Tried to update my firmware and tried three cables. None are even recognizing the amp on multiple computers. Tried to reset the settings on the amp and nothing helped. It seems as if the USB port is not working at all.

I am able to connect my phone to the amp via bluetooth, but for the most part am not able to sync the presets in the gateway app to the amp.  On occasion it will do it, but most often not.  The tuner and playback work fine.

Hello,

I obtained a Marshall Haze 40c and was wondering if there were any current-production amp footswitches that mimicked the 4-button footswitch for the amp that is now discontinued? I have seen some on reverb, but they are a bit pricey when shipping is added to the mix. 

Also, im a bit tech-savvy and wouldnt mind making my own. I understand what it takes to make a 2-button channel control, but unsure how to wire a 4-button switch. Any schems out there ?

I can download and run the firmware updater on my Win 10 laptop - it then asks me to connect my CODE 25 amp. I connect the amp using a USB cable - then I see the message "An error occurred: An error occurred getting the device information from your CODE. Please try switching your amp off, and then switching it back on again."

I switch it off and on - no good. Same problem. I connect the CODE amp before running the firmware utility - same result. So I don't even know what firmware is currently in there. Is this solvable? BTW - the USB cable works, as my Marshall CODE Live Editor has connected to the amp using it.

Thx

Hi- I have owned an AVT50 from new. The footpedal no longer switches to overdrive and while the switch on the amp still works the red overdrive light does not come on. I live in south east London; where is the nearest place I can get this fixed?

Hello...I have a JCM 800 2203 that I purchased back in 1981 and I wanted to replace all the tubes in the head after all these years. My amp has many hundreds of hours on it between practice and hundreds of gigs back all through the 80's.  I assumed that I had the standard compliment of Four EL84's in the output stage of the head...Everything I've read stated as such, and all the You Tube Bias Procedures led me down the same path....SO I ordered a matched set of TAD 12AX7's (3),  and four EL34's. Well, much to my suprise, when I took the back metel cover off the head, I did not find four EL34's...What was installed for power tubes back in 1981 was 2- 6550's, and 2- 6L6's. Both larger than the EL84's. Can anyone tell me why they (Marshall corp.) would do this...is there any special reason? I DO NOT want to change ANYTHING about the tonal characteristics of this amp. I would sure like a little enlightenment on the what's and the why's. I am truly facinated at discovering this..Thaks to all...Randy
