i bought a Code 50 amp pre-owned early 2024 from a local Guitar Center outside Chicago IL. it had been working perfectly up to and until i was editing some of the stock sounds to use with the footswitch and found that the pots on the amp, (OUTSIDE of the master volume) stopped performin to any manual manipulation. i did a reset (losing all the presets i'd set up...but i digress) that was unsuccessful. i sent it to a local music store which claimed to be able to fix it, but could not. i downloaded gateway as a workaround and while it manipulated the patches via bluetooth, after several minutes in a particular preset, the different parameters would just wildy scroll indiscriminately between the different functions and suddenly there was no sound from the amp. i COULD/CAN switch patches and the next patch sound would come up as normal, but the same order of problems ultimately occured again.
the music store suggested there's likely a problem with a software 'chip' that's causing it to do that; but i'm reaching for a solution. i like the amp a lot and it's my first 'professional' guitar amplifier, so it would be greatly appreciated if there was some answer/solution to this issue.

I have a similar problem with my Code25.
It was probably caused by myself during my attempts to create a ridiculous footswitch by short-circuiting some electrical points behind the buttons in the PCB. Cheap ass...
I might have lost some screw or spacer in the process, and if the pot's nuts are overtighten during reassembly, the buttons in the panel don't move anymore (pre-amp, mod, etc), and the values in the display do that weird random dancing, without affecting the sound.
I had to disassemble the amp again, and disconnect/clean/reconnect a couple of small flat cables. This solved the numbers dancing and the pots started to work again.
Due to my poor skills on reassembling things without leaving anything behind, I cannot tighten the pots as well as I wanted, so the panel is a little bit loose. Very little.
So, if you're not as clumsy as I am, I'd recommend opening the thing up and check the flat cables connections. It's not a difficult job and may solve your problem.
Ask for help if you don't feel comfortable to do it and search for safety measures to avoid electric shock.
Anyone familiar with laptops or computer assembling will probably be able help.
Good luck!
