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.
Thank you for you comments, we are sorry you seem to be having issues, regarding the feedback you get when allowing the string to ring out you will just need to adjust the noise gate, this will allow you to ajust how much signal comes through when letting the guitar ring out, this is not a fault the amps are designed like a valve amplifier and act in a similar way
We have not heard of a low volume issue on the clean sounds, can you confirm you have the preset volume up high, as well as the master, each preset will need to be adjusted to a level you would like.
I would recommend the amp is looked at if you believe there to be a fault, if you could send a video out the clean volume to firstname.lastname@example.org , that would be helpful.
I am also having same problem with distorted sound as chord or notes fade 4-5 second. Sounds staticky and crunchy. Not good when using clean tones. When I turn off amp, then it doesn't happen, but loose a lot of volume... I have also raised and lowered noice gate, but to no avail.
Any help or info would be great.
I'm a new user of the code 25. Some of the sounds are a little buzzy as they decay, especially the lower notes. I think this partucular buzzing is just the limit of the technology that you get on a pretty inexpensive practice amp. Try switching of the preamp, power amp and cab (all the modelling) and see if it goes away. You'll then know that its just the way it works. I've had other cheap modelling amps (Fender mustangs and LT's) that are exactly the same.
However I agree that the noise gate is very buzzy as the sound start to decay. It's more noticable on the clean tones. I suggest you switch it to zero if you can stand the small amount of background hiss this will give you.
