Great Practice Amp

By Greg from Willow Grove
Music Background: Jazzer-wanna-be

This is a very nice practice amp, especially if you need clean sounds-like I do. This amp is great for Jazz, but has enough effects to enhance any tone. Is a nice size and weight. I like it!

Great practice amp.

By Ray from Boston

I bought the Cube 10GX a few years ago. Was troubleshooting some vintage guitar equipment, and needed a clean amp. Worked great for troubleshooting. Also great for practicing. The effects work well, but I frequently used pedals instead.

Currently, for practice, paired this with a Katana Go plugged into the AUX input. Sounds amazing! Works great with acoustic, ambient, rock, and metal. Very easy to transport.

Not Good

By Dave
Music Background: playing guitar professionally for 45 yrs.

Just got this thing and I gotta say the only thing good about it is the clean channel. The crunch channel is fizzy and fuzzy and boxy with no way to dial it out. The lead channel isn't much better. Its Loud, so what. I don't think anyone buying a practice amp cares if it's really loud. If 0 is off, it goes from low volume 1, to loud between 2 and 3. It doesn't gradually get louder, its either real low, or wham its loud. I don't get the reviews of people saying this sounds great. Its barely ok at best. Now, I know what it is, and what to expect, but when my really old Line 6 spider 1x8 sounds better that's a shame. I bought it because I own a Katana gen 1 I bought brand new way back when. I've had Roland gear and always considered it quality. This isn't. How this passed QA for sound quality is beyond me. I have a feeling all these practice amps sound like this after listening to video reviews of Yamaha THR's at the same price point. I'm hoping my sales rep will take this off my hands and I can get something else. Are the cheap Fender Frontman or Marshall Mg series better? It still has to be somewhat inspiring to plug in to or its useless really.

Sounds fantastic.

By Edwin M.
Music Background: Guitar and multi-instrumental musician.

For such a small amp. It has a great sounding speaker. Effects are limited to delay & reverb. Which you can not control. But they do sound good. For such a small amp. It has a great full sound. At a low or high level. Anything that inspires me to play has me using it over and over. I like.

Solid Little Amp

By Chris

Plenty loud for its size. Definitely fills the room with sound, despite the small speaker. The companion app provides access to a wide array of tones, and the onboard effects are quite useable. The only downside is that these models no longer have the capability to run on batterys like the models of old...

Can't Change the amp model using Android.

By Scott R. from WV

Amp works but all "amp types" now have the same amp model assigned to it, which I cant change with my Android phone or tablet ( I was able to get it to work once.) Now, whenever I try to change amp type, I hear a crackling sound and the light continues to flash. Tried multiple times with a different cable. I guess I'll have to send it back.

Great practice amp

Amazing little amp

By Freddy
Music Background: giging musician

Great tone with plenty of oomph....You can gig with this amp in a small or maybe medium size venue depending on the acoustic space. you can also set a somewhat mellow tone for blues or jazz or make it scream for rock. you can also carry the amp with one finger its that light. Finally this is simply a great little amp with a huge personality and doubt anyone would be sorry for purchasing this baby.

Perfect for me

By Frank M. from Hudson Fl.
Music Background: Been pickin since the 60s, blues, rock

I build and play cigar box guitars with magnetic pickups,single coil, humbuckers sometimes piezo's. This amp sounds great. Plenty of volume plus the effects are right on. It's worth the money. With 3 amp settings,clean,crunch and lead there's a lot to have fun with. I'm enjoying this amp. Plus it's easy to carry, nice and light.

Unreal.

By Don L. from Redford, MI

I can't believe the quality of the sound for such an inexpensive amp and only an 8" speaker. BUT...it's surprisingly good. I don't even know or use the "COSM" thing. I think it's just marketing doo-doo anyway. But the rest is all I need. More than enough. 3 voicings with 3 EQ bands and some pretty nice effects, especially the chorus. It's incredibly good considering the price. Nice full sound and plenty loud. Even at 4.

GREAT FOR LAP STEEL GUITAR

By AZ G. from Arizona
Music Background: Professional musician

I got this mainly for lap steel guitar. All I need is reverb maybe delay and a good sounding clean amp.
This amp gets plenty loud enough to play with a small group no problem. The quality of the
sound is excellent. You get Bass, Mid, and Treble adjustments. The feature where you can select with your cell phone from a bunch of amps three amps you like it just mind boggling. My choices are Roland, Blackface, and Tweed. This is so cool. It is missing the effects you find on most Cube's but it is not an issue as I have pedals. I have never had a Roland Cube amp I was not pleased with. This amp is no exception.

10 watts, 8 inch speaker, great for 'Low-Volume' recordings with the "G1-FOUR!"

By Sweetwater Customer from Mont Vernon, N.H,
Music Background: Guitars, woodwinds, percussion. Classic Rock, Jazz, & Latin Music.

I used the "Q2n-4K" to record the new ZOOM G1-FOUR through the CUBE-10GX 1X8. Much bigger sound! (I was recording with my 3watt-CUBE, but it sounded "tinny",I wanted a bigger sound, more like a 12 inch speaker). I was pleasantly surprized with the 8 inch 10 watt CUBE! I set it on "clean", and it sounded a lot bigger than the little 3 watt CUBE! I let the ZOOM G1FOUR do the rest, tone-shaping, etc. It sounded more like a 12 inch speaker-cab!

