Frequently Asked Questions
The mic channel is usable, but the small speakers won't provide a lot of headroom; it's best suited for quieter vocals and spoken word in smaller spaces.
Yes, there's a footswitch input, but the functionality is limited – it likely only toggles a single effect or combination, not full effect chains.
The USB-C port is mainly for recording output (Rec: OTG), not for audio input; it's designed for connecting to a computer for basic recording purposes.
