MicroCubeRX.jpg


So I’ve had a new amp for the past few weeks. I really wanted to put it though the paces and let any “honeymoon period” fade until I posted about it. My Vox Valvetronix AD15 has just about given up the ghost and I was on the lookout for a modeling amp, tube or SS for at home practice use. Something for late nights or some more volume during the day if need be.I also wanted something I could use with my IPOD to jam along with. A few months ago I saw the demo and announcement of the new Roland Microcube RX and had been waiting to try one while I tried some other amps. Finally the RX became available, I tried it, and brought it home for a test-drive.

OVERVIEW

I’d not been a huge fan of the Cube modelers that I’d tried, which was basically all of them including the original Microcube. I found them overly digital and/or poorly matched for the speakers they were using (i.e lower volumes just sounded awful). The RX is unique in that the modeling (amp and effects) has been tweaked over previous versions, its uses 4 proprietary 4” speakers (4x4) that were designed specifically with this amp in mind, is stereo (2.5 watts per side), and has a Rhythm machine built in (a drum machine with 33 pre-sets, adjustable tempo, and a metronome). It also has the AUX input for an IPOD/CD player, can handle a mic, built in tuner, etc. And is selling for $229.00! I figured this thing would be a dream practice amp with all those features, if the dang thing actually sounded decent.

The models are typical for the CUBE series: An Acoustic sim, Roland Jazz Chorus, Fender Blackface, Vox AC30, Marshall 1987 Plexi, Peavey 5150, a MESA Rectifier, and a Mic setting for plugging in a Mic and singing through.

Effects are divided into two areas: a Delay and Reverb section (choose one or the other but not both), and the modulations are Chorus, Flange, Phaser, and a Tremelo (one usable at a time in combo with delay or reverb).

There is also a “boost” button. The manual basically is useless here, only telling one to try it as it will vary in effect and tone with each amp model, and it does. At times it sounds like you are kicking in a BOSS OD-1, at other times a DS-1, and others a Tubescreamer or even a mid-cut/clearer overall EQ. For some models it actually lowers the volume instead of increasing it. Very strange. However I’ve found it VERY useful for tone-shaping.

The Rhythm machine has 11 different “genres” (rock 1, rock 2, blues 1, jazz1, etc) and there is a variation switch that adds in two more drumbeat variations to the selected “genre”. There is a separate volume control from the modeling section, on/off , and a tap-tempo for this section to vary speed. It also has a metronome/click setting. A footswitch (not included), can be plugged into the back to vary tempo and turn on/of .

Finally it includes a well written if brief manual, the power supply (it also runs on batteries), and a carry strap. The amp back is closed and overall it’s very portable. Prolly about a foot or so high-10 inches wide…8 inches deep or thereabouts.

Re: A long drawn out amp review-

THE MODELS:

Acoustic Sim: I’ve yet to hear an actual good Acosutic sim. This one is no different. Boring. Doesn’t sound very good. I didn’t buy the amp for this though, so I don’t care.

Jazz Chorus- I had a JC55 for a couple years back around 88 or 89, and I’ve played the 120s as well. I’ve always loved the clean sound of one. And still do. The modeling on this RX brought me back. It’s surprisingly good, especially with the stereo power amp and chorusing on. For you metal guys, it nails James Hetfield’s clean sound on MOP and AJFA (which were JCs) I found myself re-learning the opening of “One”. I love when a tone inspires me that way to play something I haven’t in so long, or attempt something I’m familiar with but never bothered learning. Kicking in the boost button actually yields a nice low gain bluesy crunch. Not sterile at all.

Fender BlackFace- Modelled on a Twin I’m sure. This model as well, is a great approximation of the real deal. Set for ultimate clean with a quick 1 repeat slapback echo had me country twanging- and I NEVER country twang! Lol. Wonderful for a Rockabilly type tone too. Increasing the gain brings it into classic twin blues territory with nice spank and bite. Kicking in the boost lowers the volume a tad but sounds like you are goosing it with a good OD pedal-thicker in the mids, highs get a little compressed, but not overly so.Very cool. While the Vox AD series may be warmer and more tube/real amp-like in feel, I found this little MCRX to be more authentic in voicing and hence more fun to play.

VOX-AC- I suspect this is modeled on a AC30 TB. Though I think it sounds more like a combo of a AC15 and a 30TB. It’s a little cleaner and less middy than a 30 TB. But still nice Vox chime here. Again the voicing is particularly good, and GASP, I found myself even picking out the opening to Day Tripper (not a fan really of the Beatles). Crank the gain, and you get into a classic Vox crunch that again doesn’t have a lot of that digital artifact tone. Pop the boost in and with some tweaking you can get near that early Blackmore (Hush!)/ Rory Gallagher type tone. Still chimey in the highs, but thicker in the mids and a little smoother/rounder.

