As i've probably annoyed you all 3 or 4 times already, I'm trying to piece together a new Rig for my bass. I'm wondering what kind of speaker cables are decent to get? I was looking at musiciansfriend.com for ideas, and so many of them are 6 feet or longer. It seems like that's a bit excessive just to plug a head into a cab, which couldn't be much more that 3 feet, right? Am I looking at the wrong cables, or is it for other reason to have them longer. Help is much appreciated. Thanks.
