Katana has been the amp hit of the decade and all other manufacturers have been left in the dust. Our guitarist gigged extensively with a 50 and the sounds he got never ceased to amaze, especially at sub €200. He uses it to record too. He is however, very tech savvy so he really knows how to get the best out of one. That said, they still sound great straight out the box.

Extremely good value and well reviewed across the range. The ones to beat at their price point.

He is a great player and teacher. I have learned a lot from him. The video you mention seems to be affecting all the online guys. Another great teacher is Justin for simpler stuff. 

You didn’t say much about your computer. If it’s a Mac, then GarageBand would be all you need to get started. It has drums, built in amps, keyboard sounds, reverb, delay and will allow you to multitrack very easily. I don’t believe there is a direct PC equivalent but someone will chime in.

your first hardware acquisition should be an audio interface. A basic 2 input model from focusrite or Behringer under 100£ will get you going. It will plug into your USB port and you plug your guitar, mic, keys etc into it.  You monitor through it using headphones or separate studio monitors. That’s all you need to get started. Good luck