Excellent service

By Turguy G. from NY

Cube 10W is a 100w like monster. Super clean and mega gain. Way better than my expectations. Thanks for a real fast delivery and a great customer service you provided before and after the purchase.

it's more than you think

By Sweetwater Customer

besides the quality, sound and build roland is famous for, this sucker's loud. took it to band practice (sans drummer) and not only was it loud enough, i had to turn down. very impressed. btw, we play pop and country rock.

Pleasantly surprised

By Bill A. from Bristol WI
Music Background: Several years in a band. Singer, rhythm guitar and bass. Fender telecaster. 60's Rock and Country. Solo artist in concert with a drummer.

I have used both a 35 watt and 65 watt cube coupled together on stage with a band and always impressed with Roland versatility.
My specific use for this small and robust amp includes traveling in our RV so the low power AC adaptor and overall weight filled the need.
As with my previous experience, I am completely satisfied with a product that ticks all the boxes.

Roland 10W amp

By Jon S. from Minnesota

All I can say is how surprised I am with the power this little amp puts out. The effects are out standing the low, midst, and high are crisp and clear and to think it only weighs around 5 pounds. Not only does this amp work well with my electric guitar, it also works great with my acoustic and select the clear setting with just a touch of chorus effects really brings my Martin alive and clean sounding. I am impressed with my Cube amp for a little package it packs a big punch.

Fantastic little Amp

By Paul from Missouri

I am not much on writing reviews but I got to say that this Roland Cube 10GX is Fantastic.
Has great tone and easy to move from room to room.
It is also pretty load for its size.
The effects are alright but nothing to brag about.
Chorus is load and very noticeable, The Delay is not very good. Not very present and There is no way to turn sound up on delay.
Other words it is weak.
Reverb is OK but spring reverb is a little to springy
Other than that it is a great little amp and I like it. Its a keeper !
I have been using a small pedal board with the amp instead of the on board effects and the amp is amazing.
A lot better than a few others I have tried.
I also love the Cube Kit app where you can change the Amp sounds on each channel. Another reason I am keeping the Amp.

Awsome small guitar amp

By David from Houston Area
Music Background: Playing many years

This Cube guitar amp is amazing. It's sound is so much bigger than it's actual size. This little thing will get surprisingly loud and continues to sound good. The clean channel is very clean and clear with strong bass tone and wonderful treble. If you mic this little amp you could actually use it on stage. I bought it as a practice amp that I could move from room to room, but I'm thinking I might try it during one of our band's rehearsal, it sounds so good. The little 8 inch speaker will rattle the windows. It really gets loud if you use the "crunch" or "lead" channels. The effects are as good as any combo amp regardless of size. If you have someone that's learning to play this is a perfect guitar amp.

Roland CUBE - 10GX

Awesome sounding little practice amp! You could get away with using it at a local gig if you mic'd it through a P.A.

Cube believer

By Jason from Ohio
Music Background: 27 yrs experience, guitar and pedal steel

This amp is simply amazing, blindfolded, the size would surprise you. Tone is impeccable, the app to add more amp tones broadness the horizons. I even used it for pedal steel, loaded the bass amp from the app, for the simulation of the 15" Speaker adjusted the tone, added spring reverb... Amazing little steel amp! My only dissatisfaction is the reverb and delay are either or... You can't have both, I always run delay in my chain along with reverb, this I can't do. I've got an old dusty pedal I can run in front lol. Highly recommend, otherwise I'd be a 5 if those little tweaks were made

As soon as I got the Cube, guitar stand and cable home, I hooked up and played. Sounds great! I tried with both my acoustic hybrid (Cort) and my Schecter (Dan Donovan) electric, and was very pleased with what I heard.

Poor sound quality vs the micro cube

By James

I have a 10-year old micro cube, which I love. Bought a new MIM strat recently and wanted something with a litttle more power. Got the 10 GX and was really excited. Clean channel sounded really nice. But both the crunch and lead options were very poor. They sound much better and clearer on the micro cube, and honestly it"s not even close. The micro cube was that much better. Perhaps the 10 gx needs to be played lout for it to open up, but I doubt that as well since the sound quality was just as poor through a pair of high end studio head phones. I"m returning the item and am enjoying the sound of my 10-year old micro.

A piece of advice about Crunch

By Michael from Mississippi

At one time, I owned a Roland Micro Cube and had a blast with it, so I was excited to get the Cube 10GX. I experienced with the settings for quite a while and was a little disappointed it didn't have the phaser effect like the Micro Cube. But what really concerned me, however, was the stock Crunch sound. It's supposed to emulate a 1987 Marshall head, but I thought it sounded really bad...too boomy when hitting chords and too tinny when playing individual notes. I tried all three of my Gibsons (Les Paul, Explorer and Firebird), to no avail. My Micro Cube sounded better than this.
I was getting more and more frustrated when I remembered the app gives you more options with simulated amp modeling. So I downloaded the app, followed the instructions and downloaded the Orange Stack model into my Cube. BAM! That was it...that was the crunch I was looking for. Maybe I'll get around to trying the Brit Combo and other amp models, but for now the Orange Stack is hitting the spot.
This is a great little amp, very versatile and good for small open jams or practicing in your bedroom. It's plenty loud, too!

