I recently bought this amp for band rehearsals as it was a bit more powerful than my previous marshall 15watt, it is lightweight and with presets plus footswitch I was hoping to ditch my pedal board. We rehearse in a village hall which has a hearing aid loop system and the Code 25 seems particularly sensitive to it. If the volume turned above a quarter turn it triggered significant feedback particularly on settings with high treble. Unfortunately the loop system is in a tamper proof cabinet which we are not allowed to touch. Has anyone else had a similar problem and know a workaround?
My other issue was bluetooth pairing with my phone but reading through the Forum it appears this is a "feature". If I can't resolve both these issues it is going back to the shop next week to find an alternative amp that works for me.
Hi Colin,
Thank you for your message, have you tried the Code at the same levels not in the hall, if there is not Feedback, then there won't be a fix as it could just be the hall causing this issue.
There is a Firmware update to fix the Bluetooth, please follow link below
