I use this planet wave 24k gold cable, it is the thickness of 2 normal cables, for my speakers, because its supposed to be the best thing to do. But what about the intrument cable? Is it really worth the money to buy a planet wave or monster brand intrument cable that has the 24k gold metal part? I don't know if i should up grade. I use 30 foot cables so i can move around with the bass, so its alot of money, but is it worth it? I also notice fender makes a instrument where just the very tip of the metal part is gold, it that just as good as all gold rather than just the little tip?