Great little practice amp

By Gino from Jersey
Music Background: Very experienced

It arrived yesterday and tried I it right away. Sounds great and exactly what I was looking for. I've been playing in bands for decades so it's not just a kid's 1st amp. I wanted a small. light, good sounding practice amp that I could sing along with no mic on my vocals (for solo rehearsals). And I was primarily interested in that good, clean Roland sound. The solid crunch and OD settings are a bonus. It's kinda perfect. Thank you Sweetwater for steering me the right way!

Fun little amp!

By Nikki from Upland, CA

As a novice acoustic player buying my first electric guitar (the Squier Jaguar), I had no idea what to look for in amplifiers. Fortunately, the very knowledgable (and patient) Ashton Vaught listened to my mental wishlist and recommended the Cube - and it's perfect! Great for noodling in my home office with some fun sounds to play with. It inspires me to play even more!

On the Fence

By jack l. from chicago, il
Music Background: insane amateur

I purchased the Cube 10GX based on its great reviews and a recent guitar magazine article. I have played through tons of practice amps and they all sound, well, terrible in my opinion. I am used to playing through amps with 12" speakers or speaker cabinets, and it is very difficult for my years and mind to adjust to the sound of these amps. But this amp is different, I am very pleased with the sound, especially after uploading the additional amp models.

The pre-amp section and the COSM amp modeling, and the ability to download/upload a variety of amp models is pretty cool. The headphone out sounds very good and the pre-amp section records well through this connection.

The default clean sound is pretty good. I did not like the default crunch and lead sounds and changed them using the phone app. Have no idea at the moment which lead sound I am using but it sounds great.

The effects are controlled with a single knob. Would prefer discrete knobs and a bit more control but again, this is a practice amp! The effects do sound good.

So, it is what is, a practice amp. But I have not heard a better practice amp and being able to download/upload additional amp models that match my particular likes is the icing on the cake. And the little guy is well, really little.

Amazing Sound

By Sweetwater Customer

A friend had a Cube 10GX and I got to play it for only few minutes. That was enough to convince me that it was different than other small practice amps. I ordered one the following day. I can't say enough about how good this amp sounds. With the Bass, Mid, Treble controls combined with the Effects I can create a great sound that gives up nothing to the big guys. While a 10 watt amp will not fill a stadium, it is certainly adequate for a small venue.
There is no other amp to my knowledge that matches the 10GX for the price. I would buy it again in an instant. Nice produce!

Cube 10gx

By Sweetwater Customer

After downsizing from a much larger amp, I am very happy with the Cube. The amp models that it has are nice . I use the acoustic model a lot. I also use my IPad with Amplitude run into the aux in plug to create pretty much any sound this bedroom guitar player could want. My wife is a lot happier now that I have an amp that when you turn it on the windows don't start shaking.

Great practice amp

By Kyle F. from Ann Arbor, MI USA
Music Background: Hobbyist

Simple to use and no-frills, but sounds great. No buzzing. Warm sound. It's great for practicing because it sounds good even with the volume low.

The built-in effects are subtle but effective. Not great if you're looking for heavy distortion.

I tried a Line 6 Spider IV 15 and the cube was a massive improvement for just about the same money.

Sweetwater's Customer Service Is The BEST!

By Al S. from Fishers, Indiana
Music Background: Professional Musician since 1964

Due to a second heart attack, I recently "retired" from playing gigs, but I still wanted to woodshed on my six-string Gibson ES335 ... "never too old to learn!" I spoke with my Sweetwater rep, Marcos Sanchez, about the little Roland Cube-10GX guitar combo amp, since I've been playing mostly bass for the past 30+ years and didn't own a guitar amp. Marcos spent an inordinate amount of time on the phone and email explaining the little amp's features to me. After deciding to buy it, I placed the order via phone and the next morning the Cube showed up on my doorstep! It's the perfect practice amp -- everything Marcos promised. At 70, I'm able to work on technique, charts, SFX, and more without disturbing anyone else in the house! Great little amp but even greater customer service from Marcos and Sweetwater!

Best little practice amp for the money!

By curt s. from Sheridan, WY
Music Background: Hobbyist

I have tried about five different small combo amps over the past year. I have tried amps prices at $99 and amps priced at $299. This little Roland Cube 10GX is the best amp I have tried. It is simple to use, has a great sounding speaker, crystal clear clean channel and very usable crunch and lead channels. The reverb and other effects sound great as well. If you are looking for a simple, uncomplicated, easy to use, great sounding portable amp then I recommend the Roland Cube 10GX highly. This is my third Roland amp, I also have the Micro Cube and the Micro Cube with four speakers, I am sold on Roland amps, they are all SUPER amps for the money, you won't be disappointed!
