Marshall Jubilee Problem!

[Mike Schram]

I’ve had some problems recently with my amp where the volume drops and comes back. Sometimes it drops slightly and other it’s almost off. I’ve replaced tubes, cables etc and it still happens. It happened at my last gig on New Year’s eve and I stomped on a pedal and it came back, so it leads me to believe the problem is pedal related. Also, I run one of those “ Power All” adapters with a daisy chain cable to power my pedals.

I run all my pedals through my loop and I plug directly in the amp. Here is my setup.



Out- Digi Delay-GE7-Boss Chorus- Boss Flanger- TU2- In


Any ideas?

I’ve had problems with the loop in the past where my DD3 delay distorted my sound and was overdriving my loop. I switched to a Digidelay and the problem was solved.


Thanks

have you cleaned the jacks and Tube Sockets? I'd start there

[Mike Schram]

Yup...several times.

Just bypass your pedal chain, and see if the amp is the problem.

I had that happen on a NEW Marshall amp, and after checking out everything else the tech found out it was a bad power tube! Try subbing some known good tubes first, before doing anything drastic.
