Roland Jazz Chorus 40 Review


  • Decent build quality
  • Excellent tone and that wonderful true stereo chorus effect.


  • On the other hand; a fourth-footswitch socket to change the loop would be fine.


The Roland JC 40 is a 40-watt solid-state combination with just two 10-inch speakers. Rather than the classic two-channel Jazz Chorus layout, it provides just the chorus/effects channel using a bright switch, volume, treble, middle, bass, distortion, and Roland JC 40 reverb controls.

There is also a rotary switch for participating vibrato and guide chorus effects, which may be corrected with the front panel’s rate and depth knobs, in addition to a brand new fixed chorus impact manner.

Roland Jazz Chorus 40 Review Features

The front panel also contains stereo input, yet another brand new addition for linking stereo effects, combo amp modelers, or guitar synths into the combo amp and keeping accurate stereo operation.

The back panel is laden with features, providing a 1/4-inch headphone output, stereo line outputs, and impact loop using one (stereo TRS?) Send, set of stereo yields, and series/parallel change.

Personal 1/4-inch footswitch jacks are provided for engaging the jazz chorus guitar, reverb, and distortion multi effects individually with optional footswitches.

Rather than utilizing a spring reverb tank, the Roland JC-40 is outfitted with built-in electronic reverb to make its luscious reverb effect.

By Roland, the distortion and vibrato outcomes are recently developed for contemporary fashions.

However, lovers of this signature JC stereo chorus effect don’t have anything to dread as the Roland jc40 still keeps the same vibrant, lush, and three-dimensional personality. The one thing missing is that the sound is frequently encountered in older analog chorus circuits.

The JC-120 place a new benchmark for a clean tone on its debut in 1975, and also the JC-40 lives up to that reputation by providing only the most magnificent blank tone I have ever seen coming out of a sub-50-watt 2×10 combo.

Notes around the fretboard’s whole range of thickness, measurement, and chunks, the assault is instantaneous and invisibly, and the tone stays crystal clear with the volume control completely maxed.

The bright switch creates a slinky, razor-sharp treble that evokes the heyday of both disco-funk or Jamie West-Oram, along with the EQ section is elastic.

I have already raved about the stereo chorus multi-effects, which is entirely hypnotic; however, the reverb warrants similar compliments because it produces a broad impact that unites the best of the spring and electronic hall reverb without getting in the way of the dry signal’s definition and clarity.

The distortion effect, as always, is a love or hate affair. However, if you are a fan of contemporary solid-state distortion (a la Dimebag or Wayne Static), you will probably love it.

I preferred having a fresh boost overdrive rather, which kept all the JC-40’s fantastic clarity and articulation when providing added sonic punch, keep, and only a hint of crunch.

The JC-40 is a perfect platform for a new pedal or rack impacts rig, in addition to the most recent amp modelers, guitar synth, as well as acoustic-electric guitars.

Even when you’re a tube distortion purist, the combo amp is small enough to fit into almost any rig without sacrificing transparency or these sexy JC blank tones.

Feel And Seems

The JC-40’s stereo front desk inputs make it an ideal companion for gamers using multi-effects floorboards, with wide-range clarity, which will require a little tweaking if you would like to keep some heat on your sounds. We attempted the JC-40 with single-coil and humbucking guitars, each of which seemed equally striking.

The built-in vibration is slightly warmer and smoother than earlier versions, while the electronic reverb is smooth and broad, with a long tail.

The JC-40’s chorus effect outputs a dry signal to a single loudspeaker and a moist effect-only sign to another, developing a three-dimensional soundstage that soothes and soothes delightfully.

This is the center of the JC-40’s noise a more distinctive and one-of-a-kind chorus multi-effects that have been replicated several times through time, but it isn’t easy to imagine anyone besides Roland doing this well.

You can control the rate and thickness yourself with the Manual setting or select Roland’s best settings together with all the Fixed options.

The vibrato effect adds another classic dimension with a vast range of depth and speed that covers scenic, slow heartbeat impacts to full-on surf. The JC-40 is likewise quite pedal-friendly and seems excellent with a high-end overdrive pedal plugged into the input jack.

One central selling point is how compact and portable it’s: easily performed with one hand and small enough to match a single chair of an average family hatchback, it is perfect for smaller clubs, clinics, or rehearsals.

But it’s on the expensive side and faces stiff competition in several other mid-priced products with onboard effects. Still, not many are original stereo, and not one will have the JC-40’s signature 3D moist/dry chorus. Should you fancy plugging into a short history, look it over.


The Roland Jazz Chorus 40 is a sterile machine that delivers wonderfully three-dimensional noise by dividing the wet and dry signals between the two 10″ speakers.

The range of the vibrato and chorus controls can move between subtle warbles reminiscent of Mike Stern’s and John Scofield’s older records to twisted, psychedelic modulation once the result is maxed.

As you can hear from the clips about the internet version of this article, the distortion controller may not replace your preferred overdrive or low-gain distortion. We hope that our Roland JC-40 Jazz Chorus Review can help you know more about this amp.
