Very easy to use. Plug & play de-mute.
Be careful if you make the very big sound, it is a bit limited power level, the red LED "does not play louder" appears very quickly (remember the name sorry).
Maybe because I play active. I do not know.
The sound is good to play, but to save ca not hold water: it's like a wave, it is very odd (again, perhaps due to my active bass, but I tested with parallel range a Peavey which I know not the name that did not vibrate like that score!
Really to put aside once semi-pro.
