I just purchased my DL4 delay pedal and every time I turn it on my tone dies, my volume drops and my high end gets dull as can be. I spent $275 on this pedal and adapter so I would really like some suggestions on how to make it not suck!!!!!!!!!!!!!!! I have a really nice handmade tube amp and every other pedal sounds amazing through it. thanks for your time.
