I can download and run the firmware updater on my Win 10 laptop - it then asks me to connect my CODE 25 amp. I connect the amp using a USB cable - then I see the message "An error occurred: An error occurred getting the device information from your CODE. Please try switching your amp off, and then switching it back on again."
I switch it off and on - no good. Same problem. I connect the CODE amp before running the firmware utility - same result. So I don't even know what firmware is currently in there. Is this solvable? BTW - the USB cable works, as my Marshall CODE Live Editor has connected to the amp using it.
Hi, I have just taken receipt of a MG102cfx. Could you please help me with some suggestions for Rock, Blues & Metal settings please? . I'm still kind of new to these amps and really want to discover what they are capable of. Thanks inanticipation.
Ive seen 2 diferent presets on preset 00. Mine has EL 34 Heaven and some has Screamer that has a Boston-style sound. Are there two versions of the Code 50 amp?
Is there a reset sequence on the Code 50 amps?
Does Marshall make a 3 button foot switch for a DSL100H?
Hi- I have owned an AVT50 from new. The footpedal no longer switches to overdrive and while the switch on the amp still works the red overdrive light does not come on. I live in south east London; where is the nearest place I can get this fixed?
I would Like to play this amp before I buy it but none of the local guitar stores in the Tampa Florida area seam to have it could you recommend someone else please and also is this amp a good blues amp
how do I notice my preamp valves need to be changed?
thanks you! :)
can you provide me with a history of my jcm 900 4501 amps
what year was it built?
where was it built?
Hello...I have a JCM 800 2203 that I purchased back in 1981 and I wanted to replace all the tubes in the head after all these years. My amp has many hundreds of hours on it between practice and hundreds of gigs back all through the 80's. I assumed that I had the standard compliment of Four EL84's in the output stage of the head...Everything I've read stated as such, and all the You Tube Bias Procedures led me down the same path....SO I ordered a matched set of TAD 12AX7's (3), and four EL34's. Well, much to my suprise, when I took the back metel cover off the head, I did not find four EL34's...What was installed for power tubes back in 1981 was 2- 6550's, and 2- 6L6's. Both larger than the EL84's. Can anyone tell me why they (Marshall corp.) would do this...is there any special reason? I DO NOT want to change ANYTHING about the tonal characteristics of this amp. I would sure like a little enlightenment on the what's and the why's. I am truly facinated at discovering this..Thaks to all...Randy
I have a DSL40C which I think is faulty but don't know what the problem is? I'm fairly inexperienced and don't know much but the sound that is coming out of it is very abnormal. The amp is only 6 months old and just suddenly started to make a loud noise that would continue even after I turned it off! The third time it happened it sounded like a siren. This would occur about a minute into playing. On full power it was on standby and making a light crackling noise and I wasn't game to turn it on again. I've tried different leads and powerpoints and it has not been resolved. Could it have something to do with the preamp?
How can I see the Firmware version on the Code 25? Also can you display somewhere on the Download page exactly what the current version is?
Can you confirm the latest Firmware is v188.8.131.52
I have read that JVM can handle 2 cabinets at the same time.
1. connect 2x12 ( 2 -> 16ohm speakers in parallel ) into 2x16ohm input ( 8ohms )
2.connect 2x12(2->8ohm speakers in parellel ) into 2x8ohm input ( 4ohms )
Both connected at the same time. it looks like JMV OT is designed to handle it. I would like to confirm if that is save.
I have a JTM 30 2 x 10 combo that I purchased used in 1999. It has Alnico Blue speakers, can you tell me definitlively if they are original to the amp? Thanks.
Hi, I have bought a used Marshall amp JCM2000 TSL100 but the tubes must be replaced so my question is what kind of EL34's should I buy I mean what are the original tubes that are in the amp when he goes out of factory?
Are Marshall AS50D amps compatible with a Fishman preamp on my accoustic guitar. I have ordered a AS50D through JB HI FI in WA Australia
thinking my preamp was a Marshall. It hasn't arrived yet so I am naturally anxious to the question of compatibilty.
Thank You Chris
Hi! I'm using the Jmp-1 midi rack-preamplifier and I'm loving it so much, except the fact it takes about half a second to jump from preset to preset, which in a studio situation is no problem, but in a live situation can be annoying sometimes.
Is it just my device having this problem? Any way to fix this?
I have a problem with my jvm205h. I can hear a rattle while I am playing. It seems to come from the tubes could anyone tell me what I could do to fix this or is that normal?
Absolutely can not get the Marshall Gateway app to work with my Marshall Code 50. I have found the device (amp) on both my Galaxy S7 Edge and IPad Bluetooth settings. I have been able to pair them both to the amp. I get a prompt to use the code to pair the device. I hit ok. When running the app it says not connected even though I am. The amp Bluetooth light is solid though the app says not connected. None of the app parameters effect the signal. Am I missing something simple here? Ive registered the amp and loaded new firmware update.
