Hello,

I took delivery of a Code50 last Friday, and already I have noticed a major flaw. I have updated the firmware, and it didn't solve the problem.

1. On many of the presets, there is what sounds to me like a slight buzz or a distorted sound as the chord is being held after about 4 or maybe 5 seconds. Obviously, this isn't going to be good when recording.

For example, I have been using many of the clean sounds, such as, American Clean (preset 32). This is a prime example of the unwanted buzz as the chord fades (only 4 or 5 seconds). There are so many more presets that also have this problem.

The issue occurs through both the Code50 built-in speaker and my Beyer Dynamic DT100 headphones. Using headphones proves that it is not the internal speaker at fault.

I can email a sound byte if you need one.

The last thing I want to do is re-box the amp and return it for a replacement only to have the same issue happen with the next unit. So, please can you let me know if this is a widely known fault because, if it is, I will unfortunately have to send it back for a full refund.

2. A second issue worth noting here is that the clean sounds are not very loud. When wearing headphones, I have to increase both volumes to 10, but I can still hear the strumming of the actual guitar with my plectrum coming through the headphones. The volume on the clean sounds are too weak and definitely not loud enough when also playing through the Code50 speaker, not just the headphones. Conversely, the distorted rock sounds are really loud when the volume is set to a low level, but the clean sounds couldn't be more opposite.

It will be a shame if I return the unit because I love the app and the ability to back up presets and also search for new ones.

Many thanks

Hi everyone, so I recently purchased a Marshall Code 25 off of a friend and the amp is perfect for what I need; however, every now and then it starts buzzing out of control. I'll turn it on in the morning to start recording and the buzz is so loud, it almost overpowers my guitar sound! I have tried 3 different guitars, acoustic and electric, bought a high-end Ernie Ball cable and even moved house and the buzz is still there! I was able to fix it in the past by updating ad overwriting the firmware and then leaving it unplugged for a few hours to a day and that solution worked for a long time, but now it's buzzing again and nothing I've tried has made any difference. Another thing, its plugged into the same power strip as my PC and monitor, but the power strip I've switched to is a $50 uninterruptible machine of a power strip that looks like a space ship, to no avail. Also, when I turn my amp on, it makes my PC monitor kind of short-circuit and the picture freezes and fragments for a split second and then goes back to normal. I have tried every possible amp setting, and only setting the noise gate to 80% gets rid of it, which is unusable. I have also tried other power outlets and it only works when it's in a separate part of the house. I should also mention that the sound does go away when I turn the preamp button off on the amp, which again, makes the amp unusable. The house I moved to is also relatively newly made and has had various electricians here to sort out any previous power issues in the past few weeks. I'm at my wit's end and I seriously need some help!
