Code 50 chorus not working – tips?

All Questions

the chorus on my Code 50 is not working. I’ve had the amp about half a year, but not really used the chorus until recently.

If I turn the chorus on, the sound changes a little bit, but it’s not a chorus sound – although the speed option has an effect.

If I switch between CLS and VIB a few times, sometimes the chorus will suddenly kick in, and sound good, but if I turn it off or change presets, the chorus reverts back to its barely-there sound.

Has as anyone else suffered from this? Any tips? Thanks.

Hello, I'm having the same problem on the code 100H head. I will try the factory reset tonight, as well, and report back. - 10 Sep 2018 at 03:22 PM

Apologies for not following up on this. I did not do a factory reset, because I didn't want to lose my presets. However, the chorus works now, on one preset — I use very few presets, one has chorus. This one preset is based on a Plexi amp, and has a very clean tone. I have not tried the other factory presets in a long time, nor do I remember the details of the problem — whether it was a factory preset or one of my own, other settings etc. - 11 Sep 2018 at 08:46 AM

I did the factory reset last night, it didn’t solve the problem. On mine, when you turn on the chorus effect, all that happens is a slight tremolo effect. To reliably activate the chorus, you must scroll to one of the others, like tremolo, then roll back to chorus, then it works. Seems like a software glitch. - 11 Sep 2018 at 11:03 AM

Hi David,

Thank you for your message, we have not come across this, have you tried a factory reset, you can do this by holding down the amp button while turning on the Code, please be aware this will reset all your presets by doing so.
