I use two of them, one goes from the guitar to the pedalboard and the second from the pedalboard to the amp. This means 11 meters of cable run, not counting the patch cables! The signal loss is really negligible, although I do use a buffered pedal at the end of my pedal chain! It gives me autonomy to move around all over the rehearsal studio and - hopefully soon - all over the stage too, without compromising my - precious - tone! They are really REALLY durable! Did I mentioned they look the part too?
