Loud! On batteries and LOUDER plugged in!Straight out of the box; I was amazed at the quality of sound, and the accessibility of features from the unit control panel.…that’s just the beginning!Controlling the Katana Air with my iPad is simply amazing! There’s a sound library with pro settings, which are changeable and save-able!I recently used this live with a microphone. We had several loud people on stage. The sound tech was very impressed and I could hear myself just fine! The wireless guitar function has been flawless!Using the cable input option makes this a great pedal platform. Sometimes I use a CryBaby and the amp sounds exactly like I want.I use this just about every day and I’m very happy to own it!Highly recommend
