OVERVIEW

Legendary stereo tone and modern innovation for one killer combo amp

The JC-40 Jazz Chorus delivers Roland' renowned "JC clean" tone and signature stereo chorus effect in a compact combo amp with evolved features for the modern guitarist. Like the flagship JC-120 amp that it's based on, the JC-40 offers a classic stereo clean sound that' a perfect palette for tone shaping with stompbox effects. Now, there's also a true stereo input for enhanced performance with stereo effects pedals, guitar synths, amp modeling gear, and multi-effects. In addition, the JC-40's onboard effects include newly added features and updated sounds to support the needs of today' players.

JC Clean: The Benchmark in Clean Guitar Tone
For 40 years, players around the world have revered the iconic clean voice and huge stereo sound of the JC-120 Jazz Chorus amplifier. With the JC-40, you can now enjoy the genuine industry-standard tone in a scaled-down amp with innovative modern refinements. Two independent power amps and custom-designed 10" speakers deliver punchy stereo sound that won't get buried in the band, while durable, road-tough construction ensures years of reliable operation on stage and in the studio.

Famous Stereo Chorus and Other Effects
Beyond its stellar clean tone, the JC-40 includes onboard effects, all newly refreshed for enhanced performance. The trademark Dimensional Space Chorus stereo effect fills the stage with immersive 3D sound, and now offers selectable fixed or manual modes for increased tonal range. Renewed vibrato and reverb effects are on hand, and both operate in stereo for rich, deep performance. There's built-in distortion as well, updated with a smooth, satisfying tone that' great for all types of music.

Stereo Input for Multi-Effects, Modelers, and Synths
With its front-panel stereo input, the JC-40 allows players who use stereo effects devices to achieve wide, inspiring sound without having to carry around two separate amps. The amp' rich clean tone lets you get the most out of external stereo pedals like delays, reverbs, and various modulation effects. It' also perfectly suited for advanced gear that employs amp modeling, multi-effects, and/or synth capabilities, such as the GT-100, GP-10, and ME-80 from BOSS and GR-55 guitar synth from Roland.

Ideal for Pedal-Based Players
If you create your sound with stompbox pedals, there' no better platform than the classic JC clean amp. The rich, neutral sound won™t color your basic guitar tone, perfect for hearing exactly what your pedals put out.

Get Connected
The JC-40' rear panel is filled with connectivity options. There's an effects loop for patching in mono or stereo effects, and you even have your choice of serial or parallel operation. Line Out jacks give you a convenient mono or stereo feed to a mixing board or recorder, while the headphones jack is great for quiet practicing with your setup late at night or on the road. There's also support for optional footswitches, allowing you to easily turn the JC-40's chorus/vibrato, reverb, and distortion effects on/off while performing.

Finally, I can get the JC-120 sound without getting a hernia. It may be light weight, but the sound quality is no lightweight. A little pricey as it is a new product and no one seems to want to discount it yet, but once you hear this amp the price is a true value. No buyers remorse on this purchase. Only had it for 2 days, and I haven't yet tested all of the features because I immediately got the JC-120 sounds I like by tuning the dials to familiar settings. Put the volume low or high and the richness stays constant. It would be nice if the footswitch was included at the price. The distortion is better on the JC-40 than on the JC-120. Use your favorite distortion pedal instead, it will sound great through this amp. Well done Roland, but please include the footswitch.

I purchased this amp to be my primary portable 'sit in' amp, something that sounds full but can be setup in one trip, and with little effort. I was not disappointed there, the amp is very lite and a sounds really full.

After playing it a while, I noticed a few issues. Turned up past 6, it tends to rattle, more so if the distortion was turned up, so if you are playing with a moderate to loud drummer, it has it's limitations (as I expect from a 40watt amp, but not to the extent this amp did). It sounds like the rattle is coming from the chassis, not the speaker, and things are riveted so it is not as simple as tightening something up. Also there is no dialing in the distortion level, it is either on or off, also, unlike a tube amp, it does not behave the same by rolling back the volume on your guitar, so not being able to dial in low amounts of distortion, or finding that sweet spot at varying volume levels using the the amp's distortion knob, is a big drawback for this solid state amp (or any amp). The amp is very bright.

Solutions: I was able to overcome most of the issues above by replacing the speakers and using a tube pedal. The tube pedal is great, it uses a 12axt and I have it turned way up to 10 and distortion to 2, now it behaves more like a tube amp with the guitar volume. I tried a tube screamer, maxon, rat, etc.., but a pedal with an actual tube in it did the trick. I don't use the amps distortion. Also replace the speakers with Eminence GA-10s, it sounds much better with distortion/overdrive now and better overall. After the upgrades, I should have gone with Fender's 2x10s vibrolux, but it is not a stereo amp and does not have the Roland spatial effects, so always a trade off. If a company makes a small stereo tube combo amp, I think they would have a great selling amp. Roland needs to make a El84 version of this amp, or at least have a tube preamp section for both clean and distortion channels.

    Comments about Roland JC-40 40W 2x10 Jazz Chorus Guitar Combo Amp:

    The JC-40 is one of the best amps I have ever owned. The distortion, reverb and chorus are perfect and provide a great stereo sound. This is the warm sound that makes playing jazz a real pleasure -- but just as good playing blues.

