Hi atomic, New member here. I've had the AFB for more than a year and it's an absolute stellar pedal that I use for recording as well as live. I part swapped my ceriatone OTS mini tube amp (dumble derivative) for it and couldn't be happier with my sound, and more importantly, the ease of getting it. However, I've been using the AFB as a single channel amp because the A-B Mode has a tendency of not being reliable if knobs have been bumped at any point. I've seen discussion about a lock on this front and would love for the update to come through. Any updates? Thanks again for the amazing product. Regards, Brandon.
