I've tried to use the Code 100 looper nut I'm haveing a hard time getting it iset .  As soon as I start playing, the looper start playback and it sounds like a doubliing . How do I setup the looper?

Please, tell me which output to use to run my MC212 out of my DSL40. I want to run all three speakers at the same time. 

While using the Marshall Gateway App on my iPhone 7 or SE (I'm assuming this happens on other iPhone models as well),  the "Playback" page automatically defaults to "Apple Music" when I want to add tracks to jam to with my Code 50 amplifier. 

My question for Marshall Support is: Can you make the iPhone Gateway App allow selections of tracks from locations other than "Apple Music" on the "Playback" page?

It would be great to be able to select tracks from my other files like "One Drive" or "Files".  Your competitors like the Boss GT-1 and the Spark 40 allow tracks to be added from ANY location when using their jam-along features. Limiting your choice to "Apple Music" really limits the jam-along experience on your app.

Thank you for considering making this useful update to your iPhone app.

Can someone create a preset for the Stone Gossard crunch sound from most live Pearl Jam recordings?  

Hy

I uninstalled the gateway application on my iphone because it did not work well, I reinstalled it and on the screen it tells me
( Context 3D not available posssible reason wrong render mode or missing device support ), Could you help me?

Good day,  just want to make clear, once i had a power glitch (when i turned the amp on, power button was ok, but the channel and sound didn't appear and there was a click sound that at least it tried to) i noticed then that my power cable on the rear panel got loose a little so i set it properly and now always check the cables firstly before playing.  There are no problems anymore. So can a loose power cable be a culprit of such behavior? Is it dangerous for an amp? By the way there were no sparks or cracking sounds from the socket.

Interested to know if anyone has a preset to give a harmonica a Chicago blues sound?

Always feel modeling amps lack the punch, the pick attack of an analog amp, but the CODE 100 does a good job, but it still sounds a bit like you are listening to a guitar track on a song instead of a live guitar performance.  Thats not a bad thing, the sound is smooth, it is clean, but it is different.   The cleanness of the sound is interesitng actually, the notes are far more distinct,  far less mushy and makes you play much cleaner. 

Thi is in comparison to my IValve King 212 with messa boogie pre amp,  and 6L6  power valves.   Have had it years, but havent been able to get the solo tone I want out of it, it has always sounded harsh, though the messa boogie valves helped.  This is where the  CODE 100 excells, the solo tones are very clear with none of the noise, so tapping for example stantds out very nicely, whereas with the Peavey it was feeding back and very noisy at the levels needed to get any volume.   

After a couple of days playing, the Plexi with gain is my preferd rythym sound and marshall fury with the reverb removed my prefered solo sound.  

Not gigged it,  we are just a jamming group made up of ex band members and having a once a week laugh,  but I can imagine the amp would be fine in any pub type venue. 

I will try it using the Peavey speakers over the weekend,   see what difference that makes. 

Hello, and greetings Marshall, I just bought Marshall Major III Wired from the Marshall online store at Shopee Mall. So today, as soon as it arrived here, I would like to check the originality of the product using the serial number given. May I know where can I check this?

I'm currently shopping loopers and prefer the "buy once, cry once" mentality but also don't want to overbuy only to find out my current simplistic setup cannot take advantage of a pedal with too many features.

I'm looking at the Boss RC5 and RC10R, and my intention is to plug the pedal into my DSL40's effects loop rather than in-line with the guitar input.  My understanding is that in this location, the looper will receive the clean/overdrive/distortion tone I use when recording the loop, and play back that exact tone through the power amp, and the drum functionality in these pedals will be uncolored by the DSL40's preamp.  Is this a correct understanding?  I should be  able to record a loop using my clean tone and play back a clean tone after shifting the DSL40 to overdrive channel to accompany the clean loop with an overdriven lead, right?

Where does the DSL40's onboard reverb come into play in the effects loop?  Before or after the effect loop return?  If the loop pedal I buy has onboard reverb it can apply to drum accompaniments, will the Marshall reverb also be applied to it when it comes through the amp's effect loop return?

And finally, while this isn't a 100% Marshall question... how would one go about playing into a pedal like the RC10R and looping one's tone created on a DSL40, and then when time to play back the loop content, have that output go to a more neutral amplifier while still having guitar played through the Marshall?  I can't think of a way to do that short of micing the DSL40 and pushing that input into the RC10R, then having the RC10R output to a neutral amp.  If I send the effects loop out to the looper, will the DSL40 still play if there is no return from the looper?  Can i use the effects loop send like a signal splitter at the preamp? 

