Can the foot switch be programmed to not remember settings on each channel, only the basic pre loaded ones? Meaninig that if it remembers that I had reverb on channel 2 of the clean sound, I dont want it to turn reverb on next time I cycle through to that channel. 

How can I reinstall all the 100 factory presets (and overwrite all my selfmade presets) ???

I recently purchased a Code 25 and uploaded some presets to it. When I first select the preset it sounds great, but if I go to another one for a little bit and cycle back, the sound is completely different. What could cause this? The only thing I'll change when playing is the master volume. It typically gets very boxy with a lot of bass and lose mid/treble sound. I have to turn it off then on to get it back.

Hi,

A few months ago (Oct 2022), i buy in Reverb a Marshall Valvestate Bi Chorus 8280 and when i turn on, all feels ok, but one day i note only work one speaker. I change the cables and the other speaker are fine and i think the problem was in the output jack.

Finally, i found a tech who tell me he can check it and repair. When the amp is ready to go, i pay and check it in their local store and i notice a weak sound, but i thinked it was the room. The L and R speakers out works now but the problem comes when i push the chorus and the volume rise and have more body.

The guy tell me is because the amp only works in stereo when chorus is on (great sound and body), and in mono (sound lack and low volumen) when put off, but i don't believe it and that's why I'm looking for an answer here.

P.D. When i receive the amp, the first thing i do, is change the valve, so this is not the problem. If i disconected one speaker (L or R), sounds good and the chorus doesn´t affect the tone.

Please help me.

Hi Everyone,

I bought a Marshall Studio Vintage Head in US where we have 110V voltage and 60Hz frequency. If I want to use that amp in Italy, where the voltage is 220V and 50Hz frequency, is it okay if I only change the currently mounted (US-rated) fuse? Or do I need to get a transformer? I am not sure if the amp is only rated for 110V / 60Hz...I like to think that it was built for a range of V and Hz that works for Italy / Europe as well, being made in UK.

If the fuse is the only mod I have to do, then I can just use a campatible power cord to plug it in?

Forgive my ignorance, and thanks in advance.

how to add a GRAMS preset?

After many many many failed attempts to update firmware it finally showed successful on the update page but now the screen permanently shows do not switch off or usb not connected and is unusable, no buttons work ,completely frozen.

I just purchased a 1999 JCM2000 DSL 50 in mint condition .  It worked for an hour great no issues.

Turned everything off and came back later to find the following:

Channel led lights do not light.

Pedals in the effects loop have no effect.  Just had a Fortin Zuul in the loop.

Cannot change the channel with footswitch nor the front panel channel button. 

I do get good signal out of the cab but am stuck on the lead channel.  

All the tone stack controls work fine.

I can change between lead 1 and lead 2. 

I have pulled the chassis and inspected fuses and all seem good. 

Nothing looks burnt on the boards nor did I find any loose connections.

I removed all connections so only the cab was connected and have same issue. 

Any suggestions before I take it? 

I thought the effects loop would have still worked being I get signal out of the cab. 

Very confused as I have never seen something like this before. 

My Marshall AMP not working. Please help :-)

Hello,

I own a Marshall JVM 215c. I purchased this when I was living in Portsmouth. I didn't have much of a chance to use it as I was also studying for a degree at the time. I then moved up North. So 7 years later I'm in a position to crack back on with guitar (finally).

So I dust off my JVM 215c. Turn it on. Nothing happens. There is sorta a thump sound when I turn the power on. But then nothing.

Does this sound like a valve issue? And if so, is it easy to fix myself? Or does this amp need a professional to look at it?

Kind Regards,

Lee

I have a Apple laptop with chrome installed.Tryed to install the latest firmware but it goes to 100% and sticks.The new amp is now useless .Please could you help.

My Marshal-Emberton bluetooth speaker is having issue with sound. Speaker's conneted and charging, but unable to hear any sound.

Wanting to swap out the g12m for a g12h. Speaker is stuck to the mounting board. Best way to pop it loose. Is it glued?

Hi there! 

Can you please tell me which amps the PEDL-91003 is compatible with. I have heard it can be used with the DSL100H Is this the case?

What footswitch should I use when Pedl-10010 (P803) are discontinued.

Regards,

TC

Why when logged on i cannot see answers to questions ?

I just bought this amp yesterday. Everything works, but the speakers have been changed to Ovation Audient 40 #9732 8ohms. Should I keep them or go tothe original Celestions?

my code 25 is frozen, nothing is working. The display shows marshall - MCU: 1,47

Connection to the pc is working, update is starting, and then please wait restarting code.

Nothing more. The code 25 is not restarting. Power off and on is not the solution

What can I do?

Hi all,

I have a brand new Code 50 + Footswitch - got them today.  I have saved 3 of my own presets to Bank A 1 2 3.  No problem. Also assigned the tuner to a switch.  That was all fairly straightforward.  

However, I am unable to assign any other (new) presets to any of the other banks. When I follow the exact same process I used for Bank A - The footswitch just defaults to one of the amps, stock presets (all of which sound nasty).

I've watched the tutorials. At the moment, I have only 3 presets of my making on the switch and no, apparent way, of using any of the other banks.

Am I missing something obvious?

Cheers,

Mike

Can/should you write directly on the white strips above each switch on the PEDL-91016 6 button foot switch?
