You need a "shielded" cable for guitar to amp. (pedal or not). Shielded means the ground wire is wrapped around the lead wire.

Most Speaker cords are just two wires side-by-side so since they aren't shielded they can pick up interference from other sources as well as hum.

Don't do it the other way around either. Shielded cable doesn't have the capability of handling the power between amp and speaker.

Theoretically, the capacitance in a shielded cable could also cause issues in that application, but that would be the least of your problems.
