The Boss eBand ushers in the ultimate musical companion for guitarists who love jamming with their favorite songs. This portable all-in-one audio player is packed with big features: WAV and MP3 files can be loaded and played by Boss eBand, and the tempo and pitch can be changed. Plug in your guitar and jam along using the music player's powerful onboard COSM preamp and Boss effects. You can minimize the prerecorded vocals or guitar parts with the Center Cancel feature for minus-one play, and record and save your jams. There's even a sound library of backing tracks and rhythms onboard, plus a built-in tuner and metronome.

Boss onboard effects
The Boss eBand is loaded with high-quality Boss effects, including over 100 powerful guitar sounds that span a variety of genres. The Boss eBand also features the COSM preamp. Using eBand's Guitar/Mic input, you can apply the internal processing to your guitar or voice.

EZ TONE Sound Wizard
Creating your own sounds is simple with Boss eBand. The EZ TONE feature provides a quick, intuitive approach to tone creation based on graphic icons and a Tone Grid. You'll be programming at the speed of sound.

Memory-Card Compatibility
SDHC memory cards of up to 32GB can be plugged into the Boss eBand, letting you store thousands of WAV/MP3-format songs per card. eBand also lets you play WAV/MP3 files directly from USB memory stick, expanding your data storage and file-management options. (eBand comes with a 1GB SD card)

Convenient Phrase Trainer
Phrase Trainer is a feature packed function convenient for practicing phrases from imported songs. Phrase Trainer includes functions to control pitch and tempo of imported songs, Center Cancel for minimizing the guitar or vocal parts from prerecorded audio, and AB repeat. Now you can learn phrases without feeling any stress.

USB Audio Interface
The eBand audio player can be used as a USB audio interface, allowing the audio signals from eBand (audio-player sound + live guitar/vocal sound) to be transferred to PC via USB. As a result, Boss eBand audio can be recorded into DAW software on your PC. Furthermore, audio from PC can be played back on eBand. This means eBand can function as USB speakers for your PC.

Cool Extras
There are many other notable features packed into Boss eBand, including an internal recorder for capturing your guitar performances as you play along with songs or backing tracks. And speaking of backing tracks, 300 audio-loop phrases are onboard for jam-along inspiration. Of course eBand is also equipped with the essential built-in tuner and metronome.

Nice Product!!

By Heath

from Centreville, Va

Comments about Boss eBand JS-8 Audio Player with Guitar Multi Effects:

Just received my JS-8 in the mail yesterday from GC. There are not many reviews on this, so I thought I would send out my first impression after playing with it for a few hours last night. I loaded up a USB thumb drive with about a 1000 MP3�ۡ���s (varied bitrates), plugged it in the back and turned on the JS-8. I used a nice set of headphones and an Epiphone Les Paul. It was late so I could not check out the speakers. Tuner and metronome work great. I played along with a few MP3�ۡ���s: Center channel/guitar cancel has 3 modes (low, med, high frequency) and was effective in removing all vocals and most lead guitar. The modes allow you to adjust what is heard. The song speed adjustment would bring it down to 50% of normal speed, but had some graininess (the resolution of the sound would break up) to it. I even tried a 320 kbps MP3. The backing tracks included would perform in the same manner. The A/B loop worked fine. The preset guitar effects sound incredible and cover a lot of genres. I was also able to tweak all of the effects within each preset. They really sound awesome as is though. The backings tracks covered a lot of genres/Keys and sound very professional. They would loop seamlessly and go on forever, which is a big plus for practicing and jamming. -The menus were easy to navigate -Screen size and details I liked - Did not try to record or edit/save anything Bottom line: It�ۡ���s a great trainer, jamming buddy, and is made well.

