Quality from Planet Waves as usual - the cable remains in tact even after stepping on it way too many times and running over it with my chair - although, it's fatness comes in handy here (as it really prevents your chair from going "over" it).
An important note for all interested in this item. If your guitar/bass has an input jack on the bottom (all Les Paul guitars, for example), this cable will do wonders and will pose no issues whatsoever.
However, if your input jack is right below the bridge, you might (and most likely will) find it kinda hard to "get in" (if you know what I mean...) - in all seriousness, the "fatness" of the cable can be a bit unnerving as you really have to push it in order to get in the slot. Once you do get it in, however, you feel safe that the cable won't randomly detach itself and it takes quite a bit of force to take it out.
For example, this cable fits perfectly in my ESP EC-1000, however, I REALLY have to push it to fit in my Ibanez S470.
Regarding the sound quality, absolutely amazing. No signal loss after "shaking" or "twisting" it, nothing of the sorts that some cheap or super old cables might give you. It is well worth the money spent.
