The modeling this amp does is very impressive from clean and crisp to dirty and deep with more effect than I will ever use (they all sound amazing too!!!)I have use this amp for live gigs without a problem (even having a lead who likes his volume blasting)

Most of the reservations in my previous review (see below) have been addressed by the September 2018 firmware and app updates (and by turning the volume up).Firmware: They added a very sweet "Acoustic Sim" amplifier model, to give a nice acoustic tone to an electric bass.
