The guitar to amp signal has never been cleaner/noise free until i started using the planet waves 20' circuit breaker cable. Toss out all those generic cables and get one (or more) of these to drastically improve your tone and signal. Currently, the only cable which features a circuit breaker built-in to the plug. Very handy when switching guitars on stage. Quality: according to their website, if you ever have any problems with any of their cables - just send it back for a free replacement. make sure you keep your receipt though!
I think the planet waves circuit breaker cable is an excellent value, since these cables have a lifetime warranty (save your receipt)!
With a lifetime warranty - how could you go wrong? you can spend more if you want monsters or mogamis, but these are just as high quality.
