I had a DOD but I was not able to use it the way I wanted. The screws in the bottom prevented me from attaching it to a pedalboard. There was a lot of rubber padding on the bottom which had to be removed, and then the biggest screw protruding out from the bottom could not be removed because it is vital to the assembly of the pedal. A major flaw in an otherwise solid and well-made product.
I’ve got a Classic Audio Effects Expression Roller G2, which also is apparently not being made anymore. It uses a normal effects pedal format. It is awesome, and exactly what you’re looking for, if you can find one. I use it with a Mission Expressionator which lets me control all the parameters and switching for my three pedals that have expression inputs.
