairbanks Alaska

    I bought this brand new Roland Cube 30 at a pawn shop and was blown away by it. It holds 8 different amp models, including a JC which is the clean channel, lovely good golden sound to it, its beautifull. The FX are fairly good for a combo amp any day of the week and coupled with my Les Paul Studio, its like eating a slice of fried gold. A thing of beauty.I reccomend it for a novice, who has learned a good bit about his guitar before moving away from his first little practice amp.

    Great tone for a small price

    By Rmusictrax

    from Montreal, QC

    I'll be brief, I bought this amp about 3 years ago when it first made it's appearance for practice only and I've actually used it at small venues. The sound is incredible, it's quite loud and the onboard "cosm" sound effects are very very good. It was worth every penny I paid for it. Compact, light and well built...nothing else even comes close for the price.

    great PRACTICE amp

    By multiplebob

    from west virginia

    this is a great prctice amp, the only disadvantage i found was that there is no way to get a different footswitchable rythym and lead sound at the same time! the clean channel is TOO clean for rock rythym playing, and there is no way to switch between COSM channls without going back and turning the knob! which does kind of limit the ability to use it live, but for home use it is the bees knees! sounds great, light weight, and it screams!

    Excellent Value!

    By Switchfreak5193

    from Tulare, CA

    I got this amp after the huge success of my other guitarist with his Micro Cube, and I do say I'm impressed even though I knew what was coming! The speaker delivers volume that's sounds much more like an amp with much more wattage, no need to replace the speaker. Still, I'll have to mic it for bigger gigs. I play it through my Epiphone G-400 (Great guitar, btw) and it sounds great. The EQ is very handy depending on the amp model, for instance, acoustic you need to turn bass really low and mids and highs all the way up to get a good sound. The amp models themselves are excellent. I'm most impressed with the "Metal" setting. The FX are pretty awesome as well. Now, here's the stuff I'm not crazy about-Changing amp models in the middle of a song is a pain, unless you're going from lead to clean. I wish you could use the footswitch to go from Metal to Tweed, to Brit and back again. Then the fact that the controls are not front panel doesn't exactly make that a little easier. Still, if you're planning on playing on 1 amp model per song, and want the whole nine yards-EQ, FX, Amp Models, this is your amp, whether you're practicing, rehearsing, or playing gigs. Highly Reccomended!

    Sweet Little Amp

    By RockNBlues

    from Detroit

    I was looking for a practice amp but did not have much cash to spend. My expectations were pretty low. All I wanted was a decent distortion sound, a little reverb, and a clean channel that was actually clean. Not too much to ask, right? Well, I looked at all the big names in guitar amps and was underwhelmed. There were a lot of gimmicks but nothing that sounded good. Then I tried the Cube 30 and was blown away. The sound was amazing! I love the classic rock sound from the "Classic Stack" setting (model of a Marshall stack) and the bluesy "Tweed" model of a famous Fender combo is excellent. The clean channel has a great sound too. I was skeptical about a guitar amp from Roland -- Star Trek sound effects are just not my thing -- but this little guy won me over. Not only does it have great sound, but also the amp is built like a tank (it even has a metal grille) and has more power that almost anything else in this price range. Definitely recommended!

    I love this little mutha ******!!!!

    By Thunderfingers

    from Lynn,Massachusetts

    I've had my Cube 30 for about and year and a half now,and the more I use it,the more I love it. I'm amazed at the sounds I can get from it. All the effects are outstanding. They're better than the BOSS pedals! My favorite setting is the Mesa rectifier. It's killer! The clean channel is to die for. I've had a number of Fender tube amps,and I like the Cube's clean channel better. Since I've had it,I've sold 4 of my guitars,and I had the people play them through the Cube 30,and every single person was blown away at the tone of this amp. They told me they were going to get one for themselves. It's that good. And for 30 watts and a 10" speaker,this thing is loud! It's built like a tank. I sincerely believe if I threw it off the roof of my second story house,it would still be in one piece and still work. Although I have no intention of doing that! Needless to say,I love this amp. It's the ultimate practise and recording combo. I wouldn't be surprised if some of the pros have used this in the studio. I know I would. You WILL NOT FIND A BETTER COMBO FOR THE MONEY. Best amp in it's class hands down. Kudos to Roland for a great product!

    Excellent for composing...

    By Gladius

    from Tejas

    This is an excellent portable package for keeping a sound fresh for small venues and jamming. It's essentially a no-brainer for moving around frequently. Very tough: I've had the unit over a year... it lived in the truck... and no complaints. All add-ons fit nicely in a gig bag, keep one hand free for the cube and you're on your way. I do not recommend this as the be-all digital effects kit (but do record with it). If that is what you're looking for, go for a Behringer or POD series. Outstanding portable solution for song range of clean & acoustic to heavy chunk and flange-tastic. Can be pleasingly gig-worthy in small venues. I still/always get comments on it.

    nice little amp for sure

    By cogswell

    from The Motor City

    Well I've owned it for 2 years now and I have had no problems at all. Roland makes solid stuff. This thing is great for the money, no questions about it. This is a nice practice amp but it's sound is good enough and is loud enough to jam out with friends and blow your hair back a little. I wish I had bought this for my first amp. What I love about it is how easy it is to use ...and that JC clean channel is wonderful! I hope they make a twin version one day!!

    Versatile Amp, Great Quality

    By TonyTubes

    from Montreal, QC

    This is a fantastic amp. It's effects sound very much like Boss pedals; which is really good. It has a wide range of tones, and is good for someone who plays a variety of stuff. Very good acoustic simulation, and a nice light clean. Turn the tone down on some of the dirty amp settings and you got yourself a perfect "Wind Cries Mary" tone. Do not get this amp if you're looking for vintage tube sound; you will be disapointed. Overall, this is a great versatile amp.

    from South Dakota, USA.

    The effects are great, and you can get some really cool delays and get some Pink Floyd sound out of it. It's almost like a bunch of amps in one. You can do acoustic, blues, blues rock, classic rock, hard rock, and metal. It's also very compact, but wow, is it loud. When I was playing it in the store, on a Fender Stratocaster Standard (which is what I play at home) when the sound level was a little less than halfway, it sounded the whole place up. It seems more than loud enough to play a gig or whatever. You can have it on a low sound level and still get a big distorion. This is a superb amp, for not that much money.
