Amplifier emulator and effects for bass

ZOOM presents B2 Four

The 4 rotary encoders allow quick adjustments of the effects parameters and output settings. Cross navigation buttons help you check the pedal with facilities. The B2 Four can be used as an audio interface 2-in / 2-Out by connecting to a computer or smartphone with your favorite amplifier effects and models.
With a patch library and effects in continuous expansion, bassists can continue to expand their sound with the "Handy Guitar Lab for B2 Four" app (for iOS), available for purchase on the Apple App Store.
This original Zoom Clear DRV preamplifier uses a linear phase filter in the path of distortion. As a result, the phase interference is eliminated during dry mixing, providing a clear guide. The original zoom octaver uses an algorithm based on the operating principle of analog octavers. This effect produces a synthesizer sound similar to a speaking modulator.
