The B3 provides a whopping 111 different onboard DSP effects and amp/cabinet models.

These include compressors, noise gates, filters, equalizers, and octave dividers, as well as boosters, overdrives, fuzzes, phasers, and flangers, plus chorus, pitch shift, tremolo, vibrato, a sub-octave generator, and an intelligent bass synthesizer that plays along in key—even a DeFret effect that changes the tone of a fretted bass into that of a fretless. There are simulations of both classic and contemporary pedals such as the MXR DynaComp, Aphex Punch Factory, dbx 160A, BBE Sonic Maximizer, Q-Tron Envelope Filter, Moog MF-101 and BOSS ODB-3, DS-1, CE-1 and Metal Zone, as well as the Electro-Harmonix Bass Big Muff, SansAmp Bass Driver DI, MXR Bass D.I.+, Avalon Design U5, and Xotic EP Booster and Bass BB Preamp. Original effects include Zoom's Noise Reduction (ZNR) algorithm, a bass frequency-specific Auto-Wah, and a "talking" modulator. You'll also find 20 delays and natural-sounding reverbs here, including rooms, halls, arenas, plates, springs, and tape delay simulators, as well as dual effects such as compressor/distortion, phaser/distortion and compressor/auto-wah.

The dozen amp models provided by the B3 include emulations of classic tube amplifiers like the Ampeg SVT, Fender Bassman, Marshall Super Bass, Polytone Mini-Brute III, and acoustic 360, as well as the modern sounds of the Hartke HA3500, SWR SM-900, Aguilar DB750, Gallien-Krueger 800RB, Eden WT-800, and Italian Markbass Little Mark III, each with its own distinct cabinet modeling that can be used to further alter the tonal quality. What's more, you can pair any amp model to any cabinet model for unusual, and often striking effects.
