The Looper on this is excellent. You can overdub yourself playing multiple times on a single track which is nice. You can also import/export your recordings as wav files to the SD card. The unit does not come with an SD card, which for the price, I think is kind of cheap on Line6's part. This unit has the same dry sounding Line6 effects that the POD units have. 36 User presets 12 Amp models, chorus, phase, reverb and a few other bells and whistles. Accessing various functions on this unit takes some getting use to. there are 3 buttons for the different functions then there is a wheel that you turn for controlling levels and finding drum kits and songs. The 4-way button is used to scroll through the menu options. I did not find it very intuitive and spent a while reading the manual before I got comfortable using it. Physically, the casing is pretty solid metal. The 4 foot buttons are solid but there is no obvious click to them when stepped on. The buttons and knobs are plastic so no telling how long they will last. The LCD screen is recessed and a definite dust and dirt trap. I have pretty much figured out how to use mine now for what I purchased it for which is the looping feature. As for the tones and amp models, I'm not a big Line6 fan so I would say they are average. I would not use this pedal live because I would be bending over all the time to adjust it and it wouldn't be worth it for me since I have other effects that I use. However for a practice tool, I think it is OK. A little over-priced and Line6 should include at least a 1GB SD card with the unit.

If you absolutely have to have a looper the Line 6 JM4 is the only one worth having. That being said, you should be aware of what you want to accomplish with this unit, whether it's improving your playing, songwriting, or just jamming to solidify your timing.While the unit is well-made, with the exception of some chrome plastic controls, it's use as a learning/practice tool is somewhat limited. Specifically, even though the 200+ songs and grooves are performed by A-list studio musicians, the range of music genres is so broad that you may only find a few loops/songs that suit your taste and ability. While you can change the key and tempo of pre-recorded material, you cannot change the progression, which will eventually become boring.The unit does include some common effects, but not the quality or depth you would get from other Line 6 units like the POD. You may be satisfied with these limited settings if you're just using the unit for practice.One of the nicest features of the unit is it's ability to import WAV files via it's SD card slot for jamming and working out breaks. You can record your performances and even overlay performances (sound on sound) and save the results. The manual says you can export what you've saved as a WAV file via the "Save Rec Mix As WAV To Card" but the unit I had always gave a write error when attempting to perform this task.Recordings are saved via a JAM proprietary file format. These files are not readable by your computer without a third-party conveter from the Line-6 bloggers.In summary, this unit may work for you if you're a beginner or to a lesser extent if you're a more advanced player. But if you need more variety in your practice, for about the same price I'd recommend visiting the Musician's Friend website and ordering a copy of "Band in a Box" and perhaps a small multi-track recorder to work out your songs and practice routine. The JM4 Looper tries to be a lot of things all at once and in the end does't accomplish much of anything very well.

Comments about Line 6 JM4 Looper Guitar Effects Pedal:

I didn't like it and sold it off. I did not like that it had a proprietary file system, JAM. It requires that you import other sound files in WAV format. No computer connectivity. Each loop must be stored as a song. the storage process needs a better user interface. The machine boots up in FX mode with amp modeling on(hated this). Each of the 100 factory installed demo songs uses it's own amp model. I like about 7 or 8 of the 100 installed songs or loops and hated all the amp models. The volume leveling for everything must be turned down to feedbackless manageable levels before you can even use it.

I think this product was developed by a focus group. If you want an FX processor get one, if you want a band in a box song manager get one that uses common file formats like mp3 and wav without conversion to another format, if you want a pedal that captures a snipette of playing for you to play over then get that too. That is the problem with this pedal it try's to do all three of those things and ends up doing neither very good.

For me the RC-30 is a better fit to capture a guitar rhythm and then play lead or sing a verse over it, it also has USB PC connectivity and does either loops or songs. I don't need an fx processor or amp modeling. I use a chorus and compresser with boost or distortion coming from channel 2 of a tube amp. I want to hear my tube amp.

With any cell phone and a 3.5 mm stereo jack can plug into a mixer to play loops or song backing tracks or even mp3 recordings to jam with. Does anyone need a pedal to play back music through a guitar amp? If you wanted to play back thru your amp wouldn't it be less costly to get a 3.5 mm to 1/4" jack converter?

        Comments about JM4 Looper Guitar Effects Pedal:

        What a great looper (and so much more). I am a beginner guitar player and this is a wonderful learning tool. A little spendy but in my opinion well worth the money. I am still learning to operate it properly and make use of all its functions. The learning curve is a little steep but not undoable. Learning the looper has been a fun experience as well. Don't take your significant other out to diner a couple of times and you can afford it. I'm sure he/she'll understand......maybe not.

        Comments about Line 6 JM4 Looper Guitar Effects Pedal:

        I've owned this looper for several years now and it still sounds amazing. It's been well over 5 years or more since I bought this unit. There were a few out at the time like Digitech jamMan and boss RC but these didn't have the capacities for storage or options I was expecting. The built in loops for both drums and instruments including the abilities to change keys, mute tracks, and modify tempo were really a nice features which I use for song writing and solos. The effects are fairly standard but work fine for my needs. There were additional features that put this looper ahead of the pack like, changing the pedal to an effects pedal, start, stop, and half speed functions to name a few. The display is larger and allows for naming your work which is nice to have when several hours of material are put onto you SD card for transfer to your PC. The lights for the unit are easy to see and the blinking light helps ensure I am following tempo. I have read a few reviews about noise but I've need experienced this issue. The only 2 complaints I have are no usb port and loading the wav file from SD to internal memory is slow. It's very large and uses a lot of power so it is not Ideal for a pedal boards. I solved the size and power by purchasing a Digitech JamMan Soloist XT and moving the loops to the Soloist XT which now all access to the loops from the pedalboard.

        Comments about Line 6 JM4 Looper Guitar Effects Pedal:

        The best sound quality I will get is directly through my Fender tube amp. The sound quality is significantly degraded by feeding through the jm4. Sampling the analog stream from the guitar, mixing it with digital tracks, and then feeding again to my analog tube amp degrades the overall sound quality. The ability to overdub your own tracks on the fly is really good and not hard to use, and a great way to experiment and compose. The ability to adjust the input level from your guitar to the level of the pre-recorded tracks to get the right mix takes constant tweaking. I think the amp effects are mediocre at best.

        Works great with a 3 piece band using rythem tracks , has the best realistic sound effects I've ever heard in my life more than you'll ever use I love them all. When playing stuff by Steely Dan , SRV even Beatles the tones are perfect . But I think the looper is more fun than all of it . It has the same brain as the spider jam , which I have and love it to, but this is so compact you along with the Min-ETunes no amps or extra guitars to pack around when playing one night stands bottom line it's a great piece of equipment thank you M/F for another great deal , keep it coming Line 6

        Comments about Line 6 JM4 Looper Guitar Effects Pedal:

        I was really excited to get this pedal only to be dissapointed. The lack of quality, engineering, and techinical support by Line 6 was dissapointing. I'll never buy another Line 6 product again
        Do not buy this loop pedal for any professional sounding tone.
        This pedal does a decent job looping my electric guitar. Makes my fender Deluxe sound like garbage when I try any different tone. The sound levels are all different for each tone. One will be dead quiet and you'll switch it to a new tone that will blast your ears. Line 6 should have spent more time on this pedal. The power supply died on me in less than a year and after two attempts of connecting to Line 6 in Europe for technical support to replace my supply (3 hours of waiting) they hung up on me. Not impressed with the pedal.
        Power supply quit in less than a year
        Not worth the money.
