I had this Marshall code 50 with muffled sound. Even of i turned to max volume the sound is too low or weak.

its a hit or miss opportunity to make it work, sometimes the amp is working good then after minutes of playing the sound turns awful. 

it happened after i updated to latest firmware, im suspecting its a bluetooth board error or a bad firmware update.  Tried reseting, reupdating to no avail.

Does anyone tried to remove the bluetooth board? 

I bought a speaker from eBay I would like to know if it is genuine 73400553T21567D0044749 is the serial number

How to update my firmware using a macbook connected to marshall amp

I recently purchased a code 50. Unfortunately the sound keeps cutting in and out. I've tried to get ahold of Marshall directly and I'm seeing to have a lot of trouble getting through. Do you guys have a direct number?

I use D# standard almost exclusively.  Can you change the tuner to use that as the default?  It's a pain having to change the tuner EVERY TIME to that tuning.

Hello!

I have a Code25 and during playback, it just stops sounding.

This happens several times... the connections are good, the proof is that the tuning works perfectly, the signal is going, but there is no sound...

I have to turn it off/on and it sounds again... but after 5-10 minutes, it happens again...

I tried updating the firmware, I tried resetting to factory settings, I tried resetting the presets... it works for a while, then it happens again...

I think it's not hardware, but software... is there any update or firmware to fix this??

Please help me!
Thanks!

How do you register new amplifier, to activate warranty.

it looks broken

Bluetooth,AUX ,RCA lights always on, can not do anything

I've bought this year a JCM 800 2210 Lead series head amp from 80's. I've bought it by second hand and the previous owner didn't have the foot switch. I've searched until now but I haven't figured out which foot switch is suitable. Could you please explain to me this? 

The amp is single channel in the front, but has the foot switch channel behind. 

Thanks for your help!

Hi,

Is there any differences between a 2009 and a 2024 edition of this amp ?

Would really appreciate any info on this topic

I upgraded the firmware on my Code50 to the latest Version 1.48. When I try to activate bluetooth with the REV/POWER buttons there is no blue LED in the EXIT/STORE button and my pairing on the PC shows no CODE. Also, it seems the thge reset with the PRE FX button doesn't work.

The Code 50 is basically new with very little use..

Hello I bought
Marshall DSL20 HR,
got a footswitch with it
and a cord:
marshall pvc 0.85 sqmm x 2 cores wonderfull vn(lf)

My question is this a proper enough speaker cord?
the speaker i connect to is
1 x 8 ohm Seventy 80

The reason i ask is because cable looks a bit thin, so is it safe to use, wouldn't wanna blow some transformer or something.

Great little amp. I plan to use it via the emulated out into the band PA.

Question ... What sort of 3.5 mm jack lead do I need ... Mono or stereo? ... It will be going into a mono input on the mixer.
