M-Wave AnnBlackBox is an update on the BlackBox.
Key Differences and Shared Features:
Version & Evolution: The Annblack Box is considered an evolution of earlier M-VAVE models (like the Cube Baby or original Blackbox), offering a more complete feature set and improved sound.
Renaming/Branding: Some discussions indicate that "Annblackbox" may just be a name variation to avoid legal issues, although it generally refers to the newer, updated unit.
Features: Both devices offer 80 editable presets, Bluetooth connectivity, USB audio interface functionality, and a built-in battery.
Sounds: The Annblack Box is noted for having improved, more "natural" sounds and better-modeled amps and cabinets compared to earlier, more basic iterations.
App Connectivity: The Annblack Box features, or is used with, updated app software for managing presets.
In summary, the "Annblack Box" is effectively the newer, slightly refined version of the "M-Vave Black Box" product line.
I have the M-Wave Cube baby for bass which is cheaper still and its a great little unit for the price of a Donner/Rowin single micro pedal
