Hello there!!

I recently bought a used Code 50. It needs to be reset I believe. I can't get the tuner turn on. I can't adjust any settings.  It plays, but sounds a little muddy at times. Would really like to be able to adjust the different mods and amps and what not. Thank you. 

Hello, All:  I have a CODE 50, about 18 months old.  I usually play a "clean" preset, like JTM45, and when I take a break from playing and come back, the preset sounds like it has had distortion induced and/or gain set higher.  This can happen in just a few minutes, or when I leave the amp turned on overnight.  To rememdy, I turn the preset selector know one click right or left, and it clears it up.  I've heard of one other person who has this problem, too.  Anyone else out there experience this?  If so, do you now of any "permanent" remedies?  TIA!

I would appreciate any support you can give me. 

I recently purchased a DSL20CR; when I received it, I heard a strange buzzing sound in the studio, which the other Marshalls did not have, 

I contacted the local Marshall dealer. He told me that it is a common issue, and other similar models had the same behaviour. Still, customers report that regular activity will work itself out until it disappears, in other words, with regular use.

And although it sounded strange to me, on the supplier's website, a customer reported this, I contacted him, and he told me that one day the noise stopped.

Well, today has been several months, and the humming continues,

It starts at 46 dB, but with increasing volume and gain, it reaches 90 dB without any instrument connected, only the power socket.

I have tested it in several places and with regulated electrical outlets, even with filters and signal stabilisation with an inverter. The power supply is optimal, but it has the same behaviour.

I asked the supplier's technician to check it, and then the report says that there is nothing abnormal, that according to him, all the components are correct, and there is nothing that generates problems for its use.

So the supplier tells me that they offer no warranty and no replacement and that this is normal for this amplifier.

I decided to replace all the tube tubes with new ones with the exact specifications.

I bought the Tung-Sol kit and another JJ for this amp, both for power gain and preamp. 

After the change and tried both options, it continued with the same sound, noise; in a previous mail to Marshall, I asked to confirm if this amp needed to do any BIAS process; well, the answer is no; it is not necessary. Still, I compared the tubes before and after, and they had a similar value. at 10W, they gave 24 mA, and at 20 W, about 57mA

I know there are similar problems, and I have read in forums about component changes to solve the problem. Still, those forums also refer to issues with the emulator output, but this is working correctly in my case.

What can you recommend, is there anything I can do to fix it?

I appreciate any help you can provide.

Update to below- The iPhone 11 IOS 15.02 update fixed my issues. The app is working properly now & I'm very happy.
____________________________________________________I had a fault code & couldn't connect Gateway to my Code 50 a few months ago when I purchased it. I tried deleting the app to reload but when I reloaded, it was only accessible via the App Store & wouldn't appear on my Home Screen. I could connect for awhile. Recently it seems since the IOS 15 update to my phone, it no longer connects manually or automatically to my Code 50. The app is useless to me. I've search for an alternate app from another source that is compatible with the Code 50 but there doesn't appear to be one. The Gateway app and Bluetooth connectivity heavily influenced my purchase decision. If I had known the app was useless and I would have to physically go to the amp and try to dial in each sound, I would have just bought a fender. I really feel you should take my amp back if you can't correct the problem. 

Hi I have an Origin 50 head and I want to know what tubes for v1,v2,v3 should I purchase for replacement. Also there is any specific order to place them in.

Bought a marshall acton II today and I'm unable to play music from my phone on it. It does not show on airplay either while connected on app. I suspect it's broken on ios15. Hope it gets fixed soon or Im requesting a refund as right now it's just standing as decoration. 

Hi

I am thinking about buying this amp.

Is the effects loop engaged by deafult. i.e no F/S connected

Can Effects Loop be switched  on/off by a Line 6 HX Effects (as well as using HX for channel switching).

Does Effects Loop   "tone suck" much?

Any experience/advice greatly appreciated

Thanks

Hi everyone.

Since iOS does not support AptX I was curious what codec is used when I connect my iphone (12 pro) to my Stanmore. 

Turns out it uses SBC. By any mean it is not the end of the world, tho now I'm wondering if I have a malfuctioning BT module. 

Hello Guys

I just got a PEDL 91009 foot controller for my Code25. Impressed with how well it works and how useful it is (considering it connects with a normal guitar cable).

However the documentation for the 91009 is pretty poor and consists of a single sided page in the manual. I have found a few things that I can't find documented and I wonder if anyone else has found anything too.

Firstly, In the manual is says that in switch mode you can assign which blocks can be switched on and of with the three foot switches. This is great but what isn't clear in the manual is that this is universal and not per patch. i.e. if you assign button 3 to switch on the tuner then on every patch button 3 will swich on the tuner. It's the same with the tap tempo. So this means if you want the tuner available and tap tempo, then you can only switch on and off 1 effects module. Not the end of the world, but not clear in the manual. It's a shame there wasn't 2 buttons specifically for these functions.

