Good choice in music.

Probably using a moderate amount of distortion on the amp with his guitar's volume turned down. Looks like he's playing with his fingers too. There's many amps out there that could you a comparable sound. I'd suggest a 5w or less, class A/B such as the Blackstar HT amplifiers or Blackheart series. 5w is more than enough for a small gig nevermind the bedroom.
When altitude dropping, my ears started popping. One more red nightmare...

You would also need some delay. Getting that tone from a practice amp is probably going to be difficult.
