Hi, after turn on my CODE 25 at very high volume with a mic turned on I almost got deaf. I turned off the Amp in 1 second... BUT, after that all the low tones/frequencies are distorted/buzzing/ugly dont know how to explain (E string with or without Cab, Amp, Mod, Rev, Del), they are buzzing coming from any Guitar or even music coming from the Bluetooth ... High tones sound fine. I tried to reset the amp and did a firmware update but I still have the issue. Also i tried several guitars, usb cables, guitar cables and even my PC but I still have this distorted low tones. Could anyone give me any advice besides going to the maintenance?

Thanks!

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. I just bought Marshall 1959 HW and it's constantly humming when it's on. I have Wizard Modern Classic Amp and ENGL Powerball 2 and they don't hum like that when ON. Is it normal? Also when I strum a chord very loud mechanical noise going out of the back. Check the video I shot to hear how both issues sound:

Hi,

I recently bought a Marshall DSL20HR head and a Marshall 1936 Lead 2x12 cab. 

The head has a cab emulator out, so I hooked it up to my audio interface and was playing through my pc monitors. I turned up the volume and gain on the ultra gain channel and a strange buzz/noise came from the head when I would strum a chord or pick a note.

I only noticed this because I had the level on my interface low as I was just testing the cab emulator out. I have alos tested this with the head not plugged into either my interface or the cab and still get a strange noise/buzz.

As this is my first valve head I'm not sure if this is just something that happens when you turn up the volume and gain - as the amp is being pushed harder, or if there is a fault with the head and I need to take it back to the shop I purchased it from.

I will link below some video of the problem. The first video sounds worse than it is as I put my phone directly on top of the head as I play. It's not the signal noise from the amp that I am worried about, it's the rattle when I strum chords or hit notes...

Any help would be greatly appreciated, I'm probably just over reacting, but it would be good to get some reassurance.

Thanks! \m/

I recently got myself a Marshall Valvestate 8100 head, which sounds amazing for a hybrid amplifier. Now there is one problem with the amp, and that is that there is a low buzzing sound when I turn it on. It does not get louder when I turn up the volume or gain, and it doesn't disappear when I switch channels, which means that it can't be the pre amp tube that causes the problem. I don't use a grounded power socket, but my other amp (an Orange Tiny Terror) doesn't hum so I don't think there is a problem power wise. My guess is a bad soldering joint somewhere in the amp, but I have no idea where to start looking. Is there someone who can tell me how to get rid of the buzzing? And how do I identify a bad soldering joint?

Cheers, 
Brian

Ok, the buzz, fuzz I and others noticed (Its Real). First before you ask I tried the cable and the guitar on my Crate Amp. The notes ring like a bell No fuzz or Buzz.

So that eleminats my guitar and cable.  I notice if I use eather the Acustic or Natural Pre Amps on my Code -50 the BUZZ / Fuzz dissipears. So I assume its not a hardware issue with the Code 50. I think its a software issue. Is it possiable to fix and down load  new Pre Amp Modelse to fix the problem? 

I would love to get this fixed! Its annoying!

A couple of weeks ago I bought aforementioned amp. I was very happy with it, no issues so far, but today while playing I noticed a weird buzzing sound that my amp makes whenever I play an A note on my guitar. I tried different fret position, plugging in my other guitar and even moving the amp in case something else than the amp itself was making the sound. Nothing helped. Did anyone else had a similar problem? Any ideas what might be causing it?
