I would like to have live "foot control" over the effects running in the effects loop of my amp. This would mean placing the units (eq, reverb, delay, etc...) around 10 feet from the amp, this results in 20 feet of cable + the length of the chain. I have heard anything over 3 feet of cable in the effects loop will result in the loss/decrepitation of signal and tone. I am wondering how true this actually is, and if there was anything one could do to combat the loss of tone/signal.
