Take your playing to new heights
Combining exhilarating jam tracks with sound-on-sound looping and a full arsenal of legendary Line 6 tones, JM4 Looper sparks inspiration in ways other looping pedals can only dream.
JM4 Looper features over 100 Endless Jam tracks and drum grooves in more than 10 styles performed by top LA and Nashville session players. These tracks aren’t rigid and robotic; these are actual recordings laid down by A-list drummers, bass players, and guitarists. The real-world chemistry from these dynamic rhythm sections is here for you to explore your creativity in writing songs, trying out solo ideas or just honing your chops between gigs.
With up to 24 minutes of recording time, and storage for up to 100 recorded jams, JM4 Looper lets you capture all your riffs and musical ideas. A 2-GB SD card in the SD card slot provides additional jam storage and WAV file transfer to your computer or recording software. Plus, use the SD card to import your own songs into JM4 Looper and transpose, time-stretch or loop over any music you want.
The looper has dedicated footswitches for Record/Overdub, Play/Stop, Half Speed and Undo for super-easy practicing, songwriting and creation of an entire backing band on the fly. Layer guitar tracks, bass tracks, keyboards—even vocals with the balanced XLR microphone input.
Complete with a comprehensive collection of brilliant modern and historic guitar tones, JM4 Looper gives you access to 200+ artist-created presets, 150+ song-based presets, 12 Line 6 amp models and a stunning array of effects for guitar and vocals. There’s even room for 36 presets of your own creation.
A complete palette of colors of textures
Add depth, color and texture to your guitar tones and vocals with any of the pro effects included in JM4 Looper. Spend more time playing and less time tweaking your guitar tone with Smart Control FX. Find the effect you want, turn the knob to the desired intensity and you’re done. Seven effects to choose from—use up to three at a time.
- Delay (with Tap Tempo)
- Tape Echo (with Tap Tempo)
- Sweep Echo (with Tap Tempo)
The sonic spectrum from clean to insane
JM4 Looper offers an extensive collection of modern and historic guitar tones including 200+ artist-created presets, 150+ song-based presets, 12 Line 6 original amp models and a stunning collection of effects for guitar and vocals. There’s even room for 36 presets of your own creation.
Just like most of us, each Line 6 original amp model has a light side and a dark side. Or, in some cases, a dark side and darker side…Red
Crisp, shimmering clean tones and warm jazz tones.
Classic, glassy high-end with some snap and bite. Inspired by a Fender blackface '65 Twin Reverb and a blackface '64 Deluxe Reverb.
From gritty, swampy clean tones to syrupy smooth drive tones. Inspired by a mix of a '65 Marshall JTM-45, a '58 Fender Bassman, a '63 Fender Vibroverb and a Supro.
Classic crunchy tone popularized by many early metal bands. Inspired by a '68 Marshall Plexi 50-watt
Tight and punchy high-gain sound. Inspired by a Mesa/Boogie Dual Rectifier
Famed and feared bone-crushing, brain-piercing grind. Inspired by the Mesa/Boogie Dual Rectifier red channel
Glassy clean tones like those from the late 60s/early 70s. Inspired by a ‘73 Hiwatt Custom 100.
Swingin' rockabilly tone a la vintage tweed. Inspired by a '53 Fender tweed Deluxe Reverb, a '58 Fender tweed Bassman and a '60 Gibson Explorer
Early British rock tone made famous by the Beatles the Stones. Inspired by a fawn Vox AC-30 with an updated and expanded tone control circuit
The infamous brown sound inspired by a ‘68 Marshall Plexi 100-watt with a few added extras: jumped input channels and a Variac transformer
Aggressive high-gain sound. The mid knob sweeps the tone spectrum: set to minimum for fuzz-pedal characteristics; set to noon for creamy, modern high-gain; crank it for Class A carnage
Short of a complete meltdown, as much input-gain distortion as possible while retaining tonal definition and character

Line 6 Limited Warranty
Please be aware that your warranty is only valid in the region where you purchased your unit. For instance, if you buy your unit in Germany, then you must have the unit serviced in Germany, or within that region. If you live in South America, you will be interacting with the distributor for the country that you live in. It is for this reason that Line 6 recommends that you always buy your unit locally.
You will need to present your original, dated proof of purchase to have any warranty work performed at any Line 6 Authorized Service Center for repair.

Helix Extended Warranty
Customers who purchased a Helix Floor, Helix Rack, or Helix LT processor, or a Helix Control pedal in the United States and have a copy of the original purchase receipt qualify for the extended warranty. Customers who qualify will have a second year added to their current one-year Helix Warranty at no cost upon registration.
Registration is required within one year of the purchase date. You already qualify if you've registered your Helix and have a copy of the original purchase receipt. Otherwise, register your product at the Line 6 website and make sure you have a copy of the original purchase receipt.
Line 6 warranties transfer from one end user to another within the original warranty period (as long as the user has the original dated proof of purchase), but not when purchased second hand from a retail outlet.
If you purchase a Line 6 product sold as new from an authorized Line 6 retailer with an online storefront, the standard warranty applies as if it were purchased in a physical store. If you purchase a used unit from an individual on eBay, you do so at your own risk with no warranty offered by Line 6, unless the seller includes a copy of the original receipt to transfer the warranty to you.
The only way to redeem warranty on a used item is to have the original purchase receipt, dated within the product warranty period. So if you fail to get such a receipt, the manufacturers warranty will not be honored.
The Warranty does not cover:
- Damage from physical abuse such as dropping the unit, impact from hard objects or damage to external components as a result of negligence.
- Damage due to liquid contamination.
- Damage resulting from any use other than that it was intended for.
- Any unit that has been repaired or had an attempted repair made to it by unauthorized personnel.
- Damage due to incorrect connection, connection to faulty equipment or connection to faulty or incorrect power supplies.
- Damage in transit as a result of inadequate packaging or protection.
