80s/90s Rock and Metal Amp. The JC-40!
That's what our band plays and this amp does it perfectly without any pedals. It replaced my 71 Princeton and Fender Blues Deluxe. The definition and clarity is stunning. My bandmates were just as surprised. I run the distortion at 3 o'clock against a medium drummer, bass, and another guitar. Amp is still purring kitten quiet. STP, Judas Priest, Soundgarden, Black Sabbath RATM, Zeppelin, Helmet, Pantera, it covers them all. And the chorus does Plush so well.
Tone controls are very powerful and probably trip up some folks not very experienced with tone controls. I attached a photo of my settings. This is at band practice, and the amp sounds perfect.
Lastly, I plugged the old Princeton into the line out jack on the back of the JC-40 and it sounds like a rock concert. The clarity is just mind blowing. I think the distortion circuit is similar, if not exactly, to the Boss DS-1X Distortion Pedal.

Perfect pedal platform
Without turning up the distortion, vibrato, and reverb, this amp is perfectly clean. I love that it is a stereo amp as well. I play my guitars through a multi effects pedal, and I love being able to hear the stereo effects. I wanted the JC-120, but the price was prohibitive. This is the next best thing. I assume it can get loud. I never put the volune above 1. I can adjust the volume through my guitar and pedal. Except for the guitar, which is on 10, the pedal is on 1 as well. In other words, there is a lot of room for more volume. Great amp!! Thanks for all your help, Kyle!!

Spectacular amp and I'm not exaggerating one bit
Let me start by saying that I actually bought two Jazz Chorus amps, this one and the smaller one, the JC-22. While the JC-22 had a VERY nice and balanced sound/features for its size. It was severely lacking in bigger volume and low end response, I literally had the volume knob on it maxed out in my bedroom and it was barely that loud to be honest. If money grew on trees I definitely would have kept both amps, but I did ultimately end up sending the JC-22 back and keeping the JC-40 instead.

Now as for the JC-40:

This is a REALLY good amp for the money. I have owned many solid-state and tube amps over my 18 years of playing and this is definitely in the Top 3 amps I've ever owned, and it's DEFINITELY the best solid-state amp I've ever owned specifically.

The tone knobs are responsive, the reverb is very good which surprised me because most built in reverbs on solid state amps are very underwhelming sounding. The modulation dials are also outstanding.

This amp is honestly very good if you are trying to play anything from indie rock to prog/psychedelic stuff. I would not use this as a traditional blues or hard rock amp unless you are going to use a good overdrive pedal, preferably something with a warm sound to counteract the fact that this is a very bright sounding amp by nature. Would this amp keep up with a drummer in general though? Definitely.

For what this amp is I would give it a 10/10. It's pretty incredible and fun to play for hours.

Amazing Amp!
I just got my JC-40. I am very pleased and can't wait to strut this baby in front of my band mates. They will be sooooo jealous! The clarity is pristine and even without the "Bright" button punched in the sound jumps out at you. I am playing Ovation 6 and 12 strings through mine. This is definitely some of the best money I have spent on musical equipment. I might buy another one. You can never have enough backup! Thanks Drew.

Boss JC40
I'm going buy the Boss JC120 after I pay my recent gear off why you might ask because the Boss JC40 sounds so good.

What Do Our In-house Gear Experts Think?
Matthew Klopfenstein
I dabble in many guitar styles from surf rock to shoegaze, and this combo amp allows me to explore all of those styles with one easy-to-use box. The built-in chorus, vibrato, distortion, and reverb along with the clean and lush stereo tone of this amp inspire my creative desire every time that I plug in and play.

Simply put, modern electronic music wouldn't exist without Roland. Many of the electronic musicians here at Sweetwater cut our teeth on TR Rhythm machines and fondly remember programming our first TB-303s. We owe a good part of our careers to this amazing and innovative company. It's been fun to watch and grow right alongside Roland, as they've introduced wave after wave of revolutionary keyboards, digital pianos, and more. For example, Roland's V-Drum Kits continuously redefine the possibilities of electronic drums, beginning with SuperNATURAL technology to the latest Prismatic Sound Modeling. We're huge fans, and we'd love to tell you all about them. Whether you want a pocket-sized synth or a cutting-edge video mixer, if Roland makes it, then Sweetwater is 100% behind it.
