I have a Deluxe Memory Boy. When it is plugged in, all the lights come on and no sound comes out of the pedal. The dry signal is the only thing that can be heard. What is wrong? Any Ideas?  I use the original DMB adapter.

Hi, fernando here from Argentina. Same exact problem. Is it a common issue with this pedal? In mine its like the signal gets just almost nothing affected, but if you pay atention you notice it modifies it just a little bit, almost inperceptible. The lights all work and the only ones really working are the “blend” and “gain” knobs.
Is it possible that it is a problem with the switch? like it doesnt route the signal correctly? Is it a simple fix?
(sorry for the rusty english)

Just return it or send it for repair. or you could try unplugging the adapter, then plugging back, check that all the connections are ok, and move all the knobs. if nothing happens then return the unit
