Marshall Silver Jubilee 100W reissue: low volume output, fizzy and glitchy

[Symphonichrome]

Hi everyone - this is my first post here - I am glad to have found this forum as I bought a new Marshal Silver Jubilee 100W reissue and, as of today, the output is low volume, fizzy and glitchy

Am I looking at a bad tube or something more serious?

Hey, @Symphonichrome!

Maybe try plugging a cable from the effects send directly into the effects return. That’s a common fix for output issues in the original Jubilees. Let us know if that helps.

I already have pedals in there

Thank you for the welcome

Past that, likely a tube. Start with preamp tubes by changing them out 1 at a time. Then go to,power tubes. My guess is it is that.

Actually upon reading this agqin, I see it says "new". How old is it? Mention this to the seller for warranty.,

Going with tubes, take to a reputable repair shop for a once over... Unless you are a tech, peace of mind...

Yea New?. If it's new, as in new just bought new use the warranty.

Yeah - about 2 months old

Will check tubes tomorrow and if it is not the tubes, will open a warranty claim

Check bias too if you are comfortable doing that....

Did this issue just start happening, or has it always sounded like this?

LOL I wish it was that but, some elves must have fixed it overnight

Perhaps tube socket? Very weird.

Most times when I've had this sort of issue with an amp that I know has good tubes in it (new or recently retubed), the amp itself was not the problem. Here's what was:

- oxidized pickup selector switch on guitar
- jack not fully inserted in pedal
- faulty stomp switch on pedal
- dirty pedal jack
- faulty pot on pedal
- failing battery in pedal (better to use high quality power supply)

Anyways, that has been my experience FWIW.
