It is a digital multi-effects for bass complete with lots of effects and amp simulations some known (or sometimes less).
The connection is simple and efficient entry and exit level guitar, XLR output, a jack for expression pedal and an extra USB port that lets you use the pedal as an audio interface.
The case is sturdy but the inside is more cheap (I had to change the two switches that were reliable enough, thank you to JM by the way).

UTILIZATION

Configuration is very simple and familiar for this type of product, it can engage in discovery without reading the manual. This is very concise but clear and easy to navigate.
Backups are very easy to do and can happen very quickly a good bank of presets. on the other hand is a shame that the USB port is used solely to exploit the possibilities of the beast interface (very limited, but I found the recording like that!) And do not edit the presets (for those who like to see the pattern of action of the compressor, for example ...).

SOUND QUALITY

Regarding the effects, nothing really transcendent: the amp simulations are not very good, but can sometimes change a little grain (although the term is not necessarily the best choice) or changing a little consistency overall your sound effects themselves are often quite cheap, but the intelligent harmonizer and compressors are doing quite well.
I use it primarily with a Cort C4 (active) and the result is pretty good, but I do not abuse effects.

OVERALL OPINION

I have this brave little for almost four years and it holds up. But she is primarily a DI and tuner, I use a single preset on stage (with amp simulation and a compressor).

I appreciate the compactness and robustness of this pedal, I deplore the slight lack of musical effects which we often prefer not to even use them.

Nevertheless, I am very happy to have it, it makes my life easier on stage (I never use it in the studio though) and can restore the bass much better than many DI cheap.
