I just picked up a Fender Hotrod amp and have my M13 hooked up using the 4 cable method. The Fender manual tells me to use TRS cables between my effects and the amp's FX loop. I know the advantages of balanced connections, but does the M13's FX send and return support a balanced connection or would I be throwing good money away on cables that won't perform any better than regular instrument cables? (I do have a bit of noise with the 4 cable method set up, but I'm pretty sure it's a ground loop issue).