I'm trying to hook the DI out from an Origin 20c amp to a Mackie Pro FX10 v3 mixer and then to powered speakers. I need the preamp channels on the mixer for mics so I want to plug the DI out to the line input on the mixer withou a gain control, it accepts both balanced and unbalanced. The result is a very weak signal compared to the mics. I'm using a TS cable because that's what Marshall says the DI out takes. Some more ther observations. 
The attenuation effects the output, the strongest signal is with the amp on the high setting. 
The master volume on the amp effects the signal strength. 
If I max the main out and the channel level on the mixer, set the amp on high, and set the master on the amp past 12 o'clock I get a decent signal but that makes balancing between the mics and other instruments difficult and also complicates stage volume.  
Is the DI out on the 20c -10dBV or +4dBV?  Would a Line Level Shifter fix this? Any other advise would help. 

Can I use Tung Sol EL34B tubes in my Origin 20H amplifier to replace the stock EL34 tubes ?

I recently purchased a code 100h.  I've noticed that with the cabinet simulation turned off, the amp is incredibly fizzy and bright.  I am running into a 2x12 with Celestion Vintage 30s.  Is there a way to tame this high-end shrillness without having to resort to running cabinet simulation through an existing cabinet?

bluetooth wont connect with my code 50 it connects for audio but cant acess amplifier settings and parameters keeps showing passkey code on my phone but wont let me enter the passkey code anywhere tried everything still wont connect to amplifer to acess my code 50 HELP!!!!!!! Jimmy Rumsey

I have a few questions:

1. A DSL40CR or 100H has 5 output jacks 1x16, 1x8, 2x16, 1x4, 2x8.

Which output do you connect a 4x12 or 4x10 cab?

 A friend has a 4x10 cab with 4 Fender V1030 30w 8 ohms speakers. I believe it comes from a Fender Hot Rod Deville. But I have researched and couldnt find an extension cab like this for a Hot Rod Deville online. It doent have a Fender logo plate on it or an info sticker on the back. It must be a clone someone built. Nevertheless it was built good. I opened the back and I didnt check how it was wired. 

2. Can you run both speakers together, (4x12 or 2x12 cab with the 1x12 V type speaker it comes with?

3. And if so which outputs are the correct ones to connect.   

Someone place help me I dont want fry my amp.

Woburn  speaker wont play loud volume when connected via bluetooth, but sounds normal when connected via optical1.

first time poster, long time tech. having experience with marshall amps I am familiar with issues stemming from problematic circuit boards (i.e.-DSL/TSL etc ) however my experience regarding this model is limited. can't say I have ever been a fan of DSP. for me ,as a player/tech DSP is a deal breaker. like the dreaded nintendo game format red circle of death, once the DSP bites it you're done.  I just seek a simple answer for my customer who bought one second hand,never re-tubed. amp lost power.sounds like a badly blown speaker (speakers test good). replaced output tubes and driver tube (original outputs tested badly). preamp tubes test good. supply voltages appear to be normal.overdrive channel LED switches from red to amber to slightly different amber but no green.  clean channel button switches normal. red-orange-green.master volume button doesn't come on.sometimes if you perform factory reset all buttons function but sound is still terrible. nice clean signal going thru to pin 7 of V7.  in between V7 and phase inverter something is haywire. my money is on the DSP board but not having a flow chart ??? tried to get a signal straight into the power amp but got nothing out. any input appreciated guys.  one thing more...i get the 2 separate heater voltages. V6 is 12vdc but the other for the remaining tubes originating at the tranny, is that standard 6.3 ? didn't see it on the schematic.

Hi, 

I just recently got the Monitor 2 headphones and everything is fine when I connect it with my Phone. But when I connect it on my PC via bluetooth and play something on Youtube, output sound is like choppy but when I connect it via cable sound is very clear. May I know if anyone encountered this and have any solution.

Thank you

I have two identical Marshall DSL 100 watt heads. One of them was starting to crackle when I turned up volume on either clean or distortion channels. It  finally quit and assumed it was just dust in pod. However  a week ago turned amp head on and neither green light for clean channel or red light for distortion channel were coming on and no sound at all from either channel coming coming through speaker cabinet. Trying to get some help on what could possibly be wrong causing me to lose sound from amp head. Thanks

Hello everyone,

I just boufht a TSL100 and the sound is spectacular on the clean and crunch channels through the 1960AV and 1960BV cabs. When the switch to lead happens, the volume knob does nothing or almost nothing and I have to turn the gain all the way down (which obviously changes the tone considerably). Everything else is brilliant. Any ideas on where I should begin? Suggestions are appreciated! Thanks
