Build a versatile bass rig in one compact unit with the M-VAVE TANK-B All-in-One Multi-Effects Processor for Bass. Designed specifically for bass guitar, the TANK-B combines bass preamp modelling, cabinet impulse response (IR) simulation, dynamic processing and time-based effects, giving players a flexible range of tones for practice, recording and live performance.

The TANK-B features nine bass preamp models and eight cabinet IR slots, alongside a comprehensive effects selection that includes a noise gate, compressor, three modulation types, delay, reverb and a three-band EQ. Its flexible effects architecture supports customised signal chains, allowing players to shape and save tones suited to different playing styles and musical settings.

With 36 editable presets arranged across nine banks, the TANK-B offers convenient access to a variety of sounds. The companion M-EFCS app and computer software provide additional tone management options, including preset editing, sharing, import and export, firmware updates and custom IR loading. Four dedicated footswitches provide preset and effects control, while the integrated tuner adds another useful feature for bass players.

Beyond its effects and modelling capabilities, the TANK-B also functions as a versatile audio hub. A balanced XLR output supports connection to mixers, PA systems and studio equipment, while USB-C connectivity enables computer audio-interface functionality and recording. A dedicated phone-recording output, Bluetooth audio and headphone monitoring add further flexibility for practice and creative workflows.

Powered by a built-in rechargeable battery offering up to approximately 12 hours of operation, the M-VAVE TANK-B combines portable convenience with a broad range of bass tones and connectivity options in a single, practical processor.
