Yea...as said prior, you'll be wasting your time and perfectly good cables by cutting them up and rejoining them to make a "y-cable." It will cut your guitar signal output and will sound aweful. It'll either cut the signal in half going to both amps, or may slightly cut the signal going to one and dratically cut the signal going to the second...believe me, haha, I've had experiance with this in my younger days of trying to alter gear to be unique and save money. Just spend the $50 on a splitter pedal. Most splitters out there can allow you to play amp one (channel a), amp two (channel b) or both amp one and two (channel a/b). Ultimately what i'm saying is you'll have the ability to do anything you want to shape your stereo amp sound if you buy the pedal!
