I can't hear the video right now, but the noise that is heard through an amp when using distortion is usually not because of the amp itself - unless there is a wiring/grounding problem of some sort (not good). Single coil pickups are prone to hum and noise that are most pronounced when using distortion, playing in a venue that doesn't have good wiring, or while near a TV or computer monitor. There are a few things that people have done to try and overcome this including:
*Using a noise-gate or noise-reduction unit.
*Shielding the guitar and using using a star ground.
*Replacing the pickups with stacked-coil humuckers or some other noiseless design.
*Using a "dummy" or "air" coil.
Each method has its good and not so good points and it is up the you to decide what will work best for you.
Perhaps the most effective of these is the use of noiseless "single coils" which aren't true single coils at all. They are, in fact, humbuckers. But since the the coils are stacked one on top of the other, it doesn't sound like a typical humbucker because only one coil actually senses the string. The second coil (which is wound in the opposite direction than the live coil) bucks the hum. The thing is, though, is that they may not sound quite like real single coils either but they do get pretty close though. A dummy coil works on the same principle and has been used by several manufacturers including Alembic (basses), Fender, and Gibson. In the case of a Strat, for example, the dummy coil would be a 4th coil under the pickguard that has no magnets so it does not sense the strings' movement. While not 100% faithful to the true single-coil sound, these options are a serviceable option that serves many people well and is a good solution to an on-going issue.
