I may be missing something completely elementary, btu i've run through several different configurations, and have been completely unable to get my DL4 to even power up at a club.

At home & the rehearsal space, i plug in the power supply and input/output cables, and everythign is fine. This has been done in multiple locations, multiple wall outlets, different cables, and in different positions in my pedal array. however i have tried to gig with this pedal twice, and have been unable to get it to even power up. have tried multiple configurations, even plugging the pedal directly into an outlet rather than a powerstrip etc... it won't even light up. i can place it at the end of my effects chain and it allows signal through, but will not function as a pedaal.

I've been through numerous configurations, and have had several sound guys, both house and touring, fiddle around and come up with nothing.

any ideas?