Contd.
 
Re: A long drawn out amp review-

Marshall 1987 Plexi- High $ modelers or low $ matters not: I am thoroughly convinced that old Plexi’s just cannot be modeled accurately. Line 6, Roland, Vox, whatever. They are never right. The Line 6 is always thin with no balls and digital compressed highs. The Vox is boomy and the mid voicing is all out of whack. This Roland is closer to the line6, with a bit less digital crap going on. Its dark, has no crunch or balls, and the highs are strident. At first I really hated this model. In recent days been able to at least get a usable sound out of it with some strange EQ settings and careful tweaking of the gain control and the boost function (which actually seems to clear the sound up a bit). It’s better than line 6, but that’s not saying much. Higher volumes (unfortunately too loud for my neighbors tastes) help to open up the tone a bit.

Peavey 5150- I bought the amp thinking this would be my “go-to” channel for the typical NWOBHM and other Crunchy hot-rod Marshall type stuff I play a lot of the time. Like the Plexi, this was a big disappointment. A real 5150 is obviously based off a Soldano, and this model sounds like the weakest, most anemic and compressed Soldano you’ve ever heard. I’ve played a SLO, I’ve played a 5150. This model sounds like neither. Like the Plexi model it’s dark, full of digital squish with no low end and no crunch. Here, Vox (especially) and Line 6 modelers hold a big edge. The boost makes it sound even MORE middy, (in a bad way) and muddy. I can dial in a decent almost liquid solo tone with a little bite on top to it, but crunchy powerful rhythms still elude me. Like the Plexi, pulling back the gain significantly and really opening up the volume on the amp helps with getting a better tone-albeit not 5150-ish in the least

MESA Rectifier- This was a surprise. I generally cannot stand modelled rectifiers. They often have that mushy low mid nu-metal sound for downtuned music as the default tone, even though rectifiers are capable ofso much more. Well the modelled sound is not bad. While it has some of that Mesa fizz on top, the sound they modelled seems a bit more tight and less flubby in the lows. Its not bad at all, but still not my thing. Now, the real treat is when you kick in the boost switch- Mids get pumped up, the lows get super tight, highs slice without being buzzy, and it gets this extremely crunchy aggressive tone that I’ve dialed into some real Rectifiers before. Pull the bass and treble back to 11 oclock, push the mids to about 2 oclock control, and voila: instant Iron Maiden’s Piece of Mind studio filtered tone. Raw crunch. I’ve plugged in the IPOD and jammed along with the album, several times and its REAL close. Very cool tone. Unfortunately that is all this model is capable of. Like the JC, it does one sound, but man it does it **** good. While I’d still prefer it a bit more marshally sound on a day to day basis, this has has worked out OK as a replacement for what I thought the 5150 would handle.

Re: A long drawn out amp review-

EFFECTS:

First off, this isn’t like the Vox or Line 6 modellers where you can adjust and tweak parameters like it was the real thing. The MCRX has no level or blend control. However it does seem that Roalnd has modelled several usable classic effects settings and as you turn the kob, you cycle through a small handful.

The Chorus is great, it is modelled on the analog Chorus of the JC amps and sounds more like a CE-2 (yay!) than a digital chorus (boo!). As you tunr the knob you go from a slow lush chorus into a faster slight vibrato to a heavy fast swirling effect. Me personally I just abrely turn the thing on- I love that slow swirly analog chorus stuff. The chorsu model on the Vox amps I never use as it sound slike a digital chorus into an effects loop-this Roland sounds like a CE2 plugged into the front of the amp (double yay!)

The Phaser is very much like the chorus, going from a slow VH1 sweep, to a Kashmir-ish swirl to faster “They Call me the Breeze” into a quick 70s clean funk rhythm type phase or Dave Murray type thing. Totally stomps (no pun intended) the phaser on the Vox modelling amps.

As a carefully used phaser is one of my few “must have” effects along with a analog chorus type pedal. I’m a happy camper.

The Flanger- I admit I’ve used it little. I think this particular effect is where the lack of adjustment hurts. The resonance is way too high for my liking and you cannot do anything about it. I think the Vox flanger model has it beat hands down for getting that cool Barracuda chugga or Unchained vibe.

The Tremelo- again, don’t really use it. Never have liked the trem effect but the Vox modeller seems to have a pronounced edge.

