Does changing from one wattage to another while the amp is on cause any problems?

It doesn't seem to cause any audio issues besides the obvious change in volume - but will it hurt the lifespan of the tubes or damage any components?

So what's the rule? Choose power level before turning on? Turn down the master volume before changing power levels? Or does it make zero difference?

My amp broke down and I need to get a new one because I’m already going crazy lol. I saw the CODE50 for (the equivalent of) 345$. Should I get this amp? Is it good or should I look for another options? Do you have any other suggestions for an amp around this price? I play in my room. No shows or anything like that. I used to have Fender 15G and, volume wise, never passed the 4/10.

Hi

does anyone has the settings for greta van fleet?

Code 25

I have recently been given the above amp and before I connect it to a speaker and switch it on I am concerned to know the correct protocol for connecting a speaker cabinet(s).  The speaker output sockets have no information directly next to them but a label elsewhere on the rear of the amp states "WARNING. Not to be used with speaker cabinets of less than 4 ohms"

My queries are:-

1. Is it safe (i.e. without risk of damage to the amp) to use just one speaker output as long as it is connected to a speaker cabinet of 4 ohms minimum impedance and appropriate wattage?

2. When using both speaker outputs can they both be connected to cabinets each of 4 ohms minimum impedance or are the outputs paralleled in which case would I need to work with two cabinets each of 8 ohms to arrive at a 4 ohms minimum impedance in total?

Apologies if the answer to this seems obvious but I have a little knowledge of these matters and while a little knowledge can be 'a dangerous thing' it can also lead you to be concerned (possibly unnecessarily) about getting things right!

Thanks in anticipation

I just purchased and plugged in my hundred-watt code amp head prepared to plug it into my full stack two 2 cabinets and it only has one speaker output Jack on the back I am confused befuddled perplexed and never heard of such a thing as specially for Marshall what do I do to run it to both cabinets can I use a splitter box I'm feeling like a snowflake somebody help? Lol

Hi there

I recently bought a code 25 and am inlove with the amp. One problem your app does not work on IOS. I have not tested it on android devices as I don't own any Android devices.

The app opens and everything but the sign in procedure does not work

Please fix your app!!

bonjour je me présente christopher , je viens d'acheter un marshall code 50 et je voudrais savoir si quelqu'un peux m'aider car je veux enregistrer le son de mon ampli pour pouvoir mettre mes enregistrements sur une clé usb par la suite et écouter si quelqu'un peux m'aider ce serais cool merci(christopher)

Directly, I want to enter a numerial parameter, for example using key pad windows on Gateway application, when I setup some parameter. How can I do?

Dear Marshall team,

I got my new Marshall code 25 but had to recognize that i am not able to connect with the gateway app. I am connected with the amp, but i do not see the connection sign on the left on the app.   It is also not requested to enter a code or number while connecting with the amp. The key is also always different when i am trying to connect again with the bluetooth. I am kind of desperately because I was really excited about my new amp :(

What can I do to connect with the app? I tried everything that was already suggested in the other comments. Please help me :/

Greetings from Germany,

Lilli

Hi All,

So I’ve been using a Marshall 1987X for a year now. About 2 months into use I removed the bright cap to reduce the hiss, feedback and aggression I was getting off the bright channel. 

I keep channels bridged and am getting a good loud classic bluesy tone from the amp that I definitely dig!

I want to have something to boost it with just ever so gently to get more sustain, a tiny amount of compression and a hair more presence from the sound. 

What pedal fits the bill? I want to keep away from overdrives and silicon chip based pedals

Cheers

Karan.

My MA 50C has an internal speaker that is at 16 ohms and the amp is wired for 8 ohms max.  I have a 2x12 cab that is at 8 ohms that I can plug in - BUT (and this is the question):  Can I leave the Internal speaker plugged into the amp (again, at 16 ohms) and STILL plug in my 2x12 cab (8 ohms) without doing damage or do I have to unplug the internal speaker before I plug the 2x12 in?  By my math (and this is always very questionable), it should be able to handle it because it will not make the amp go lower than the 8 minimum to get the full 50 watts.  I need another set of eyes/brain to confirm/refute.  Thank you in advance!!!

How  far can you turn this up wihtout blowing it up!? Code 50

Ive got a main  Heavy Metal Tone I use all the time. The volume in the preset is set to  1.8. I have it that low so it doesnt blow my Clean sound away when I click between the two. 

I was playing with a drummer the other day and I had the master volume up to maybe close to half and I was worried I was going to blow the speaker.

So How  far up is safe?

Hi.

Please can you (Marshall) tell me if the speaker in the CODE50 is a FRFR ("Full Range Flat Response") speaker???

Or is it an actual guitar cab. speaker (that may have been specifically voiced for the CODE50)???

Regards,

Dale.

P.S.

Of course anybody else's comments would be appreciated.

how can I show you 2 videos of the new and old code 100h head that show a strange sound coming from one but not the other
these videos were taken minutes apart and tested a few times
it sounds like a tiny fire alarm is going off with volume pushed to max and all other settings either in a preset or all down
