I just got a new CODE50 and am extremely pleased with. My problem is everything on the Gateway app works, but the GAIN, MIDDLE, VOLUME, and PRESET knobs on the amp don't work. I'm really pretty new to this so I'm not sure if something is wrong or I'm doing it wrong but every other knob works correctly.
Hi Arren, When you use the knob, does the amp respond in any way? If not, please contact our team at Servicedesk@marshallamps.com who will advise further.