Secondly. I had to look through this forum to find out how to reset the settings stored in the 91009, maybe it is documented somewhere in the manual. but I couldnt find it.

Thirdly. I discovered that if you are in switch mode (to switch on and off effects blocks in a patch). If you press and hold button 1 to 3 the 91009 changes to the patch stored in that bank position, but remains in switch mode. This means you don't have to come out of switch mode, change to the new patch in that bank and then go back into switch mode. May be useful for some people, but I couldnt find this in any manuals either.

Overall an impressive foot controller (for what it is). Has anyone else found out anying more it can do?

Can I get a manual for my series 9000 from Marshall?

Ive been struggling with this too, first the amp starts with irregular noise, then makes a high noise sound and stop working, I tell the store to replace and they denied, they says they are not responsible for this issue and says I have to ask for warranty with marshall but I cant contact you in any way. This is very sad I saved money for a long time to buy this because I believed marshall was a good brand, and as I see you are not taking any action to solve this. Please help me.

My code 25 cutts out after maybe just a second but when I connect headphone they work OK. Any ideas?

I bought a DSL1CR as a practice amp recently, sound was cutting out so sent back and bought another replacement DSL1CR from another vendor.  Received the replacement -- same issue, sound cuts out.  Goes from a 4 to a 1-- then back again... round and round we go..  Have done troubleshooting w/ cable & guitar (brand new Fender Telecaster) -- those aren't the issue.  Thoughts?  I hate to return again-- love the sound... with the caveat: when it works;) 

Any one else hearsd of this issue/ how to rectify?  

Thanks! 

Hello, I bought a Marshall CODE 25 yesterday, and so far I love the sound and feel of the amp. But I am having the same issue that alot of people are having, I can connect to the amp via my phone's Bluetooth but the amp will not show up in the Gateway app.

I have tried everything in the FAQ troubleshooting guide, nothing works. I can play music to my amp but that's it. Feels like a problem with the app and not my phone.

Are you reading the forums, Marshall? You need to take a look at your app, seems like it has some compabillity issues, it's working for some people but not everyone. 

I have a Samsung Galaxy S8.

Please fix.

Hi there. There is a very audible metallic ringing coming from what most likely sounds like the tubes when the gain or master volume is turned up to a usable level on any power setting. There is also a high-pitched scratching type buzzing (not 60hz or ground buzz) at higher master volume levels even with the tilt, presence, and treble turned all the way down.  It sounds exactly like the problem user Chris Holtmier asked about in his question on Dec 27, 2018. It is brand new shipped, and I noticed this immediately out of the box just 30 mins ago. I have tried other speakers, guitars, guitar cables, position in the room on the floor and tightened all the screws as well as re-seating the tubes. It's probable that the tubes are microphonic after shipping but because of the way it is built, I cant reach the tubes to do the tap test when its plugged in. Although the response to the previous question in mention was stated as "We have not come across a rattle on the Origin 50 Combo" it seems that this is a recurring problem with a few of them as he was referring to a post on another forum about the same kind of noise on an Origin 5 as well.

I guess my question is, why doesn't this work properly brand new and is there anything besides a re-tube that you can suggest to fix the problem without returning it?  I can post a sound file if needed. I usually re-tube with JJs anyways (which I suspect would fix the problem) but for now its actually cheaper to drive a 6 hour round-trip on a weekday to a GC than a $100 re-tube that possibly still might not fix the issue.

Other than that, I do really like the amp. I can tell that I would really enjoy it without the noise. I enjoy the effects loop, line out, gain boost, the tilt knob, and especially the vintage styling. It reminds me of a bluesbreaker. I dont play anything other than lower-wattage cathode-biased 6L6 or EL34 and I love pushing them to the max.  With a Rat going straight in I had a lot of fun with it before I noticed the noises again. I'm willing to admit its just a random lemon but maybe it's just from UPS handling and tubes being the way they are. I am going to play it side-by-side with the same model and check that theory. If its just the tubes I will def get the same amp again.

Is there any place to request presets?

What are the best EL34 tubes to use to lower overheating problems in the JTM60 head? And what is the recommended bias voltage setting also.

Hi y‘all, no question, just a personal update.

Have been playing two Code50s now for about three years (one for home-use and gigging, the other one for rehearsals, one the clone of the other), and haven‘t had any issues with them.
Now decided to upgrade to the Code100 combo, so I also bought two of them (same idea like said above). First impression was „more headroom“ and a bit „kind-of-more-airy“ open sound with the Code100. In comparison the Code50 sounds a bit more „compressed“.

So, gonna keep the 100s and give away the 50s. Looking forward to rocking the world with the new amps. 

Salve a tutti ho un Marshall 25 code.Il problema è  che quando sono attivi i preset in sottofondo si sente un fruscio continuo e interferenze più alte del suono della mia guitar.  Come posso risolvere il problema. 

Grazie
