Hi  I  think you misunderstood my question- I don't want to download, I want to save the settings I have tweaked in case my amp breaks and I need to re-download them later.

original question : Is it possible to upload and save presets via USB? How do I do it? (I don't have smartphone so cant use phone app).

Hi,

I recently bought a Marshall DSL20HR head and a Marshall 1936 Lead 2x12 cab. 

The head has a cab emulator out, so I hooked it up to my audio interface and was playing through my pc monitors. I turned up the volume and gain on the ultra gain channel and a strange buzz/noise came from the head when I would strum a chord or pick a note.

I only noticed this because I had the level on my interface low as I was just testing the cab emulator out. I have alos tested this with the head not plugged into either my interface or the cab and still get a strange noise/buzz.

As this is my first valve head I'm not sure if this is just something that happens when you turn up the volume and gain - as the amp is being pushed harder, or if there is a fault with the head and I need to take it back to the shop I purchased it from.

I will link below some video of the problem. The first video sounds worse than it is as I put my phone directly on top of the head as I play. It's not the signal noise from the amp that I am worried about, it's the rattle when I strum chords or hit notes...

Any help would be greatly appreciated, I'm probably just over reacting, but it would be good to get some reassurance.

Thanks! \m/

Can you guys please help

Hi, i have just aquired a haze 15 head in great nick.

please anybody could you advise on what marshal power tubes are used as in maker ?

Also they use three ecc83 the first being a different code ( this is the one with the aluminium cover) is this the higher gain one? if so could i swap for a lower gain with no problems.

Also has anyone upgraded the speaker that is fitted ( marque) ? if so to what just interested

Thanks John

Like apparently everyone else, my Code 25 "forgets" to turn on Bluetooth, and I have to restart the pairing process all over again, everytime I want to play.  I have to delete the pairing from my phone, turn on bluetooth pairing on the amp,  and rediscover the amp.  EVERY FREAKING TIME.  Where's that update to the firmware?

Hi,

I got new 2525C.How shoud DI OUT work?When i connected DI OUT to sound card input,there was silence,both in STAND BY,LO & HI mode.At that time,from SEND signal is in any mode.

I have had my DSL40 for about 5 years now.  Today I turned it on and have zero gain.  The volume seems to work but no distortion, even on ultra gain.  I am assuming this means the tubes need to be replaced, but the poerp or preamp tubes?  Or all of them?

when I connect the app on android with the bluetooth amp and I want to load effects edited by other people, the effects return
by default, and when I deactivate the bluetooth again the edited effects appear in the library of the gateway app. Can not be
used when connected? I do not understand what happens.

Is it possible to control and make changes to the existing preloaded patches of the Code App via the USB port connected to a Windows 10 Laptop?

or the Marshall Gateway App works only with Android/iPhone via Bluetooth?

thanks

I love my Code 50 amp but lately, it's having a problem where there is no sound coming out of the amp after a couple minutes of turning it on. The only way to fix the problem is to turn it off and on. However, this only fixes it for a couple minutes. I've already instaled the latest firmware.

I am having the same problem as many others regarding automatic bluetooth connectivity. Please, Marshall. Sort this out, you've had long enough to deal with this. Maybe we buyers should demand our money back.

Hi! I would like to use the effects on a Line6 Firehawk with my DSL20CR using the 4-cable method.

Is this method possible with DSL20CR?

I connect with Gtr->FH input, FH FX send->Amp input, FH FX Return->Amp FX Send, FH left out->Amp FX Return

I hear the sound when I push the FX Loop button on the Marshall remote. However it seems to bypass the preamp, i.e.

nothing happens when I change volume on the Marshall. I thought the 4-cable method meant I could mix the pre-amp

with the effects through the FX loop. What am I doing wrong or is this method not applicable to this amp?

Best, Hans

Tried out the effects loop over the weekend and whether I run one pedal through it, or loads, tried different cables, power supply or battery, the loop adds a high pitched whine to the sound, which makes it pretty unusable.

I'm going to re-try a load of things, again different pedals, batteries and cables, but do Marshall have any suggestions?

Also is there a way to change the level/mix of the effects loop, or is it fixed?

Hi,

I recently purchased a Code 50 and have been trying to connect it to the gateway app on my Android phone. The phone connects to the amp successfully via bluetooth and I can stream the audio out to the amp directly using Spotify but when I go into the gateway app, it says "Not Connected". I tried the "Scan for Amps" button but it doesn't find anything. Any help is appreciated.

I would like to bypass all effects/config on my MG15CFX and just get a straight amplification from my line6 multi-effects processor.  

Hey, just bought a new MG 30 GOLD series and was wondering if anyone has any tone settingdto share. Have several different guitars to play through with everything from a 3 single  Strat to a Les Paul with fat humbuckers. Prefer a heavy, overdriven sound but willing to try anything. As it is unless I'm on the clean channel everything sounds muddy. Trying to get a bit better technically before ifreak my wife out and drop big $ on a tube stack. Thanks in advance!

I researched 1x12 open back vs. closed back vs. ported cabinet guitar cabs. My experiment with my Code 50 amp was to remove the back without unplugging anything so I could here the difference between closed back and completely open back. The amp really came alive with a lot of punch and presence while ridding the boominess that occurs. I removed the power cord socket and cut a square the same size as the speaker. This was an improvement but I liked the complete open back sound better. I then cut the back out more leaving just enough stock to support the existing power cord socket hole and protect the electronics inside the cabinet. I will continue with cosmetics such as painting inside black and/or add a grate for protection. To my ears the amp really came to life open back. I will keep it this way. It is an easy experiment to try without sacrificing anything, just remove the back cover screws and pull the back away. If you hate it you just refasten it and leave it original.

High-pitched 'Whining' noise coming from my Code 50 power amp ~ should I return it? Settings: Amp volume on 0, Master volume at 6 or above ~ sounds like it could be an artifact of a failing Class D power circuit? I hope to hear from the Marshall moderators soon, before my 30 return window expires!
