I layed out holes on a 7$ tayda 1590dd for a 5 effect multi pedal. I had a real hard time drilling but when i finally got it done and tried to put the pots in i realised that the enlosure is so thick that i cant screw the washers on :/... its the first time i ever got a 1590dd from them, as anyone else had the same problem ? I am wondering if i just got a dud enclosure or if all of them are like that ... Thanks
