    you only need one amp, because it is stereo:

    "Now, there’s also a true stereo input for enhanced performance with stereo effects pedals, guitar synths, amp modeling gear, and multi-effects"

    If they've fixed the hum that plagues so many of the 120s I'm sold. I only ever use the JC setting on my cube and would love to have an amp without all the FX and crap on it.

    That was my exact response. And it wasn't just the 120's. I had the same hiss from about five different version of the JC's. I really like what this one offers though.

    A friend has the Roland JC-55. I always liked this small, powerful and very good sounding amp. Once I A/B my Cube 80XL and the JC-55 and have to say I could dial in pretty much the same tone on my Cube. Difference is the JC is open back the Cube closed back. So I stopped my search for a JC-55. Anyway, I'll check the JC-40 when it is available.

    In all seriousness, what would be cool is if there was an extension speaker out, and THAT was in stereo with the built in speakers.

    funny thing is I have a 90s or late 80s JC55 (two 8in speakers). Great amp.. but I cant get great jazz sounds out of it (but then again I cant get a good sound out of an AC30 either)

    Also as mentioned in other threads.. noisy chorus.. sounds great but noisy. A few people have mentioned that this is an amp that is very accurately modeled by a few other manufacturers

    Looks like it will be $600 MSRP, which is half the cost of a new JC-120. Does anyone else think that new JC-120s are overpriced? Yeah, you can always find a used one...

    There are always leftover Roland GA-112 and 212s around. You can get either for less than the JC-40 and it is 200W for the 212. The bad news is that both are heavy.

    Yeah it's a shame they didn't keep the same form factor but bump the wattage to 80 or 100 watts. My Cube 80gx is plenty loud for most gigs and has a line out. Seems more versatile than 40 watts. But comparing watts is never apples to apples. I'll have to try one of these out in store.

    Looks like there's just one channel so it's probably 40 watts, also it says that the distortion is updated. Probably digital effects in this one.

    Whenever I noodle with a JC in a music store, the first thing I do is make sure the distortion knob is turned all the way down.

    Hummm? It was the Hissss that bothered me most coming from my JC-120. A 40 watt SS would be pretty much a practice room amp, wouldn't it. Would be interesting to hear the latest iteration though.

    I had a JC-120, a new one- I had issues with headroom with that amp. It was loud, but the louder the amp was turned up the worse it sounded. It was as if it desperately needed a limiter to keep the peaks from clipping. The tone of the amp at low volumes was gorgeous though, and the chorus was incredible. I sold it because my mid 1980's Peavey Bandit 65 sounded far better at high volumes and was much smaller. I couldn't justify such a large amp that only sounded good at low/medium volumes. I do miss the amp though, it had a unique sound.

    I'm not sure with this JC-40 how 2x20w would hold up considering I had issues with the headroom of the JC-120. Occasionally I see a JC-160 pop up for sale. I would love to try one of those!

    I'd honestly like to try this. I liked the JC120 but the hiss was definitely there. Not as bad as some JC120's I've played on.

    If the hiss had been addressed.... At 35 lbs I'd give it a consideration.

    I actually used the distortion. I cracked it barely open to give it a gritty lo-fi sound but otherwise clean.

    I love the JC sound. Preferably I'd have a preamp/Head that I run through my tube poweramp head & cab. Have toyed with the idea of buying a used cube and remove the preamp section. Anyone done that?

    The small JC40 looks nice too. I am definitely interested.

    *Thump! Shhhhhhhhhhhhhhhhhhh.....*

    Any JC owner knows that sounds.

    As mentioned, I am interested in hearing this but there is a reason (several) that I gave up the JC120 in favor of the Cube.

    The Cube is quieter, lighter and has a slight roundness to its sound as opposed to the slightly stiffer sound of the JC120. The turn off for this 40w is it likely still has the hiss. The dual speakers probably put it in the loudness territory of my Cube 80x though.

    I do like that the one channel is the one I used and it is about the same weight as my Cube.

    My old JC setting:

    Channel 2
    Distortion slightly cracked open to add a slight lo-fi grit.
    Effects circuit engaged but set to absolute minimum so you couldn't really heart am effect but seemed to warm the tone a bit.

    Certainly JC-ish. Like any amp... people are always out to get 'their sound' out of it regardless of what others may say the amp was meant to do. I'd need a demo taken in a much quieter environment than NAMM (understandably noisy) and am certainly waiting to read a review that addresses whether or not the hiss is still there.

  27. #26

    +1 on the great clean sound of the old JC model with 2 tens. Forgive me, I forget which model number that was.
    +10 on the the problem with the weight. I got tired of lugging it to solo gigs (which is mainly what I've always done and do).
    +1000 on the hiss, that was the deal breaker. It drove me crazy. But then, I've mainly used dead-quiet amp set-ups and play in relatively quiet venues.

    But that clean. It sure had its own character... I too will watch for some real-user reviews of the new model.

    I saw on one of the NAMM videos it was said that they have redesigned the distortion circuit. Not sure what exactly that means... but I had actually found a nice use for it. I only care about whether or not they've done something about that HISS. haha.

    this prompted me to trot out the old jc77 and give it a whirl as i periodically do and those clips sound pretty much like mine. which is to say, sort of like ass, so i guess they nailed it. yay?

    honestly, it isn't bad, it just isn't for me. i never really liked it with electric guitars. acoustics, archtops, bass, e-drums, keyboards, vocals, and an ad hoc boom box, sure, but electric guitars? not so much. its usually fine. they sound a little stiff and sort of just... there. that comes though even in these demos. two dimensional may be the term i'm looking for. its better with solid bodies and effects, at least.

    and to nobody's surprise, i hate the reverb and chorus, too.

