      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:

      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.

      Comments about Line 6 JM4 Looper Guitar Effects Pedal:

      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

      Save your money. This thing sounds terrible. And for audio equipment- I'm pretty sure that's all that matters. I have tried for months to get this thing to sound better but there is so much noise I wouldn't even attempt to use this thing live.

      Half Engineered

      By Joshua Burke

      from Undisclosed

      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.

      This device has pretty much the same features as the Line 6 Spider JAM Amp. The only differences is that it just have the foot switches but does not have an on and off switch for power. It would have been better if this device had a different set of Tones and Songs loaded than that of the Spider JAM Amp in order that the user could combine the two and have more Tones and Songs to
      select from. If you don't own the Line 6 Spider JAM Amp this device is very nice to have.

      I don't know...

      By Sebforget

      from Calumet Island, Qc

      Comments about Line 6 JM4 Looper Guitar Effects Pedal:

      I don`t know about this thing. First of all, I bought the JM4 for acoustic live shows to add rhythm tracks and percussive sounds. I?ve given up on this for now because I can?t get anything to work right, however I admit to being a newbie on acoustic live set-ups. But trying to get the JM4 to work without using the amp modeler is a hassle and since I own the amps I would use using the JM4 modeler is a step backwards. If you don`t have the money and you enjoy using lots of different sounds Line6 products are a great idea, otherwise the modeling simply sounds weak. The effects are insanely over the top, I can only use them on the 0 or 1 bar out of about 50 and the effect is still too pronounced! Unless you?re trying to mask bad playing with them the effects are useless ;).On the positive side and although I?m disappointed with the live applications I have discovered that I love using the JM4 for practice. I?m glad to see that Line6 added recordings from a variety of styles, for those who like to broaden their horizon. It is true you don?t get much selection from a specific style of music but since you can change the pitch and speed of the song you can make it sound new and you can always record your own with a drum track. It?s hard to get a band to accompany you every day and repeat the same repetitive patterns while you practice your chops and I always found that using recordings is limited. With the JM4 I can start, stop, loop and record all with my feet. I also use the JM4 to record new material when brainstorming ideas. I found that the JM4 is the easiest way to practice and record ideas. All you need is the JM4 a guitar and some headphones. I don?t think I?ll ever use the JM4 live, but has a practice tool it?s easy to use and has really improved my playing.

      Looper

      By Anonymous

      from Undisclosed

      Comments about Line 6 JM4 Looper Guitar Effects Pedal:

      When I received my Line 6 JM4 Looper it did not work. No sound out of it and would not receive my guitar. I was also disappointed because it looked used. The unit has some small scratches on it and the record button looked ruff like it had been pushed many times with a shoe. also the box looked suspicious. The corners of the box were damaged and torn. I was going to return the product even if it worked due to this.I returned the product and to my surprise it was on back order. I had to now wait a few more weeks to get it. The good thing is when it finally arrived it looked brand new and the box was perfect and new looking. Now my Line 6 JM4 Looper works great and it is a great product.

      Best Piece of Equipment for the Hobbyist

      By TBay Blues

      from St Petersburg

      Comments about Line 6 JM4 Looper Guitar Effects Pedal:

      This is a great piece of equipment for those that don't play with a band regularly or are trying to beef up there improvisation skills. It is in fact easy to use and intuitive while at the same time gives the impression of being very solid and durable. The drum tracks are much better than those found on some "mini-studios" and the backing tracks are fun and variable enough to not get bored. The presence of the SD card slot allows you to bring in songs and backing tracks from elsewhere so your jamming options are limitless. The looper is excellent, easy to use and with the additional memory associated with the SD card you can record and layer tracks until your heart is content. An aux input allows you to mic it up as well. For those that want to jam without worrying about noise issues- the headphone jack lets you do so worry free. The amp voicings and effects sound decent through headphones but sound surprisingly good in front of a good amp. For all of the tone junkies, like everything you have to play with the settings to dial in your ideal sound. Overall this is a great piece of equipment that will bring whole new life and creativity into your practice sessions and perhaps expose you to new sounds that would otherwise require many amps and many pedals. Probably not the best looper for gigging given all of the functions and digital effects, but great for practice and jam sessions. One minor complaint: why isn't there an on/off switch?