      Comments about Roland JC-40 40W 2x10 Jazz Chorus Guitar Combo Amp:

      After using it on 3 gigs, I was surprised how loud the amp was on 2 or 2.5.
      The gigs were not loud rock gigs with a hard hitting drummer, but soft to medium level. How much more volume you would hear on 4 or 5, haven't needed to go there yet, so I don't know.
      Although it's great that the amp has stereo inputs, the speakers are still pretty close together, so it's not a dramatic effect to the player or the audience, but nice just the same.
      You do lose a little volume with the internal chorus on.
      The hiss that JC amps are infamous for, I don't hear it on this amp.
      Digital reverb sounds good to me. I played both a vintage BK Butler Chandler Tube Overdrive and a Boss OD-1X overdrive and other pedals thru the front end of the amp with good results.
      Overall, a very nice solid state amp. I also own a Quilter Aviator, and a Mesa Boogie Mark 5 25.
      All three amps sound good and are gig worthy.

        Will use this on low to medium volume gigs.
        Have some stereo effect pedals, and you can hear the stereo effect, although the audience won't probably notice.
        Built in chorus sounds great.

          Comments about Roland JC-40 40W 2x10 Jazz Chorus Guitar Combo Amp:

          The amp is a good standard platform if you will for whatever kind of music I'm playing. I'm not a jazzer per se, but I wanted an amp that could go in whatever direction I wanted to go. It's great with effects and has a good clean sound. The on board chorus is excellent. The reverb and distortion are ok, again depending on what you want to use the amp for. Yeah, you'll probably get more mileage from a tube amp, but for the price the JC is worthwhile. My only issue is it can be noisy. Fair warning; the JC is a totally true reflection of you guitar. If your pick-ups are run of the mill you will get humming or buzzing. Effects will cover this, but the JC is true to it's jazz name. I don't think this amp is for everybody, but did I mention that it's very very LOUD!

          Comments about Roland JC-40 40W 2x10 Jazz Chorus Guitar Combo Amp:

          Best amp i have ever owned. Cant imagine that there is a better solid-state, practice-sized amp. Let me start by saying i had not ever played a JC120 before this. I went out on a limb and took a chance on this amp based on the videos and positive reviews of the Roland Jazz chorus line of amps. The amp arrived. I plugged it in and turned it on. Right away i noticed a click and steady hiss as the amp powered on. This hiss volume increases as you increase the volume of the amp. I was troubled initially but when i plugged in my guitar and realized how incredibly loud this thing gets(when playing by yourself you only need to barely have the volume knob turned, very loud amp for 40 watts) i realized it wasnt even really noticeable. As long as you are playing the guitar you will not hear this. However i was still quite put off by this and thought there might be some sort of electrical/wiring issues. I did a little investigating online (forums, reviews, etc.)and quickly discovered that this is a trademark (perhaps a negative one) of the JCs. Turns out many experienced JC players and enthusiasts have NEVER played a Roland JC that DIDNT have this hiss. Just wanted to say this to warn those who are considering this amp without ever having played one. Not a problem i dont even notice it anymore. However i could see it bothering some people. I'd think a noise gate pedal could probably clean it up a bit if really bothered you. Only other negatives to this amp are the onboard distortion and reverb. Distortion sounds kinda cheesey like an orange boss distortion pedal but less powerful. Sort of universally agreed that the distortion sucks on JC's. Reverb is a digital spring reverb but doesnt sound very good to me. others think it is great though so just my opinion. Other than that its best clean tone money can buy and best chorus money can buy. And it is made for effects! Invest in some pedals and bring out the tones that you didnt think you could ever make! Blissful sounds!

          Most articulate clean sound I have ever heard. Amazing tone. Fabulous chorus and the reverb is pretty good too! Even the distortion is usable, right in that sweet spot of a blues breaker tone. Much louder than I expected. A must have for anyone doing recording!

            You simply can't beat this amp for the price range. Beautiful cleans, that're even better than the JC 120 cleans, honestly. Light weight, for a 40w solid state amp. Easily could over power a drummer. I was skeptical about the power range, but it plays over a loud drummer, easily. Plenty of head room, great for effects, and pedals. I would strongly advocate this amp.

              Comments about Roland JC-40 40W 2x10 Jazz Chorus Guitar Combo Amp:

              Had a JC120 in high school and it was an incredible amp, but sold it for whatever reason. Since have been using a wide assortment of amps and now own a Marshall, Vox, Blackstar, Tube Works (great cheap 4x10 amp), and a couple others, but the JC 40 is my new go to amp. Forget what you've heard about tube amps, you want a warm sound, try a JC40! If you need more gain, the onboard distortion is much improved over the useless distortion on the 120, and is very adjustable with a distinct sound ... For heavier tube-like distortion, a Pro Co Rat is the best I've found for use with the JC series.
              And don't forget the chorus! It is the smoothest, and most useable chorus imaginable, and the JC 40 has vibrato, manual, and fixed modes, so you will never need an outboard chorus pedal (if you do, have your ears checked). No other amp picks up nuances in playing like a JC, and although its called a Jazz Chorus, any guitarist will be thrilled with the sound and versatility of this amp. And the best part is that it's very portable yet loud enough for most venues, and at the price, its really a steal.
              And any studio owner needs to invest in a JC40 for sessions because you will spend hours trying to dial in your old tube amps and pedals to get the sound you get the 1st time you turn on the JC40.
              I've never played anything in stereo with the JC series, but I've heard that this can give an entire new dimension to one's live and recorded playing.
