The only bleed that I find to be a problem is click track bleed and it's a real menace. It seems that no matter how careful i am, I still get some. I'm thinking of getting the drummer to track using in ear headphones covered with dt100s.
This headphone leakage through guitar is something I have experienced recently. I was doing some recording a couple of months ago tracking guitar. I had the amp miked up in a different room and I was playing in the control room with headphones. My friend came in from making the tea and said "there's click track coming out of your guitar amp", i didn't know what the hell was going on! Then I realised that the pickups were picking it up from the headphone cable. As mentioned here, I ran it down my back and that pretty much sorted it.