Comments about Boss eBand JS-8 Audio Player with Guitar Multi Effects:

Oh my GOD!!! This is a big deal I dont get excited about many things but I just got my Boss E Band. I turned it on and listened to the demo then I plugged in a guitar and two hours later I still had not went through all the jam tracks. I've had a Fender GDEC that thing is a toy compared to the Boss E Band. The tones you can get are incredable want to play some blues you will have to stop your self you can go on for ever. I love this and its the best piece of music equipment that I own. I have a room full of guitars and amps but not even my Les Paul can touch this. I think every guitarist should have one of these to jam with. You better save up some money, sell a guitar or two and buy this it really sounds like a band playing with you. The speakers sound great its stereo but its not a 30 watt amp so plug it in to something big if you want to have it as loud as an amp. I have mine run into my mixer and it really sounds great. Its so easy to use I havent even opened up the manuel yet it's so easy even a cave man could use it.

Nice Piece of Gear

By Sean

from Boise Idaho

Comments about Boss eBand JS-8 Audio Player with Guitar Multi Effects:

The eBand is a great thing for what it does. This is NOT an amplifier. Its small, like the size of a toaster and nicely designed. Sits on my end table so i can noodle around while watching TV. It offers an amazing amount of varied tones and settings (100's) and all of those are able to be custom set to your wishes. The drum loops and backing tracks are great and plentiful, the slow down is great for helping me learn. It also has USB interface for direct connection to Garageband to give you even more options. Also saves to a Gig Stick or Photo SD Card. Attention Parents...., this is NOT loud..sounds like an ipod dock (BTW an iPod connects directly to this) its stereo and has nice sound. To get volume you need to connect it to either a stereo or set of powered speakers. Its the perfect thing for a college kid. Only minor issue is a little bit of buzz on the bass end, i think the speakers are just too small for some of the settings. External speakers solve this. BTW, GC guys in Boise are polite and helpful. I"m an old guy and I go there and feel really comfortable, not like some dinosaur in a museum...Thank you.

E-Band rocks!

By Tony

from Wichita, Ks

Comments about Boss eBand JS-8 Audio Player with Guitar Multi Effects:

I really enjoy the features in this unit, the COSM effects are second to none! The backing tracks are superior to the Line 6 JM-4 but the looper is not as good. My only dissappointment is that you cannot register the product on-line, probably because it's so new. In short this thing is loads of fun & provides hour of entertainment.

Great learning tool!

By Russ McPherson

from Edmond, OK

Comments about Boss eBand JS-8 Audio Player with Guitar Multi Effects:

The eBand has been a fantastic tool to help motivate me to learn and practice my scales. While this machine does a lot more, I mainly use it play along with the fantastic rythym loops. Each loop tells you what key is playing, making it much easier for a budding guitarist to quickly play a lead role in tune to the rythym. The simplicity and convienience of this thing is outstanding. Decent sound out of the small speakers too. Bass notes crack a bit at higher volumes, but this wasn't supposed to replace my Marshall... Highly recommend this product!

It Made Me Cry

By marcifer

from cottage grove, mn

Comments about Boss eBand JS-8 Audio Player with Guitar Multi Effects:

Amazing player with really decent effects. (Make sure that you back-up the memory card that is included before you format it, otherwise you will lose songs, rhytm data, USB rivers, and song list editor.) It's costly, but worth every penny, espeically with the speakers. The list of top-notch effects is impressive and includes a big variety of song tracks (rock, blues, pop, metal, funk, country, punk, etc.). The menu is easy to get used to, but the manual is big enough to choke a mule. It's about as loud as a portable radio, but has audio outputs too. The included AC adapter has a long cord. I am using an ISP Decimator Noise Reduction pedal in front of this because I was getting some line noise, but not any more. Maybe Boss can add some relaxing sounds because they did a great job of looping the music on this thing. Wait, I can add them myself with a USB card or memory stick.

A Great Device!

By Terrance Winkler

from Akron, NY

Comments about Boss eBand JS-8 Audio Player with Guitar Multi Effects:

This is a awesome unit . You can jam along with your favorite tunes. It has a tuner,metronome,looper,and it records too! Great assortment of tones can be achieved covering all types of music. The only weakness would be the speakers but hey plug in a good set of headphones and hat is quickly forgotten. Buy it you'll love it!
