Zoom B6 Bass Multi-Effects Processor

zZounds Gear Experts Say...
Multi-effects built for bassists! Zoom's B6 is packed with effects, amp and cab models, a powerful looper, and drum patterns to jam with -- plus two inputs.

With four DI models and advanced multi-effects, the B6 gives you freedom to explore entirely new sounds.

SUPER-FAT BOTTOM END
An analog circuit, combined with the DI section vastly improves the low-frequencies of your instrument.

SUPER-FINE TOP END
With an 88.2 kHz effects processor, double the rate of others, the B6 has your high end covered.

FOUR ICONIC DI MODELS
Zoom meticulously modeled four iconic DI boxes to give you a wide variety of tonal options.
- Tube 1: Vacuum tube DI character with rich harmonics and thick low frequencies.
- Tube 2: Vacuum tube DI character with a clear attack and tight low frequencies.
- Solid State 1: Delivers moderate compression and sharp tones for electric bass, while protecting against the loss of low frequencies when playing an upright bass with piezo pick-ups.
- Solid State 2: Solid state DI character with a clear tone and little distortion.

BUILT FOR YOUR SIGNIFICANT OTHER
Separate inputs allow you to A/B switch from electric bass to synth or acoustic bass, and back again. Both inputs let you change the impedance from 1M to 10M ohms, giving you a cleaner tone for upright basses equipped with piezo pickups.

DETAILED AMP MODELING
The B6 features 11 of the best amp models in history, plus a couple of new ones.

BUILD YOUR STACK
The B6 provides simulations of 12 classic bass cabinets, each with three variations based on mic positioning.

LEGENDARY ZOOM SOUND
The B6 also delivers the ultimate collection of Zoom's legendary effects, along… read more with 10 new ones.

JUST THE RIGHT TOUCH
The 4.3-inch color touchscreen lets you drag, drop and rearrange effects to build the perfect signal chain in seconds.

PLAY MODES
The four Play Modes on the B6 will change the touchscreen and footswitch layout to give you quick access to the controls you need.
- Effect Board: This mode provides a visual representation of your pedal chain. By clicking the assigned foot switch, you can turn on or off an effect in your patch.
- Bank/Patch: This mode lets you scroll up and down through your Banks and Patches by clicking the corresponding foot switch.
- Memory: Ideal for organizing your patches for performances, the Memory Mode allows the foot switches to activate one of the 4 patches in each bank.
- Looper: Use the Looper to add layers to your sound.

LOOP, RECORD, REPEAT
Create loops and recordings up to two hours long, saved directly to an SD/SDXC card for instant access and recall.
*45-second looper without SD card.

BACK BEAT
Select from the B6's 68 rhythm patterns in a range of styles, tempos and time signatures.

RECORD VIA USB
Connect to your computer via the micro-USB port to record directly to your DAW.

HANDY GUITAR LAB FOR B6 APP
Connect the B6 directly to the Handy Guitar Lab for B6 app via Bluetooth. Using the optional BTA-1 adaptor, wirelessly connect your iPhone or iPad as a secondary interface for your B6.

Accessibility for the Visually Impaired
The first multi-effects processor that allows accessibility for the visually impaired, the B6 Handy Guitar Lab for B6 app features VoiceOver and VoiceOver Gestures.

Zoom Guitar Lab
You can also browse the Zoom Guitar Lab to easily save, edit and load patches.

NEW AMP MODELS
- Sun CB: Features clean bass and bright high frequencies.
- Monotone: A solid-state combo amp perfect for jazz, featuring a round low-mid range with a calm overall tone.

NEW PREAMP & EFFECTS MODELS

Clear Drive:
This original ZOOM Clear DRV preamp uses a linear phase filter in the distortion path. As a result, phase interference is eliminated during dry mixing, providing a clear drive.

Super Low Preamp:
A ZOOM original preamp for super low sound. Using "missing fundamental" acoustic science, SpLoPre is equipped with a bass enhancer, which emphasizes the low end of every note. With a Lo EQ and a negative one octave sound, a super low-end tone is produced.

Djent Preamp:
An original ZOOM preamp recommended for Djent sounds. This preamp combines an undistorted low-end with a strongly distorted high-end to provide a crisp, intense distortion even with a down-tuned 5-string bass.

1073 Preamp:
A thick, warm sound of a vintage mic preamp with transformer distortion.

Solid Preamp:
Modeled after a console's solid state mic preamp, the SolidPre delivers tight sounding harmonics with the ultra-low frequencies cut out.

Bass Analog Octave:
ZOOM's original octaver using an algorithm based on the operating principle of analog octavers.

Bass Standard Synth:
ZOOM's original bass synthesizer sound with adjustable filtering detail.

Bass Synth Talk:
This effect produces a synthesizer sound similar to a talking modulator.

Features:

- 4 DI outputs; 2 tube and 2 solid state models
- Integrated A/B switcher for seamless instrument switching

I love my B6. I am a professional bassist. My credits include, David Sanborn, The Brothers Johnson, DAP - The Digital Audio Projekt, George Duke, Eric Marienthal, Chris Standring, Candy Dulfer, Agape Spiritual Center, The Jazz Junkies, Mindi Abair, Jennifer Batten....I love the B6. I use the XLR out for all my gigs to go to the front of house as it sounds better to my ears than any DI Boxes I've had to use. The tuner is big, well lit and easy to see on dark stages. The Octaver tracks super great even down low. The chorus is thick and clear, the fact that I can tweak the overall board eq a bit before going into a backlined amp is great because in places like South Africa and Estonia, sometimes the amps aren't the best and need a little more pre dialing. Once I opened for Earth Wind & Fire, playing with Dave Koz and had to play the show in a big ampitheater on a 75 watt practice amp because the other guy who shall remain nameless, needed both SVT rigs in case one went down, so all they could scrape together was a practice amp..I went xlr out to the front of house and asked for bass in my monitor. When I heard what was coming back, I boosted the lows, cut the mids and boosted a tiny bit of hi's and tweaked the practice amp as well and the gig went just fine. These features alone make the B6 worth it in my book, but there's a lot more to it than just these things. The DI button gives you different curves to the shape of the sound which works good for various situations too. Aldo… read more the fact that I don't have to worry about pedal knobs not being in the exact right place for effects and that I can throw the whole board in the front pocket of my gig bag and head out is convenient too Mostly, I love the sound! I contacted zoom with 3 suggestions I thought would be awesome: 1) if along with the loop player/recorder you could send a click/drum machine track down a seierate mono line to a drummers mixer/in ears setup. It would be great because then you could have it running on a certain song, loop on the fly in time with live drums because he's locked yo.the internal rhythm nachine, and the keys, guitar & the entire band are in sync and now you can play over your own grooves adding plucks or slides to your looping line, then shut it off and jump on the bridge or the chorus section and go back to it fir the verse. I think it's a good idea anyway. They didn't think so.2) if they lost the efx bypass button and made it a fifth effect, so you'd have 5 effects, 4 is great..one more would be ideal!! 3) if they put two pedal switches on there and added ,better a Bluetooth or USB-c corded page turner for iPads Anyway the B6 is a pro unit and I personally use it for every gig and session. Peace out,André
