I bought a bunch of these, in various different lenghts, from short to long in an attempt to make more space on my packed Harley Benton spaceship 80 pedal board. As both ends of these cables are at an angle, they sit flush against both the pedal power input and the power block output. Its surprising how much more space this creates by allowing you to place rows of pedals closer together. I also loved that by buying some short ones too, it significantly cleaned up the tangle of long power leads that were running around my board.
Pros.
Inexpensive way to tightening up a packed pedal board.
Available in various different lengths
Cons.
can’t think of any.
