Pedalboard problem

[Lamb_of_God318]

Hi everyone.
I have a Warwick Gigboard RB23100 and my effects chain is Digitech Whammy > Boss DS1 > Digitech RP50 > Behringer Graphic EQ > Chord Chorus > Chord Delay. Today I turned on the board and the overload light came on instantly. I took one pedal at a time out of the chain and discovered the overload light only comes on when the Boss DS1 is plugged in. Is the DS1 done for? I'm no tech head, I'm useless when it comes to this sort of thing, so anything you can tell me would be great.

Thanks

What are you using to power all those pedals?
How about trying a battery in the Boss DS1.

Hello. The pedalboard has a built in power supply, everything but the Whammy is running through it. I'll get my hands on a battery tomorrow and give it a try. Thanks for the advice.
