Show full description »

Take the sound quality of the B series, plus the convienence of the 500 series, add the optimised design to the mix. The result is a amazingly affordable package with knockout performance. The New B1 from Zoom will make your bass sound much better and more versatile.

Clear and solid bass sound thanks to 96 kHz sampling

The sonic frequencies generated by an electric bass are about 40 to 600 Hz, but harmonics go all the way up to the ultrasonic frequency range. The ZOOM B1 offers ultra-high resolution signal processing with 24 bit/96 kHz sampling, rivaling the best rack-mount processors. The dynamic, wide-range bass signal retains its full impact resulting in clear, powerful tone that retains a distinct presence.

ZFX-3 -- the new-generation 32-bit DSP

The heart of any multi-effect device is its processor and decoder section. ZOOM elevates performance to the next level with its newly developed ZFX-3 chip. Its 32-bit architecture means outstanding performance and smooth, detailed signal processing. Fine nuances of fingering and touch come through without any deterioration.

13 different bass amp and stomp box modeling choices

Whether you want the massive sonic push of an all-tube amp, the sweet and mellow tone of a vintage model for melodic phrasing or the sound of a high-power wide-range modern amp, the choice is yours. There are seven bass amp settings that range from Rock and Pop to Fusion and Jazz. Plus, five unique distortion pedal sounds as well as a tube preamp for adding warmth are also available, letting you create exactly the bass sound that you want. Freely adjust the mix between drive sound and original sound to create deep distortion for real punch.

46 dedicated bass effects

Eight modules designed for bass guitar offer a total of 46 effects. A limiter/compressor lets you control peaks and ensure that levels are matched, while the three-band equalizer makes it easy to taylor your sound further. Auto wah is indispensable for playing that funky sound, and the octaver impressively enhances the low range. A defret effect gives you the special tone of a fretless bass. Detune produces a chorus effect with moderate amounts of modulation. Other studio-class effects include a long delay with settings to 5000 ms and a harmonized pitch shifter.

Bass synthesizer

The built-in full-fledged bass synthesizer uses an internal DSP sound source with triggered operation. Select one of three waveform settings (sawtooth, square, PWM) and create deep, punchy bass synth lines.

40 preset patches reproduce the sound of the pros

The unit comes preprogrammed with settings for duplicating well-known amps and stomp boxes, settings that are modeled on the signature sound of famous rock bass players, as well as totally original ZOOM effect sound creations. Right out of the box, you can enjoy professional-quality bass guitar sound. And to store your own creative sounds, a user-defined set will store another 40 patches.

User friendly interface

Editing an effect is as simple as choosing the patch with the selector knob and adjusting the parameter with the value knob. Let your imagination roam without being hampered by complicated controls.

Integrated drum machine with PCM sound sources

Realistic drum sounds derived from PCM sources are arranged in a variety of rhythm patterns for different musical genres. The 40 rhythm variations include the steady 8-beat of Rock and Pop, a funky 16-beat, "Jazzy" 4-beat, and many more choices. Rhythm training on your bass guitar has never been more convenient. A tap key is provided for easy direct tempo input.

Built-in auto-chromatic tuner for bass

The bass guitar tuner can be called up instantly. Mute tuning output offers further convenience. Bright LED indicators make the readout easy to see on a dark stage.

Ultra low noise

A signal-to-noise ratio of 110 dB and a noise floor of -98 dBm mean that background noise is virtually eliminated, resulting in clean, transparent sound. ZOOM's proprietary noise reduction technology (ZNR) is also built in, to completely shut out unwanted noise during playing pauses.

Fits in a gig bag

The compact size and weight of the B1 make it ideal for those who want plenty of effects and great performance without having to carry a lot of gear. The reinforced plastic body can withstand the rigors of use on stage and on the road. The stylish looks are also highly functional with the flush surface able to distribute pressure evenly. The unit feels great when you pick it up and equally stable when you use the foot controls. This is the kind of product design that you can get only from an industry leader like ZOOM.

AC/DC allows use just about anywhere

Thanks to its circuit design optimized for low voltage operation, the unit will run for 12 hours continuously on a set of four IEC R6 (size AA) batteries. The AC adaptor (AD-0006) can be plugged in for extended studio work, whereas on stage you never need to worry about AC power.

Optional foot switch allows remote operation

When you connect the optional foot switch (FS01), you can switch patch banks or perform tap tempo input with your foot.

Expression pedal support adds further versatility

Connecting an optional expression pedal (FP02) lets you adjust volume, wah, or pitch shift in real time. But going beyond conventional pedal functions, you can also adjust the mixing ratio of direct sound and drive sound or freely control the modulation rate or other delay and reverb effect parameters.

Dolphin Music brings you the best music gear at the best price. We are committed to superior customer service and have extensive product knowledge. However, in today’s market we may not always be aware of all the price fluctuations of the products we sell. So, we offer competitive price matching.

Price Matching requests may not be combined with any other promotional discounts, specials or other price incentives.

Prices and price sources you have found which do not meet the above criteria or in which incomplete or inaccurate information is provided to us, will not be approved for our Price Match.
