Hiss/Fizz - CODE 50
1

vote

Bought a CODE 50 two weeks ago and LOVE the tones - great reproductions! But I have the hissing problem as well. Quite noticeable as a chord or note decays. At first, thought it was normal 60-cycle single coil pickup hum, but it is not.

Read similar Posts on the Forum, so tried the firmware update and it did not help. Noise gate not really an effective alternative, either.

Team Marshall, any other solutions in the work Again, otherwise I love the amp and want to keep it.

Thanks.

Hi Michael,

Thank you for your message, sorry you seem to be having issues with your Code. We have not come across this with the Code 50, have you tried another guitar and lead, it might be worth contacting the store to let one of their engineers to take a look at.

Also try a Factory reset, by holding down the amp button while switching on the amp.

Hi guys. Had the same issue.

If you reset to factory defaults it goes away on my Code 25 firmware 1.3

It has something to do with inserting USB  as it stays on after that, even after powering off.

 

I reset mine and taped the usb port...

I actually returned my first code amp when I first had the issue... then found that resetting fixes it - alex newman 20 Nov 2018 at 02:07 PM

Hi, I've got a code 50 and exactly the same problem. Seems to have occurred when I put the latest update for firmware,  have just tried a factory reset and it's the same.  Apologies if there is a fix mentioned above somewhere and I don't quite understand about taping the usb could you expand on that.  Otherwise love the amp but the hiss is really annoying, tried it o 4 different guitars, single coil noisles tele, p90 custome, hotrails and humbucker and it's the same on each so sure it's the amp.

Look forwards to hearing suggestions

I'm having the same issue, but through my CODE100 2x12. I've played a Gretsch with Humbuckers throught it, and nothing. Played my Tele and I'm getting bad hiss and noise on my neck and bridge pickups. Now, I'm played same Telecaster through other amps and get nothing. For some reason, my amp cannot and does respond well to single coils? Also, I played same Tele through another CODE amp and it was fine. Like others have said, would love to know any kind of fix with this.

 

Thank you,

Marlon

I'm also having the same problem with a CODE 50 I bought about two weeks ago.  Tried the factory reset, to no avail, and my firmware is up-to-date.  I noted that the hiss is less prevalent on certain presets, some presets don't seem to have the hiss at all.  If anyone comes up with a solid answer, I would sure like to hear about it.  Otherwise, great amp!