Delay- as I mentioned previously the quick slapback is hella-cool. As you turn the knob you not only get a slower delay time, you get more repeats. I do not know the amount of ms , but it sounds much like an old analog Boss delay. The longest delay time setting and number of repeats is actually about the limit of what I ever use (e.g. the beginning to JP’s Victim of Changes), So I’m quite satisfied. The Vox has more adjustability by far.

Reverb- This is a powerful tone shaping tool on this amp. It can make or break a modelled amps sound. Things like the Plexi and 5150 benefit from little to no reverb otherwise they RELLY get dark and mushy. The Rectifier, Twin and JC get warmed up.It can get pretty cavernous, but I usually keep it set pretty low even on the models that benefit. The Vox again has more adjustability, but I like this reverb, set it, and forget it. It sounds good with no tweaking whereas despite the increased adjustability I could never get the Vox sounding how I like it.

RHYTHM MACHINE

Ok this thing is cool. Within about 10 seconds of using it the first time I had the basic drum pattern of Livin’ After Midnight going and off I went. Switched to the next pattern, hit the “variation” button, hit the tap tempo a few times, and there was “Runnin’ Free”. As I said before there are 11 “patterns” or styles and 3 variations of each. Then you have the tap-tempo as well. My Girlfriend had a little fun with one of the “Dance” patterns and the tap tempo, and had me dancing with her in condo for a few minutes. She doesn’t know a pickup from a tuner, hates guitar music , and badgers me to no end about the “wheedly wheedly crap” I play - but she even commented how cool my new “speaker” was (her terminology which means “amplifier”, lol). I will say using the tap tempo can be pretty tricky to get the speed right compared to say, a delay pedal. I wish there was a variable “speed” knob instead.

THINGS I DON’T LIKE

Besides the very disappointing Plexi and 5150, as well as the tricky tap-tempo, I do wish the knobs were a bit more sensitive. Often you are turning the knob slightly and you cannot hear any noticeable change, then all of a sudden there’s a sizeable change. This is especially apparent in the effects, as well as...

The Volume. This amp is incredibly loud for a 2.5 watt per side amp Seriously.. And again this is where I wish the knobs were more precise. It goes from “not quite loud enough” to “whoa..the neighbors are gonna be knocking on my door” It’s a fine line. At 9 o’clock it is too loud except for when the neighbors are not home. At 9 o’ clock It easily drowns out our TV set to 75% max volume. These little 4" speakers are VERY efficient.

It’s all digital, so it lacks that warmth and some of the dynamics of the valvetronix amps. It sound less like a “real” amp and more like a modeller.

I sooooo wish it had an Marshall 800 model.


THINGS I LIKE

In addition to everything I’ve mentioned, I’ve gotta say those 4" speakers are indeed tuned well to the amp and cabinet. It sounds REALLY good at very low volumes. It sounds FAR better than the regular MicroCube or the other Cubes I’ve tried (20/30/60)

The cabinet thump is pretty incredible. In the rectifier mode especially this thing easily has tighter and just plain more bass response than the AD15 does at similar volumes. (I’ve a’b’ed them). Again these little 4" speakers are very efficient and voiced well.

Despite what I said about the lack of warmth and real amp dynamics, I find it’s noticeably less digital sounding than Line 6 amps up to and including the Flextones. The crunchy mid gain sounds on the Vox and twin are very smooth, and at times I feel it has more of a SansAmp type analog tone and feel than digital.

The tracking is very good, and touch response is the best in all digital I’ve tried so far. No lag or glitchy stuff going on in that respect.

The Tuner. Oh how nice it is to have a built in tuner. My old Boss tuner is MIA and I’ve been using a MIDI low e tuning note off a website I found for the past 5 or 6 months. This is much easier, and quicker. It seems pretty accurate, and although I have no need to even bother, I do believe you can calibrate it for some different tunings.

Most of all, modeller or not, this amp does a lot of very cool sounds that are reminiscent of a lot of very cool classic tones, and the amp is tremendously FUN to play. REALLY fun to play. Make no mistake, this won’t replace your tube amps, but for a home practice amp (or even a coffeehouse gig), this thing rocks and is really a heckuva lot of bang for the buck.

Hopefully I’ll figure out a way to do some clips.


Ok to did anyone make it to the end?? :clap::laugh2:
 
Re: A long drawn out amp review-

cool review!

-I've been thinking about grabbing a micro modelling amp to take out on the road as a practice amp. I'll check this one out...
 
Re: A long drawn out amp review-

Veddyy interesting.......

I've been looking for a practice rig ever since getting my Rivera. I could just plug my GT-8 into my SWR Strawberry Blonde like I used to, but not having to hook up so many cables and power supplies appeals to me. Basically it'd be guitar->Cube and I'm off and jamming.


I wonder how much I can beat GC up for one.
