Frequently Asked Questions

The mic channel has a simpler EQ – just volume and reverb – designed for basic vocal reinforcement, lacking the guitar channel's broader tonal shaping.
It uses an OTG connection, which might require a USB-C to USB-A adapter depending on your interface; compatibility can vary.
Using all effects will reduce battery life; expect closer to 2 hours with moderate volume and all effects engaged.
