Hi,

Has anyone had a problem using the Cyber-Twin SE and the Cyber Controller where the master volume occasionally resets to zero?

I have a 2007 CYber-Twin SE and a 2002 Cyber Controller and VERY RANDOMLY, starting about 4 months ago, the master volume will reset when I turn the master volume to zero in between songs with the Cyber Controller. Again, it's very random, happening 1-3 times a night at differant times of the night and at differant clubs so there is no consistancy in the problem such as after the amp gets warmed up (it can happen at the beginning of the night or at the end).

I had a 2002 Cyber-Twin head and NEVER had that problem.

I did have a Fender certified tech check out the amp and pedal this week and he spoke with a Fender rep who said that the problem happens when the power supply to the Cyber Contoller is disrupted (due to an RDL light issue) then the Cyber-Twin can reset itself to zero. I HAVE recently had an issue with the power supply to the Cyber Controller, after 6 years I think it's about done. But that happend only recently within the last month and if what the Fender rep said was true then my pedal would've reset itself and blinked "00", which it never has during one of these episodes.

I also have had trouble finding a replacement power supply for the Cyber Controller, Fender & other parts sites don't list one for sale so I bought a replacement with the same specs on e-Bay this week which works fine!!!

I will see if that is the solution but I also wonder if maybe the power supply was going bad and while not completely interupting power and re-setting the Cyber Controller, it may have occasionally sent an under powered signal to the amp which reset the master volume without affecting the pedal.

Just curious to see if anyone else has had a similar issue and if so, what did you do, if anything, to resolve it?

I'm also curious if anyone has any idea what else it could be if not a power supply issue.



Thanks















I didn't find the right solution from the internet.
