This here cable is something that you should really consider buying yourself, in case you happen to use multiple effect boards or so. I bought this cable for that specific purpose and it hasn't failed me, not even once yet.
The length of this product is good: 60 centimeters. Imagine this situation: You are playing on stage and you have a lot of different effects that you need to use while playing the song you're playing. You don't want to just stay in your place the whole time while playing, you want to move around a bit. That's why you've got this cable. You can place your pedal boards a bit further away from each other so you can truly rock the place.
Your dream aside, it's good for other reasons as well. In case you want to connect multiple small things into one chain and then link it to your amp, for example. The length is just perfect for that.
The only downside I've seen while using this, is that the jacks might loosen up a bit but that's something that everyone can do. Just tighten it with your fingers again and you're golden.