    Lots of jc120 owners here, personally have a JC 55. Bucking tradition, I find it better rock amp than for more traditional forms of jazz. The one 20th also abusively heavy, just a little shy of twin reverb territory. The chorus is great but noisy. Quite a few people have posted, but I have no personal experience, that some of the amp models in the newer Roland amps sound very similar, are quieter, and the enter a bit more flexible. The only thing that 90% of the owners agree on is that the distortion is painfully horrible.

  32. #31

    they re-did the front end on this new jc-40...the pre-amp is now in stereo...also they redesigned the distortion to be useful...something it never quite was on the jc-120...albeit it's got 2 10" speakers and is only 40 watts...so its not gonna be huge like the jc-120 can be..volume wise..tho size and weight wise is also applicable...hah

    i'm interested in checking it out

    i know lots of guys that love the old jc-120..real workhorse

    cheers

    The old Jazz Choruses were kind of famous for having a low-level persistent hiss which bothered a lot of people. I have a JC-77 which has this---too bad--if not for this, it would be a wonderful amp. I like the tone, both for jazz and blues/rock (I'm not a overdrive kind of guy.) Probably in a band setting, the hiss would not be noticeable...but for home use, it's not ideal. Some people say they take pedals well, but I've not tried, so have no opinion.

    Strangely, I have an old "orange cube" Roland which is quiet and sounds good...40 watts. For $75 it's a great little amp.

    Maybe the hiss has been done away with on the newer models...is that what you're looking at?

    The first hands on report I've seen said that it was much quieter than the old JC's. They seem to be just making it to the stores now which would explain the lack of buzz on the forum.

    i like my old jc77 as everything but a "jazz" guitar amp. just a tube guy, i suppose. i will note that it does sound great with acoustics and floaters, to my ear. i much prefer it for that than i do electrics or archtops with set in pickups. and as you'd expect, its a pretty good pedal platform, though it can be picky with drives. pretty sweet clean with lots of time based effects.

    haven't tried the new one, of course.

    I'm struggling to see how 40 watts ( or is it 2x20 watts?) will provide enough headroom to gig with, at least in a band with a drummer.

    I don't understand anything about how amps work, but I've seen buskers play outdoors through a Roland Street Cube, being heard at a distance; and that's a 2.5W+2.5W amp! The Street Cube is a digital amp, however, but I don't know if that makes any difference.

    I love the JC clean, and am hoping the JC-40 doesn't hiss like its big brother, because I'd be using it mainly at home.

    When Roland introduced the JC amps in the 70s, motion on a guitar signal...chorus ...was popular (Scofield, Stern, Metheny, Hall, etc.). I used the 120 back then for rock and jazz and liked it a lot. Bet the new 40 is good. No hands on experience though

    Their unpopular GA-212 had 200W. They could have done a lot more than 40, here. I think they didn't want to muscle into JC-120 territory.

    Thank you all for your replies.

    I just always want a new toy, and besides, two speakers look good.
    A little creative wiring and you've got a $600 extension cabinet.

    Here's another 'creative' rationale: using this as one of a pair of different amps,
    like one with tubes; not much discussed here and probably for good reason, but I'm in the dark.

    It's a true stereo amp both input and output and even in mono, the 2x10 setup will sound very different than a one speaker amp. It has a place.

    I had a JC-60 for about 20 years. Like half of a JC-120, but with just one speaker. I think the chorus was a bit sweeter on the JC-120 because of the two speaker spread. Roland was wise to get two speakers into the JC-40, imho.

    And yes, mine had a permanent low level hiss...but holy moly the clean sound was just super squeaky bright and clean. Good for mimicking everyone from Adrian Belew to Pat Metheny to Terje Rypdal. In fact, it always made me imagine icy nordic fjords! Quite lovely, very upfront and present--but not at all a "warm" sound, imho.

    It was pretty dang heavy for solid state amp of that size, or so it seemed to me.

    I ran a DOD analog echo, and an early ProCo RAT distortion pedal in front of it to dirty it up for rock.

    What is it with the Roland hiss. I've got a Cube 60 that sounds excellent but there is this constant hiss even when the volume is at 0 even with nothing plugged in. Amp is good for live applications with playing with others but not in a solo setting playing sparse passages or for recoding.

    That's weird. I have one of the first gen digital Cube 30s and it's really quiet. No notable hiss really unless you turn the volume and gain to 10. In Australia these sold with a 3 prong plug which may have something to do with it -- I know in some countries they came with a two prong. I'm a Mesa Boogie guy and you should hear those things on the gain channels -- it's like frying eggs (no it's not the preamp tubes just the nature of cascading preamp gain designs); but it's not noticeable once a drummer in a band situation starts hitting his/her cymbals. You just don't hear the hiss anymore; and your mind focuses on what guitar does best -- the midrange.

    MOSFETs = Hisssssssss. MOSFETs sound like tubes/valves; that's the reason why.

    No, I don't know why the Roland JCs hiss. MOSFET-hiss was something that was bandied about in audiophile circles back in the day. So, over time, a myth grew that MOSFET = Hiss.

    As for herssss, that's hiss with more bass energy. Like pink noise. Pink noise. Hersss. Geddit?
