Cable capicitance question

[alteredsounds]

I've read on and off for years about many top players, using 50ft / 100ft cable for top end roll-off, am I totally daft but I dont get it lol.  There's surely a million other easier ways?

I think Eric Johnson is one of many doing it, seems bizarre.  Then again  he is mr mojo equipment freak.  lol gonna get stick for that, I can see the rant coming.

I think it is probably a simple case of using what is knocking around on stage and growing to like it.  I know that I don't like to use anything other than my favourite cable even though the effect of using a different cable is marginal (although there certainly is a difference between certain brands of it in my experience).  If you use a buffer not too far away from your guitar or your guitar has active electronics then the effect will not be as apparent.

There was a funny thread here about making a "vintage cable" simulator pedal.

It would be sweet if it had a dirty push button switch so you could get fake shorts, crackles, and noise.  A "technical problem" simulator.

  I'm sure it's all really cool 'n stuff.
  Noisy cables just suck.
  Hard to tell you have a 'bad' cable until a good one is available for replacement...spare is worth it for just that reason.
  "Grab another cable, and GET RID of that one right now...mark it, dump it in the box"...words of the well prepared soundman.
  Save yourself alotta 'funk sorting'.
