Hi, I am using CODE25.

I updated the firmware to V1.41 yesterday, but since the update, Bluetooth is no longer automatically connected.

There is no problem right after pairing Bluetooth according to the way suggested in troubleshooting.
However, after rebooting CODE25 not recognize the device again on the iPhone's Bluetooth settings.
So to use the Gateway app, I have to pair it with REV and Power each time
These problems have been seen since the firmware update and before that there was no problem at all.

I hope to know if there is a way to fix the Bluetooth connection problem or roll back to older firmware.

Thanks

Hi,

to whom it may concern.

I would like to ask a help with the preamp layout in JVM 410 (2007). I have found this online but it says "Assumed". As you know the tubes on board starts with with V1 a power tube to V4 so it is hard for me to assume.

Could you please confirm if this diagram is correct (bottom right of the picture)?

thanks in advance,

I saw in a demo video that Marshall will soon have a 6 button footswitch for the DSL 100HR.   Does anyone have any idea when that will be available?

Hello

I have bought the code 50 from a friend that has added his own presets and I would like to bring it back to the original presets state

How do I do that

Thank you

Looking to get a shimmer tone out of my Code 100, anyone know how to set that up out of existing presets?

Should the stand by switch be on or off when I play with headphones

Has anyone come across any Joe Bonamassa presets?  I know he's all over the place at times - but I like the song "Drive" and what he's doing there.

I've stored presets on my Code Amp foot controller, can I reset the footcontroller to it's original patches.

My phone connects to the amp perfectly with Bluetooth, and can listen to my music etc.

But my gateway app cannot find my CODE amp. I've tried everything. deleted and reinstalled app. reset my amp.

Any help would be very much appreciated.

On my Code-25 I had a setting I liked to use - preset 7 - Volcano, but now it's different (maybe changed after a firmware update?)

Does anyone know what the manual settings are to emulate Volcano (previous pre-set 7)?

Where can I find a schematic for a DSL 40C? I have an open short somewhere in the power circuit.

How to turn off the noise gate on the pre sets?

I tested the instrument cable with my cable tester and it passed.  HOWEVER, the cable I learned is actually defective.  I used a different cable.  The point is try using a different instrument cable even if your cable tester recognizes one as being okay.

Ever since I connected a USB cable between my CODE 50 and set up this account I cannot get sound to come out of the speakers. My amp is all but dead.  HOW do I reboot or reset my amp to make sound come out of the speakers when I jack my guitar into it; turn the unit on; slowly raise the Volume GAIN and Master volume and hope to play something?

Does anyone know?  Thank you for your time.

All,

I have seen this a lot but just wanted your feedback.

The great amps that I have played through, such as Mesa Boogie, Carvin, Catagory 5, etc, are awesome

but they never seem to have enough gain or sustain.

Is it cool to use an ODC Fulltone or a Tube Screamer in front of a Dirty Rhythm, or Lead channel?

If so, what kind of set up's do you use?

TIA,

Jerome

Hi everyone,

I getting ready to utilize an old Valvestate VS100 Combo. I need a foot switch that will allow me to utilize the three distinct channels on the amp.

Clean, OD1, and then Lead or OD2. Which switch can I use.

Thanks in advance.

hello, my bi chorus 200 seems to go quiet while playing, in both channels. The sound becomes weak and distant and sometimes almost goes altogether. Then the next time it might work fine for a while but always goes eventually. It’s a mid 90’s amp. I think it is powerful amp and I hope I can fix it. Anyone know what could be wrong?

Whenever I turn my amp on it just buzzes, and doesn’t pick up the guitar at all. It’s not the guitar because it still does it unplugged from both guitars I tried. Tried different outlets too. Can anyone help?

I'm wondering what year this DSL 15 h is I'm about to purchase V01002A30U. Thanks for any help, I'm so excited to own my first all tube Marshall weather it this one or a brand new one
