104 comprehensive effects are included, with the ability to layer up to five simultaneous effects for truly unique patches, and the B2 Four sports high-quality 24-bit A/D and D/A conversion, including 128x oversampling as well as 32-bit DSP for high-resolution effects. The B2 Four features plenty of I/O, including a balanced XLR output with ground-lift switch for noise-free output, a 1/4" input with selectable impedance, a 3.5mm aux input, a powerful headphone output, expression control input, and USB-C connectivity for using the B2 Four as a 2x2 audio interface, connection to the patch- and effect-expanding Handy Guitar Lab for B2 Four iOS app, and an optional power source.
Loop, groove, jam, and rehearse with B2 Four. The 60-second built-in looper allows you to build grooves, while the 68 beats from the onboard rhythm machine are the perfect companion for practice.
- Tube 1: rich harmonics and thick low frequencies
- Tube 2: clear attack and tight low frequencies
- Tube 3: clear and glossy sound
- Solid State 1: moderate compression and sharp tones
- Solid State 2: clear tone and little distortion
- Solid State 3: elevated mids and low treble, meant to replicate the Motown sound
A 3.5mm aux input can be used to jam along with an external track, while the expression input lets you connect an external control pedal to modify parameters. The 3.5mm headphone output is powerful, providing 33mW per channel into a 32-ohm load.
- 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, the SpLoPre model is equipped with a bass enhancer, which emphasizes the low end of every note. With a low 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 ultralow frequencies cut out.
Amps
- 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.
